Kasius is the main antagonist of the first half of Season 5 of the ABC TV series Marvel's Agents of S.H.I.E.L.D..
He is a tyrannical Kree nobleman and perfectionist from an apocalyptic future in the year 2091 and the overseer of the Lighthouse which shelters the remaining human survivors. Growing tiresome of his position of the Kree Empire with observing the survivors, he intended on wipging them all out so he can leave Earth with his fortune. However, after S.H.I.E.L.D. arrived from the past, his plans spiraled out of control with the humans uprising against him, which eventually led to his death.
He is portrayed by Dominic Rains.
A member of the respected and influential imperial Kree family, Kasius was given command of an entire fleet and sent to fight against their enemies. However, according to Kasius, the task he was given by his father turned out to be a suicide mission. When he attempted to retreat, two of his trusted generals attempted to prevent him, but they were both killed by Sinara, a low-born warrior who agreed that the battlefield wasn't a place for someone like Kasius. Kasius managed to hide Sinara's involvement in the assassinations of the generals, and the two eventually became inseparable. Kasius' retreat cost the Kree Empire a strategic outpost and the lives of thousands of warriors.
Regarded as an utter disgrace by his own family and having failed to prove himself as a worthy heir, Kasius' own father chose to banish him from Kree's home-world Hala, leaving Kasius' brother Faulnak to take his place. Kasius was eventually sent into exile to govern the remains of Earth, which was torn apart a few decades earlier by the legendary Inhuman "Destroyer of Worlds". Ruling over the remnants of humanity on a dead rock in the darkest edge of the galaxy, Kasius spent much time trying to regain his father and brother's approval, but still without success. Kasius ruled his domain from the Lighthouse, a giant former human survival bunker that had been converted by the Kree into a space station. He ruled the station and its human inhabitants as a strict master, treating the remnants of humanity, especially the Inhumans, as slaves.
Meeting Jemma Simmons
Having heard of Jemma Simmons, who had saved the life of his own servant Reese, Kasius ordered Sinara to bring her to him. Simmons found Kasius in his suites, picking grapes in his personal quarters as he overlooked the remains of the Earth and noted that not even Hala had views like it before noting that she was the one who had saved the life. Kasius questioned Simmons about her medicine skills and warned her about intervening in his affairs, while also commenting on her beauty. As Simmons claimed that the man would have died, Kasius asked where she had learned her skills, with Simmons claiming that her mother taught her.
Kasius then questioned if she had thought the Lighthouse's law of "A life spent, a life earned" had not applied to her, but Simmons defended herself by stating she had only done what she had thought would make him happiest at the end, which pleased Kasius as he claimed this to be the superior answer to any question he could have asked. Confirming with Sinara that this fight had started over food, Kasius understood that the pressure must have been building among the Humans, so he ordered their Kree Watch to back off before they would carry out a Renewal for the sake of the humans.
As Kasius was commenting on his previous views of humans being inelegant creatures which she was clearly not, he offered Simmons some of his own personal grapes before he then noticed that she did not have her Metric installed and that she also did not have a scar, despite her claiming to have removed it herself. As Kasius continued commenting on how Simmons was a perfect beauty with no scars and such impressive medical abilities, he questioned how she could have ever come from a place as tough as Processing as she had first claimed. As Simmons took her hand back, Kasius wished to see how his servant's scars had faired under Simmons' handiwork.
Upon the orders of Kasius, Reese then entered into his suites and received praise from Kasius for that, as he claimed that the mere fact that Reese had walked there in agony showed why he was the finest of his servants. Kasius then studied the wound on Reese's stomach, which Simmons noted could be saved from scarring, while he noted that this wound could be hidden. However, after noticing Reese was injured and would probably be scarred on his face which meant he was no longer perfect, Kasius ordered Sinara to execute Reese using her orbs which punched straight through Reese's chest.
Despite Kasius continuing to note how perfect and talented she was, Simmons was utterly disgusted by Kasius' merciless act of violence against a defenceless man, until Kasius furiously ordered her to be silent. Frustrated by her constant questioning and in order to make her his new servitor, Kasius planted inside her ear Resse's deafening substance before speaking with Sinara while Simmons reacted in fear due to her sudden deafness. Later, after Simmons was dressed as one of his servitors, Kasius welcomed her and complimented her appearance, just as his guests arrived in a large spaceship.
Testing an Inhuman
While awaiting the arrival of Basha, Kasius had some of his make up redone by his personal servants and commented on his own fashion choices. Just as Sinara arrived with Basha's Emissary, Kasius warmly greeted him and offered a Martini, which the Emissary rejected before informing Kasius that Basha would not be joining them as she preferred to eat of her ship. Despite being mortified by Basha's rejection of his hosting, Kasius insisted he was not offended.
As the Emissary left, Kasius then requested some good news, but was informed by Tye that his Inhuman charge Abby had still been failing in her training ahead of the ceremony which Kasius had been organising for Basha. Enraged by all this bad news, Kasius began smashing the Martini glasses and roared at Tye in utter fury. However, it was then suggested by Sinara to let Jemma Simmons train her due to her skills as a medical practitioner, as Kasius switched off the defeaning device in her ear and informed her that he had a problem which he hoped, for both their sakes, that she could fix quickly.
Simmons was taken to Abby where she found her still suffering from seizures which he plagued her ever since her own Terrigenesis, with Sinara reactivating Simmons' hearing while Tye gave her the task of fixing Abby. Having given Simmons just a few hours to give Abby some pointers in controlling her Inhuman powers, Kasius and his men came in ended the lesson and took Abby to his arena. Ignoring Simmons insistence that they needed more time to finish her training, Kasius told Abby that he looked forward to seeing her performance in the ceremony before then ordering Tye to take her away.
Having silenced Simmons once again to keep her from speaking out against his methods again, Kasius spoke with Sinara and questioned if she had intended Simmons to fail helping Abby and be punished, believing that Sinara was jealous that Kasius had found her pretty. Although Sinara did not answer him, Kasius came to believe that she had only wanted him to be happy before he questioned what made Simmons so difficult and thus capable of helping Abby with her new abilities where Tye had failed. Sinara answered that it was Simmons' compassion which made her different from all the others.
Kasius and his own people greeted Lady Basha upon her arrival, with Kasius expressing his hope that her journey onto the Lighthouse was not too difficult. They discussed how Kasius had been able to build a new life for himself using the remains of the Earth, with Basha still making some quietly insulting comments to her host which Kasius chose to ignore, instead leading Basha to come and watch the upcoming ceremony.
Kasius and Basha took their seats as Abby stepped onto the battleground, with Basha noting that Kasius had promised her a Inhuman warrior and had presented her with a small child, with Kasius noting that with Inhumans looks could be deceiving. Kasius then watched as Abby got thrown around in battle when faced off against Basha's unnamed champion, who proved himself considerably stronger than the terrified girl. However, just as Abby looked to be destroyed, he witnessed Abby using what she had learned from Jemma Simmons' lessons to defeat and finish off her dangerous opponent.
Once the battle between Abby and the Beast was over, Kasius and Basha cheerfully discussed his work with the Humans, with Basha noting how impressed she was with what he had done on Earth, making his disdain for the planet well known as they drank Martinis together, with Kasius being quietly insulted by her words. As they were drinking, Abby was brought into the room by Tye before Kasius allowed Basha to purchase Abby for her uses, with Basha handing over her valuable coins in exchange for the Inhuman Control Device which would give her power over Abby's Inhuman abilities.
Witnessing Abby being taken away towards Basha's Ship, Simmons desperately tried to protest as Sinara stood between her and Abby and threatened Simmons with her two deadly orbs. However, Kasius insisted that they should not be rash now, noting that Simmons had demonstrated her worth to him by nurturing Abby's powers since her Terrigenesis and ensuring her victory in the fight. Kasius and Sinara prevented Simmons from having a say in this, ignoring Simmons protests over him selling Abby away, with Kasius noting that without Simmons' work, she would not have made such a high price.
When Kasius and his men had been tipped off by human survivor Deke Shaw that the newly arrived Daisy Johnson was making her way to Kasius' level to rescue Jemma Simmons, they set about capturing the legendary Inhuman. Having witnessed her using all her powers, Kasius and his forces trapped her in between two glass walls and started pumping gas in it. As Kasius, Sinara and Kree soldiers arrived with Deke, as Kasius was pleased that they got the Inhuman who destroyed Earth in his clutches.
With Johnson his captive, Kasius had her Inhuman blood drained for testing while he explained how he saved humanity, explaining that when he arrived the Earth was nothing more than a dead organism which he had seen potential in, noting that he had had a vision and now, with her arrival, that vision could finally come to fruition. Kasius went on to explain that when he arrived on the Earth he had done everything he could to help the humans, only to find they were still clinging onto their stories of heroes, one of which was the story of Quake and how S.H.I.E.L.D. would return in order to save them.
Johnson insisted that she had not intended to arrive there, only for Kasius to note that Jemma Simmons had arrived at the same time, with no Metrics and skills far beyond what she should have ever been capable of. Kasius questioned how many more than traveled from the past with her, but Johnson insisted that there was nobody else, so Kasius then noted that he believed Johnson had come to aid him, which she denied. Kasius explained that he had bidders coming to the Lighthouse to buy her, which would finally allow him to leave, threatening to torture and disfigure Simmons if she did not obey.
Kasius invited Basha back onto the Lighthouse in order to watch the demonstration of Quake's abilities. Once Ben had been removed from the training area, Kasius had Tye explain the situation to Quake before he turned off her Inhuman Control Deviceon her neck, giving her access to her Inhuman powers. While Quake at first refused to demonstrate her abilities, the threat of harm coming to Jemma Simmons convinced her as she knocked Tye backwards with her powerful shockwave, much to the utter amazement of Basha and the great personal delight of Kasius.
Tye then turned the Inhuman Control Device back on while Basha expressed her shock at seeing the Destroyer of Worlds, with Kasius smugly claiming that he had merely forgotten to ever mention her presence there to Basha, noting that a host of traders were now on their way to try and purchase her. Upon hearing this, Basha offered to make Kasius a preemptive bid for Quake, with Kasius noting that while this would be appreciated, as Basha had previously made it clear that she prefered dining on her own ship rather than with him, this meant that she was out of the running for buying Quake.
As the annoyed Basha left, Deke arrived seeking his payment for bring Kasius Quake, so Kasius handed over one of the Rhodium coins which Basha had paid for Abby with, noting that a metal like that would be worth more than all of the credits Shaw had ever been able to earn. While Kasius thanked Shaw for bringing him Quake, he noted that Sinara was concerned about the prophecy which told of Quake and others from the past saving the Earth from its destruction, destroying what Kasius had built. Kasius ordered Shaw to seek out anybody else who may have arrived, which he promised to do.
Testing Jemma Simmons and Quake
While relaxing inside his suite, Kasius listened to his classical music while tasting the foods brought to him before then ordering Jemma Simmons to bring him some water, only for Sinara to burst into the room and throw Simmons to the ground, smashing the glass on the floor. Sinara then presented Kasius with the welding device which, Simmons had used to burn Reese's wound, noting that there was somebody else who had assisted her in saving Reese, making Kasius suspect that more people had traveled through time.
Kasius then ordered Tye to bring Daisy Johnson to him, as he stood opposite her with Simmons. Kasius explained that he now believed the pair of them had lied to him regarding the other person who had aided Simmons, as that person seemed to know her. Johnson still insisted that it was just herself and Simmons who had traveled through time, noting that for some twisted reason, Simmons was unable to hear what they were saying. Kasius then had Ben brought into the room, noting that he could confirm if they were telling him the truth or not with his own Inhuman mind reading powers.
Turning off Ben's Inhuman Control Device, Kasius asked Simmons who the woman who helped her was, although Simmons insisted that she had no idea who the woman was, which Ben informed Kasius was the truth. Kasius then asked if they had come through time together or separately, with Johnson questioning why this mattered at all as Kasius explained that the prophesy spoke of S.H.I.E.L.D., therefore if she and Simmons came separately, then more S.H.I.E.L.D. agents could have come without them. However, Johnson informed Kasius they came together and alone.
With Simmons unable to hear them, Kasius had Johnson explain the story in detail, while he stood between them to ensure Simmons could not read Johnson's lips. She then told Kasius how their team became trapped in the Framework, resulting in the death of Director Jeffrey Mace, with Simmons' lover Leo Fitz being the one who caused Mace's death. She claimed that Simmons could not handle this and they spoke alone together before a mysterious man knocked them out and they awoke in the future. Kasius turned to Simmons and asked the same question, wishing to hear the same story.
Much to Kasius' surprise, Simmons told the exact same story beat by beat, explaining her sorrow at witnessing Fitz kill Director Mace while working for HYDRA within the Framework. She told Kasius how Johnson had taken her to a diner to talk in private when a mysterious man had ambushed them, causing them to be sent to the future with no understanding of what had happened to them. Having confirmed with Ben that this was the truth, Kasius turned his Inhuman Control Device back on and had the Kree Watch escort all of them out of his suites, before reassuring Sinara that he was still concerned.
Meeting Leo Fitz
Having gathered together all those looking to buy Quake from him, Kasius greeted everybody in his suite into the Lighthouse where he offered food and drinks for his guests. With Sinara by his side, Kasius gave a speech to welcome everyone before the Kree Watch brought Quake before them in chains. As Kasius was speaking however, Leo Fitz posing as Boshtok a wealthy Space Marauder stepped forward and demanded they not have an exhibition, but instead have Quake fight to the death to prove her power to them, which had greatly surprised Kasius.
Kasius agreed to keep an eye on the Marauder after Sinara expressed her suspicions on him, before he greeted Gaius Ponarian and welcomed he back onto the Lighthouse, with Ponarian happily telling Kasius that it was a pleasure to have returned after so many years.
Kasius then went over to investigate Fitz who was seen speaking to Jemma Simmons. Kasius explained to him she was only allowed to hear his own voice, Fitz was displeased, forcing Kasius to allow Simmons' hearing to return. Kasius explained how Simmons had also traveled through time, so when he was asked if she was also for sale, Kasius replied that she would be sold only with Quake as she could be a good motivation to the Destroyer.
Kasius sent Simmons away to check on the harvest while the duo discussed how members of Kasius' Kree Watch had recently organized a Terrigenesis ceremony in order to find new Inhumans for his guests to purchase, which had included the young Flint before he had escaped. Fitz made it clear that he would pay whatever Units he needed to in order to acquire Quake, with Kasius noting that he had heard that he was a man of some expensive tastes and that they would soon learn if he did have the resources required.
Kasius and his guests then sat down for dinner together as Ponarian asked how the Vrellnexians he had sold him were getting along, with Ponarian noting that he had hoped the creatures would provide him with a small triumph in the wake of his exile from the Kree Empire. Upon hearing this, Kasius insisted that he was never exiled from Hala but had merely been sent away by his own father to oversee the Earth project personally, with Ponarian then jokingly noting that Faulnak had remained behind to oversee the family empire and it's entire vast fortune, much to Kasius' great annoyance.
Getting to his feet, Ponarian announced to the entire table that he had brought them all fresh Xandarian Snails to eat, much to Kasius delight. Changing the subject, Lady Karaba questioned how Kasius kept the Humans under control, with Fitz correctly assuming that he had them kill each other in his Renewals. which Kasius then confirmed while smiling. Kasius then informed the group that the first demonstration would soon begin and one Inhuman would soon be withdrawn upon death. When Fitz insulted Ponarian for his snails, Kasius stopped a fight by laughing out loud.
Welcoming all of his guests into the fight pit, Kasius privately spoke with Leo Fitz as he expressed his delight of having a man like him present at the auction. Kasius then gave a speech in which he introduced Ben and his Inhuman power to read minds and predict enemy attacks. Kasius then introduced Melinda May who he explained had also travelled through time with her personal friend Quake and had also been trained by the organisation S.H.I.E.L.D. to be a deadly assassin.
As the fight between May and Ben began, Fitz questioned how many others had travelled through time with Quake, with Kasius noting only Jemma Simmons and May had so far been discovered, while Sinarawas convinced that there would be more. They also discussed how Ben would fare in the Kree Empire's army, with Fitz questioning Kasius over his relationship with his own father, noting that Gaius Ponarian had made it appear that he had been banished, which Kasius denied was the truth. Fitz noted that his own father had been disapproving and that his actions to win his approval had left him scarred, which Kasius understood.
Watching Ben easily overpower May using his Inhuman abilities, they continued to discuss his reasons for selling Quake, with Fitz theorizing that it was to redeem himself in his father's eyes, which he confessed was more or less true. Although May continued to fight, Ben proved that his power allowed him to overpower her. However, before Ben could finish her off, Fitz suddenly claimed that the fight bored him and insisted that May be sent to Earth to fend for herself against the Vrellnexians while they prepared to finally see Quake fight, which Kasius reluctantly agreed to.
Back in his suites, Kasius witnessed Lady Karaba and Ponarian both attempting to bid for Ben, with Karaba offering five Culverian Blasters while Ponarian offering ten thousand Units. However, Kasius informed the group that he would now not be selling Ben, much to Ponarian's annoyance as Kasius turned off Ben's Inhuman Control Device and allowed him to read his own mind, much to Ben's horror. Kasius then informed the group that Ben had just lied about Quake and Simmons being the only ones to travel through time and, despite all of Quake's desperate pleas, ordered Sinara to execute Ben with her orbs.
News of Kasius selling Quake eventually reached Hala and Kasius was informed that his father was sending Faulnak in person to see the Destroyer and possibly buy her for his Kree armies. While Kasius was speaking with Lady Karaba, he was confronted by a furious Fitz who demanded to know why his brother was also coming to bid on Quake. While Kasius delighted in the news, Fitz made it clear that he was enraged and noted that he had been promised a chance to buy Quake, which Kasius promised to still entertain, but advised him to consider his other many Inhumans on offer.
Quake, Fitz and Jemma's Escape
While his guests arrived in the fight pit, Kasius spoke to Sinara as he noted that their fate was soon to be at hand. He was then interrupted by the arrival of Faulnak, whom Kasius welcomed into the Lighthouse while Faulnak immediately expressed his distaste for the place. Faulnak insisted that he had only come due to their father's orders, with Kasius claiming that it was an honor for their father to have sent his most trusted messenger. Faulnak then noted that Quake should not disappoint him, or he would express his mighty rage, which had somewhat unnerved Kasius.
Just as Kasius promised that Quake would soon be fighting one of his most prized Inhumans, Faulnak explained that he had no desire to see one of Kasius' homegrown experiments fight, but instead insisted that Quake must fight a Kree warrior to show her worth. Looking around the room, Faulnak suggested that Sinara should fight Quake, much to Kasius' horror as he insisted that Sinara was not prepared for battle, although Faulnak dismissed this by questioning if she was truly Kasius' greatest warrior, noting that he hid behind her as though she was, which Kasius was unable to answer.
Despite his reluctance to lose her, Kasius agreed to have Sinara fight to the death when Faulnak suggested that perhaps he was no longer seeking their father's approval. While Faulnak walked away, Kasius approached Sinara and noted that this battle presented him with a tremendous opportunity. Kasius noted that everything he had been working for would now come down to this one battle, which Sinara noted would be to the death. Kasius then confirmed this would be the case before telling Sinara that he had every confidence that she would soon provide them all with a great battle spectacle.
With everybody sat down, Kasius then introduced Daisy Johnson, reminding everyone of her story of her destroying the Earth with her Inhuman abilities as she stepped into the fight pit to face off against Sinara, with Faulnak questioning if such a small and unassuming girl could possibly be the feared Destroyer of Worlds. Having turned off Quake's Inhuman Control Device, and knowing how deadly Quake's Inhuman power could actually be, Kasius first ensured that there was a force field between themselves and the upcoming fight, with Kasius then inviting his brother to give the opening commencement.
However, rather than wait, Sinara began firing her orbs at Quake, starting the fight while Faulnak scoffed that Sinara was no longer obeying any of Kasius' orders. Kasius, Faulnak and the others then watched the fight unfold, with the Inhuman and Kree proving to be equally matched in fighting abilities but with Quake's power giving her a distinct advantage, allowing her shockwaves to launch Sinara across the fight pit with incredible force. Kasius still found himself emotionally torn while watching the fight, wanting Quake to prove her value while not wishing to see Sinara killed as a result.
Just as Quake defeated Sinara, Leo Fitz revealed himself to be a traitor as he drew an I.C.E.R. and struck Gaius Ponarian across his face with it. Before Kasius could react, he was attacked by Jemma Simmons who attempted to slit his throat with a knife while Fitz removed the force field allowing them to escape. Kasius watched this unfold in horror, clutching his wounded cheek as they escaped.
As the hunt for their escaped criminals began, Kasius returned to his suites and examined the scar given by Jemma Simmons, horrified by his new imperfection. While Kasius questioned if it would be noticeable, Faulnak arrived and claimed that new scars should be regarded as badges of honor for a warrior, noting that his brother's priorities were misplaced. Faulnak asked about Quake, with Kasius confirming that due to the Inhuman Control Device, she had no power, no ship and nowhere to run, so it would only be a matter of time before she would finally be recaptured.
However, Faulnak was unimpressed by this and intended to lead the chase of the fugitives by sending his warrior Maston-Dar, although Kasius reminded him that he was in charge of the Lighthouse and that Sinara could handle the task. However, Faulnak disregarded Kasius' opinion and ordered Sinara to bring all the human weapons they had for Maston-Dar who preferred using the human's own weapons against them, and Kasius silently told Sinara to comply. Having made it clear that he was now in charge, Faulnak ordered Maston-Dar to spill blood before smiling at his horrified brother.
Later, Kasius walked through his suites alone, obsessively touching his new scar before he met with Sinara alone and told her that it was in their best interest to make Faulnak believe he was in charge as he noted that he was his only way to return to Hala and regain their father's approval of him. However, Sinara still appeared quite disgusted by Kasius' behaviour, with Kasius desperately trying to win her approval by defending his decision to put her in the fighting pit, only for Sinara to call his begging repulsive. However, Kasius noted that he knew Sinara would discover where Quake was before Maston-Dar.
Kasius then remained with Faulnak, waiting for the fugitives to be delivered back to them, discovering Faulnak examining several of the human's weapons including World War II rifles, with Kasius noting that while Faulnak was interested in the power behind weapons while he was fascinated by the craftsmanship. Although Kasius attempted to suggest that they could find a cross-section of interest with these guns, Faulnak insulted his brother's priorities again, claiming he had preferred killing his enemies with his Kree blade.
Despite his attempts to make peace, Kasius was belittled by his brother on several occasions, calling him a coward and weak in regard of his shameful past in losing a key outpost of the Kree Empire, despite Kasius noting that he was put in command of his own fleet with no prior training. Enraged by Kasius' excuses, Faulnak shot at him twice, claiming that he should have fought and died rather than running and insulting him for his relationship with Sinara, despite Kasius explaining that Sinara had saved his life, with Faulnak reminding him how they were exiled from Hala for abandoning their post.
While Kasius argued that he was not weak, but had built his strength by surrounding himself with loyal soldiers like Sinara, Faulnak furiously claimed that he had brought shame upon their family and would be haunted by the blood of the Kree Soldiers he had failed. While Kasius stood silently, Faulnak then compared his brother to the Earth, noting that it had once been full of promise with the Kree's plans for the Inhumans, but was now nothing more than a broken spec of dust. Faulnak then promised that when Maston-Dar returned with Quake, he intended to immediately leave with both of them.
While Kasius and Faulnak continued to await news on their hunt for Quake and the others, Sinara eventually returned and informed them that the fugitives had escaped the Lighthouse to head to the Earth with the aid of friends. Faulnak was disgusted by what he called Kasius' incompetence as his Kree Watch had allowed Quake to escape and they had only just learned that there were still survivors on the Earth, while Kasius was unable to muster to courage to speak.
Faulnak insisted that they ready a ship to head down to the planet, noting that Maston-Dar would be able to survive against the Vrellnexians that covered the planet. However, Sinara revealed to them that Maston-Dar was dead before confessing that she had killed him herself. Kasius feared that the murder of his servant would enrage his brother, but to his surprise, Faulnak instead burst out laughing as he, impressed by this bold action, Faulnak expressed a desire to hire Sinara in his place, as Kasius watched on in horror at the possibility that Faulnak could also take Sinara away from him.
Mortified by what Faulnak was saying, Kasius took a bayonet from the table and stabbed his brother through the back, angrily stating that Sinara was not an object Faulnak could simply purchase. Standing over his dying brother, Kasius confessed that he knew their father had sent him on a suicide mission with the Kree Empire, noting that the generals had been killed by Sinara, noting he had never been built for battle. As the mortally wounded Faulnak spat out blood, he accused Kasius of cowardice once again for having stabbed him in the back, so Kasius responded by dealing a final blow.
With Faulnak finally dead, Kasius dropped down beside him and closed his eyes, reciting the words of a life spent, a life earned. The hands covered with his own brother's blood, Kasius rubbed his hands across his own face as he approached Sinara and told her that once they would have captured Quake and blamed her for Faulnak's death, they would reach the glory they craved for, claiming that this would finally allow him to reclaim his father's approval and be allowed to return to Hala as a hero, no longer the disgrace that Faulnak and the others had regarded them as for so long.
Punishing the Humans
Kasius was informed that all of the fugitives had used the Trawler to escape to the surface of the Earth where they had vanished, greatly annoying Kasius as he slammed his fist down on the table. As he noted that it was possible that they could have survived the crash, Kasius claimed that Quake had proved herself to be. Seeing Sinara's reaction to this news, Kasius questioned if she wanted to go after Quake and all the others, which she confirmed that she did.
Kasius granted her wish before explaining that he would now focus on punishing all the humans of the Lighthouse who he blamed for aiding the fugitives, claiming that he had been far to lenient on them for too long. As Sinara questioned if he meant the Renewal, Kasius walked over to the terrified Ava and claimed he intended to cause retribution. Kasius then ordered members of the Kree Watch to cut off the power across the Lighthouse, removing the heat and water, before they went to the lower levels and sent all the Vrellnexians back upstairs where they massacred dozens of the humans.
While the Vrellnexians were killed thanks to the efforts of Alphonso Mackenzie, Yo-Yo Rodriguez and Flint, Kasius sent Sinara down onto the planet's surface in order to find and capture the escaped S.H.I.E.L.D. agents. Using a camera on Sinara's helmet, Kasius confirmed that the fugitives had survived the Trawler's crash, although they could have been killed by the Vrellnexians. As Sinara requested her orders, Kasius ordered her to continue following their trail, noting that they knew the human's weaknesses and told her to show them no mercy when she finally found them.
Losing Control of the Lighthouse
Much to Kasius' horror, Hek-Sel informed him that the humans had survived the attack and killed all of the Vrellnexians along with eight members of the Kree Watch. When Kasius questioned how this had been possible, Hek-Sel informed him that the humans had obtained guns, leading to Kasius furiously questioning where on the Lighthouse they had been able to find weapons. He was interrupted when one of his slaves dropped a box, leading to Kasius furiously threatening to kill her.
As the terrified humans, led by Ava, quickly left to continue loading his ship with his personal items, Kasius continued to ponder the concept of there being an uprising just as he was ready to leave the Earth once and for all along with Quake. Deciding on a new plan now that the Vrellnexians were dead and all the humans were rebelling, Kasius ordered Hek-Sel to have the Kree Doctor go and awaken the recently resurrected Tess in the wake of her murder at the hands of the Vicar. Looking out over the Earth, Kasius claimed that he would remind the humans that he was not their enemy, but their god.
Kasius ordered Tess to bring him Flint along with every child under the age of ten, with all the Terrigen Crystals. Also seeking to reclaim Quake, Kasius demanded that the remaining S.H.I.E.L.D. agents to motivate her to return, threatening to destroy the entire human race at the touch of a button if she had failed. While Kasius waited by the fighting pit, Hek-Sel eventually informed him that Tess had returned, only to discover much to his annoyance, that she had failed to bring what he wanted. Enraged, Kasius threatened to kill Tess with all the humans but she explained that she was not empty handed.
Tess revealed that the humans, led by Alphonso Mackenzie and Yo-Yo Rodriguez had taken over the entire research floor and were now threatening to take away his abilities to breed Inhumans until Kasius went to meet them, or they would destroy all the Terrigen Crystals and the Inhuman DNA he had been storing, using Kasius' own words against him as she noted that they would be able to burn everything at the touch of a button. Enraged, Kasius then chocked Tess before dropping her to the floor and storming out, ordering Hek-Sel to bring Tess with them in order to finally meet with the humans.
As requested, Kasius to meet with the Humans, protected by his four members of the Kree Watch including Hek-Sel. Upon arriving, Kasius expressed his surprise upon seeing Yo-Yo Rodriguez there before Alphonso Mackenzie warned him not to move under the threat of him destroying everything Kasius had for breeding Inhumans. However, Kasius still remained unintimidated, noting that while they thought they were invincible, they would soon submit to his rule.
Despite all his threats, Rodriguez merely laughed in his face before calling Kasius a coward who hides behind those who do his bidding. Kasius then noted that he found it ironic that they were attempting to trade humans for Inhumans, noting that he felt the defining feature of their kind was that they would also turn against one another. Kasius noted that soon Sinara would have captured Quake and they would have no choice but to surrender to him, so he decided to offer them one final chance to stand down, or to experience the same horrific suffering as Tess had been through many times over.
Kasius claimed he was a god to be feared, only for Mackenzie to note that vengeance and torment were tools of the Devil, leading to Kasius threatening to show them a Hel they could not even imagine. As Rodriguez insulted him, Kasius witnessed the arrival of Flint who joked that Kasius did indeed have a funny way of speaking, so he showed them the detonator to his bombs and demanded that they surrender to him. Rodriguez made a move to steal it, but the shield generated by the Kree Watch blocked her path, leading to Kasius mocking her attempt as he had prepared for the attack.
As punishment for their attack, Kasius activated the bombs he had placed throughout the Lighthouse, intending to wipe out the humans. However, when all of the bombs were activated, Kasius realized that Mack had been stalling in order to allow Gunner and the other humans to move the bombs downstairs and also take the people up. While Kasius reacted to his mistake, Tess ran to her allies while Flint noted that the humans were safe from him, with Tess happily adding that they were now free of his rule. Enraged, Kasius noted that the four humans before him were not safe from him before Mack destroyed all of the Terrigen Crystals and led Yo-Yo, Tess, and Flint in fleeing from the scene, as Kasius screamed in rage.
Seeking to know what was coming, Kasius went to speak with his seer and was informed that the S.H.I.E.L.D. agents were returning to the Lighthouse onboard Zephyr One. As Kasius was then leaving the room, Hek-Sel came to inform him of this, only for Kasius to make it clear he was already aware as he ordered Hek-Sel to prepare a squad of Kree Watch to end the fight once and for all. When Hek-Sel questioned how he knew this, Kasius noted that while the Humans had a Seer predicting the future, he had one of his own.
Having been alerted to Sinara's death, Kasius stood vigil beside her body in his quarters, mourning his fallen ally. He demanded that his Kree doctor fix Sinara, and shot him dead with a pistol when the doctor insisted Sinara was dead. In desperation, Kasius summoned Tye to his quarters and infected him with odium to set him upon his enemies; though Tye managed to infect Coulson in the ensuing fight, he was killed by Daisy. Kasius then ordered that his Inhumans be gathered to counter S.H.I.E.L.D., but the Kree Watch were ambushed and killed thanks to a trap set by Fitz, and the Inhumans freed. Finally realizing that S.H.I.E.L.D.'s aim was to travel back in time and avert the dystopian future, Kasius came to the conclusion that if he was able to stop them, Earth would not be destroyed, and thus his father would be able to take over Earth in pristine condition, guaranteeing a better future for his family and himself.
In a final, desperate attempt to succeed, Kasius took his Seer, a future version of Yo-Yo, and held her hostage in front of Mack. After taunting him, Kasius consumed a vial of odium and slit Yo-Yo's throat, and engaged the enraged Mack in a vicious hand-to-hand duel. Just as it seemed Kasius would kill Mack, Jemma intervened and infected Kasius with the same deafening device he had used on her and countless other human victims (one of whom had been freed by her, Coulson, and May mere minutes before her arrival to save Mack). Distracted by the pain and silence, Kasius was finally killed when Mack impaled him from behind with his shotgun axe, bringing an end to his rule.
At first sight, the Kree nobleman Kasius does not seem to be as violent than any average Kree. Instead, he generally speaks calmly and quite politely, albeit in a highly confident way. However, there is no doubt about his cruelty: he had one of his servants executed due to the latter having a simple scar on his forehead; and an Inhuman slave executed because the latter lied to him; and he threatened to have Jemma Simmons tortured and disfigured if Daisy Johnson did not obeyed him. Kasius harbors a high degree of bitterness regarding his exile and is motivated above all by his own personal interest, which is getting great fortune to win his father's favors. Thus, he was willing to let his own faithful and loyal bodyguard Sinara fight to the death with Quake and intends to destroy the Lighthouse and all the remaining human population once his work was completed.
Prior to his exile, Kasius came to realize that he was not a fighter, whereas his brother and Sinara both were. He shows a high degree of cunning as he tried surviving an unwinnable battle by fleeing whereas his fellow Kree would stay and fight till the end even if it was suicidal. To Kasius, such attitude is pure pragmatism and not cowardice. He is also shown to care and be protective of Sinara, refusing to let his brother, Faulnak, take Sinara away and killed him to prove his feelings for her.
Thus, Kasius is somewhat of an anomaly amongst the Kree. He still has the Kree predisposition towards control and dominating his enemies, but he chooses to do it through manipulation and cunning whereas the vast majority of his Kree brethren would prefer to do it through brute force and violence.
- Kasius is the third main antagonist of Marvel's Agents of S.H.I.E.L.D. to be created specifically for the show. The first was Jiaying, the main antagonist in the second half of Season 2, and the second was Grant Ward, the main antagonist in the first half of Season 3.
- He is one of the few main antagonists in the series to be killed by a protagonist other than Phil Coulson, including Hive, who was killed by Lincoln Campbell, Eli Morrow, who was killed by Ghost Rider, and Graviton, who was killed by Daisy Johnson.
