Villain Overview

You may call me... Infinite... in the brief moments that remain to you.
~ Infinite introducing himself to Sonic the Hedgehog.
That day, I gave up my own unsightly face. And I let go of the old me, the one that was so weak, so that I could become stronger. And then, at last... I obtained the power. The power to make all yield to my will. I... was... REBORN!
~ Infinite explaining his origin.
...Hahaha! Interesting. All this time, I've been going through the motions. I've actually grown tired of this world as it is. Let's do it, Doctor! I'll help you change this world!
~ The Jackal agreeing to serve Dr. Eggman and conquer the world.

Infinite is the central antagonist of Sonic Forces and the main antagonist of its DLC prequel Episode Shadow. He is the Avatar's arch-nemesis and one of Sonic the Hedgehog's most dangerous enemies.

He is a jackal who used to be called the "Ultimate Mercenary". After his encounter with and defeat at the hands of Shadow the Hedgehog, Infinite became obsessed with the desire to be the strongest until he is never defeated again. After Dr. Eggman enhanced him with the Phantom Ruby, he became the Eggman Empire's second-in-command who helped defeat Sonic and conquer most of the world.

He was voiced by Takashi Kondō in the Japanese version, and by Liam O'Brien in the English dubbed version, who also played Archer in Fate/stay night, Caius Ballad in Final Fantasy XIII-2, Gill in Street Fighter V, Count Waltz in Eternal Sonata, as well as Nephrite and Gaara in the Viz Media dubs of Sailor Moon, Sailor Moon Crystal, and Naruto.



Infinite taking the Phantom Ruby from Dr. Eggman and seeing his alleged future.

Infinite was originally the leader of a team of mercenaries named "Jackal Squad".

One day, he saw Dr. Eggman in his base with Cubot and Orbot and decided to have his squad raid it for its technology. With the newly discovered Phantom Ruby, Dr. Eggman inadvertently created Egg Pawn Replicas that he unleashed upon the squad. He still harried on to evade the Egg Pawns and reached Dr. Eggman to deliver a finishing blow. However, he instead strikes the Phantom Ruby with his sword, causing him to see the world in the way he desired to see it: as a desolate and chaotic wasteland. While distracted, he was then pushed to the ground by Eggman and then cornered by his Egg Pawns. But rather than punish him for attacking him, the doctor gave the mercenary a chance to join forces and conquer the world together. Ignoring protests from his teammates, he accepted Eggman's proposal in hopes of making his vision a reality.

Later, Dr. Eggman hired him and the rest of the Jackal Squad to defend his base when it was assaulted by Shadow the Hedgehog. After the Ultimate Lifeform annihilated his squad, the un-phased Jackal promised to show Shadow his power, but was effortlessly defeated, which caused Shadow to call him worthless and warned him to never show his face to him again before teleporting away. Enraged and devastated by both his loss to Shadow and Shadow's words, he began ranting and shouting, angrily declaring that he was not weak.

Driven by the desire to become more powerful, he agreed to be a test subject in order to become Eggman's ultimate weapon. After donning a mask to hide his face and attaching the Phantom Ruby to his chest, the once relatively stable jackal was no more, and the new, monstrous Infinite was born.

Sonic Forces

At the beginning of the game, Infinite debuted inside of a container during his experimentation by Dr. Eggman. After mentioning his burning hatred of Sonic, Dr. Eggman gloated over Infinite in his process and reveres him as his unstoppable creation.

In Episode Shadow, which was set one month prior to the events of the main game, Infinite crossed paths with Shadow again after he had dealt with E-123 Omega, who had previously fought through Dr. Eggman's base. After reminding the black hedgehog of their last encounter, Infinite then unleashed his powers to trap Shadow in an augmented reality. Although Shadow freed himself, Infinite became transfixed by his power and inspired to use it in his agenda against Sonic.

Infinite's replicas.

Infinite assisted Dr. Eggman and his robots in an attack on a large urban center. After Sonic the Hedgehog fought off Eggman's forces, Infinite engaged the blue hedgehog, alongside Replicas of Shadow, Zavok, Metal Sonic and Chaos that he had created, and defeated him. Sonic was then captured and brought to the Death Egg to be tortured before being executed.

Infinite assisted Dr. Eggman with his new powers that enabled the Eggman Empire to conquer 99% of the world, being appointed as second-in-command and enforcing fear and subjugation among the populace. Sonic's friends formed the Resistance against them, but they posed no threat to Infinite's prowess.

Infinite sparing the Rookie after sensing fear in them.

Infinite one time had wiped out a Resistance squad and faced its sole survivor, the Rookie. Instead of killing them, however, Infinite allowed the Rookie to live after he sensed their fear, though doing so also allowed the Rookie to join the ranks of Sonic's friends and later help rescue Sonic.

The Rookie finding the prototype that Infinite dropped

At the Mystic Jungle, Dr. Eggman dispatched Infinite to destroy a copy of the Phantom Ruby Prototype. While there, Infinite encountered and had a clash against Silver. Infinite instantly defeated Silver with ease-though unwittingly drops the Phantom Ruby prototype in their quick battle-and tried to finish him off before he was interrupted by the arrival of Sonic, whom he discovered was still alive. Although Infinite tried to taunt Sonic with his power during their face-off, Sonic fared better whenever he struck him. However, Infinite defeated Sonic again and decided to spare the blue blur after assuming him as no threat. Soon afterwards, the Rookie investigated the Mystic Jungle and found the same Phantom Ruby prototype that Infinite had dropped earlier.

Infinite later meet Dr. Eggman at Green Hill, where he purported the accomplishment on his mission to destroy all Phantom Ruby Prototypes. Dr. Eggman asked Infinite if he had reencountered Sonic. Infinite admitted that Sonic is still alive, but assured Dr. Eggman that the latter was powerless against him. As the jackal then asked to proceed with their plan, Dr. Eggman confirmed that it involved eliminating the entire Resistance. After Infinite left, Tails and Classic Sonic revealed themselves before Dr. Eggman after hearing his conversation with Infinite and chased after the evil doctor. After Classic Sonic defeated him from the chase, Dr. Eggman proclaimed to Tails and Classic Sonic that his plan will occur in three days, before escaping.

Shadow defeating his replica before explaining to Sonic about Infinite's powers.

Sonic confronted a Shadow replica to question him after witnessing him aid Infinite and fight against the Resistance, only to be assaulted. Luckily, the real Shadow appeared and defeated his replica before it could land a blow on Sonic. Shadow then explained to Sonic that Infinite has the ability to alternate reality and create replicas of old foes that are formidable as the originals, something of which he had learned from during their second encounter in Episode Shadow when Infinite had observed him in the augmented reality and became inspired to create replicas of him as well.

Infinite preparing to unleash his powers among the Resistance.

Meanwhile, the Resistance lead an assault on the Eggman Empire at Metropolis, as they believe that it was their chance to succeed. However, Infinite appeared at Metropolis and unleashed his Phantom Ruby's powers among the Resistance, using his reality warping powers to cause panic and wipe them out. The Rookie managed to escape from the augmented reality and was the last man standing once he encounters Infinite. Infinite tried to intimidate the Rookie like last time, but the Rookie now stands up to him after being reminded of Sonic, whom helped encourage the latter with his words. During their battle with each other, Infinite recognized the Rookie as the Resistance member he had spared earlier (after sensing their very same fear of him from the last time) and decided to finish the Rookie off by summoning several cannons before them. However, once Infinite opened fire, the Rookie avoids the cannon blasts, as they had the Phantom Ruby prototype that counteracts Infinite's powers. Though shocked, Infinite reminded the Rookie that they have two days left until he initiated the plan to destroy the entire Resistance.

Infinite unleashing Null Space in hopes of ridding Sonic with it.

After destroying the Phantom Ruby's power source on the Death Egg, Dr. Eggman witnessed its destruction and orders Infinite to follow him to Metropolis. Once Sonic confronted Dr. Eggman there, Dr. Eggman ordered Infinite to unleash a void called Null Space that sucks Sonic into it along with the Rookie, whom followed in to save him. As Tails became confused after they had destroyed the Phantom Ruby's power source, Dr. Eggman revealed to him that he had a backup power source under Metropolis. However, Sonic and the Rookie soon escaped Null Space with their efforts combined and made it back to Metropolis, where they arrived before Dr. Eggman and Infinite. While Infinite was only slightly displeased about this, Eggman furiously had them retreat to the Eggman Empire Fortress.

Infinite creating a virtual sun to end the Resistance.

Once the Resistance Army stormed the Eggman Empire Fortress, Infinite confronted them with an army of his replicas. While facing Sonic and the core members of the Resistance, including the fully repaired E-123 Omega, Infinite created a virtual sun above the entire Resistance army, which Dr. Eggman pointed out will fall and destroy them. Tails soon noticed the Phantom Ruby prototype that the Rookie possessed in hand. Once Tails observed it, he hypothesized that the Phantom Ruby Prototype only reacts to the person whom activated it, encouraging the Rookie to run towards the virtual sun and use the prototype to disable it, though also destroying the prototype in the process.

Infinite fading from existence due to his defeat.

Infinite became weak after his attempt to create the sun, forcing the sadistic warlord to retreat to the center of the fortress with Sonic chasing after him. Once they engaged into battle with each other, Infinite recharged the Phantom Ruby on him and was about to finish Sonic but was then foiled by the Rookie's arrival. The Rookie and Sonic then contended with Infinite head on and defeated the sadistic warlord. Infinite is last seen and began to fade away due to his defeat, but not before saying that he can still fight, as the jackal headed towards the power source reactor. Plus, Infinite's remaining Phantom Ruby prototype was still intact, in which Sonic and the Rookie chased after. While in pursuit of the fortress' interior, they discover it to be the place where Infinite came to be.

The Death Egg Robot

The reactor was destroyed, but before the heroes could celebrate just yet, Dr. Eggman appeared before them in his Death Egg Robot, revealing to them that the reactor was only a decoy and that he actually had the real Phantom Ruby incorporated in the Death Egg Robot, all the while boasting about how he had created a robot more powerful than Infinite. Using his Phantom Ruby-empowered mech, Dr. Eggman began to conjure more replicas of his army than ever, now consisting of replicas of Infinite.

After Sonic, Classic Sonic, and the Rookie defeated Dr. Eggman, the entire replica army disappeared, along with the Phantom Ruby that was seemingly destroyed, leaving Infinite's fate unknown. The Sonic the Hedgehog Encyclo-speed-ia would later confirm that he and his Phantom Ruby prototype were consumed by the original Ruby after his defeat. It's unknown if it means that Infinite is still alive inside of it or not.

Other Media

Super Smash Bros.

Infinite appears in Super Smash Bros. Ultimate as a primary attack-type spirit. His spirit battle is a stamina battle against a metal Sonic the Hedgehog on Big Blue while the screen occasionally flips.


There is no reason to resist. Your savior is no more. I can taste you terror, child. All that anxiety and's delicious. Give in to your fear, flee, screaming, and I'll let you live.
~ Infinite attacking a town.

Infinite is a very cruel, sadistic, manipulative, destructive and power-hungry individual who wants nothing more than to become absolutely powerful, which incited the Phantom Ruby being fused into his chest, and his becoming the second-in-command to Dr. Eggman's army. He is a ruthless warlord who has massacred many innocent lives and does not nearly show pity or remorse for it.

Infinite taunting the Rookie.

He is also extremely overconfident, megalomaniacal and arrogant. The powers that he receives from the Phantom Ruby make him confident in himself, stating himself to be the most powerful creature on earth. He harasses weaker, less powerful people like the Rookie, whom he abuses multiple times throughout the game. At the start he offers to spare the Rookie's life if he/she shows fear, probably meaning he would let his victims escape alive if they are afraid of him so they can spread the word of his power and ruthlessness.

He does not only insult the Rookie but also other stronger individuals like Sonic, whom he calls a "filthy rat". Even before Infinite obtained the Phantom Ruby that made him powerful and mighty, he was already sadistic, barbarous and power-hungry by nature. He did, however, have some affection for his subordinates, as he expressed his initial anger at Shadow for apparently destroying them, though this may have mostly stemmed from the fact that he was humiliated that his followers were defeated so easily by one individual, regardless of who they were.

Initially, he was nothing more than a violent mercenary with no regard to any life. In his first meeting with Dr. Eggman, he even wanted to kill him, only to be intrigued by a vision of a ruined world shown to him by the Phantom Jewel, leading Dr. Eggman to give him the offer to join him in his goal. Infinite immediately took the offer against the words of his comrades and forced his reluctant squad to join Eggman. Later, Infinite reacted calmly news of his squad's destruction at Shadow's hands, further indicating he didn't think much of them.

Despite his extreme arrogance, Infinite is actually cold and calm at almost all times. Even when he loses, which is something he absolutely hates doing, he simply gets shocked and starts talking to himself, but does not otherwise lose his temper. His dialogue is much more theatrical, subdued, and certainly more menacing, probably showing that he loves to taunt his victims just as much as he loves killing them.

Perhaps his biggest weakness, besides his arrogance, is his inferiority complex, as shown after his defeat by Shadow the Hedgehog, where he throws a tantrum because he realized that he was afraid of Shadow. This would culminate his desperation of ultimate power by gaining the Phantom Ruby for himself and becoming the sadistic warlord he is today. Also, he tries to make himself so powerful that no one, not even Sonic or Shadow can defeat him, and continually tries to prove to himself and others that he is not weak. This could be a sign of insecurity, egoism, or just another form of his arrogance.

Powers and Abilities

Before being weaponized, Infinite was a highly skilled mercenary. He is proficient in sword-fighting and has sharpened reflexes. His base agility is also higher than average, being able to traverse an entire jungle in a few leaps. However, he was utterly no match for powerful individuals like Shadow the Hedgehog.

The Phantom Ruby

After obtaining his synthetic Phantom Ruby, Infinite gained the ability to create an augmented reality that achieves form through his imagination and the psyches of his victims. By simply willing it, Infinite will generate a field that allows him to control the movements of his enemies through a gas called "Ruby Mist". While in this field, he is also able to generate whole facets of reality such as people, landscapes, weapons and atmosphere. The field itself has an estimated range of around a 10-mile radius, in which he can do essentially anything to his enemies with absolute precision, regardless of his conscious effort.

The Phantom Ruby's augmented reality constructs are as powerful as their originals and Infinite is able to selectively remove their effects on reality in any way he chooses. When generating a star with which to incinerate the Resistance, Infinite withheld the sun's gravity and atmospheric range to avoid distorting the entire solar system. When generating replicas of Sonic's past enemies, he removed the personalities of the Shadow copies to make them unreasonable. Whether or not the synthetic Phantom Ruby is capable of creating fully sentient copies or if it merely creates proxies of the original being is unclear. The copies are capable of existing outside of the Ruby Mist field, but they disintegrate if they lose consciousness. Despite having never met Zavok, the Phantom Ruby was able to perfectly replicate his appearance, powers, and personality to the point where Sonic thought he was fighting the original.

At base, the Phantom Ruby's power generates a thin force field around him that can deflect bullets and allow him to fly. Though he does not take advantage of this ability: by placing Ruby Mist clouds in various locations, Infinite is able to teleport by passing through them.

The Phantom Ruby under his control, while powerful, is not stronger than the original. The original is able to fully control its augmented reality with a minimum 50-mile radius. To make up for the glaring flaw of being forced to have the original in-hand, the synthetic Phantom Ruby is designed to be smaller and hands-free. However, the synthetic Phantom Ruby does not generate its own power, requiring an external reactor to maintain the strength and stability of its augmented reality.

"Powers" Debate

Due to translation errors and conflicting ideas in narrative structure, the Phantom Ruby and thus Infinite's powers are labelled as "virtual reality" despite having effects on the real world, which would be called "augmented reality". However, a lack of explanation on the Phantom Ruby's origin and full capabilities makes it entirely possible that the Phantom Ruby is connected to a form of the virtual realm that has yet to be explored.

Evidence of the Phantom Ruby's power being based in augmented reality

Infinite is capable of generating "illusions" that function in real time and have mass. According to Tails and Dr. Eggman, the Phantom Ruby causes a being to experience and show real pain including lacerations and burns. Psychosomatic injuries are not capable of showing burns or signs of external damage; at the very worst the only signs of injury would be internal bleeding from strained muscles or organ failure due to brain trauma. Infinite is also capable of affecting gravity and Ruby Mist clouds cause beings to teleport. Assuming that these abilities are not generated directly by the Phantom Ruby's source of energy, they would be otherwise impossible to perfectly simulate using virtual reality.

Evidence of the Phantom Ruby's power being based on virtual reality

There has been no conclusive evidence that injuries and death inflicted by the Phantom Ruby do not just appear as injuries, nor has there been any evidence that any virtual reality construct created by the Phantom Ruby is given illusory mass by the brain's reactions. It could merely be that the psychosomatic trauma is given as illusionary overcoat to further the fact that the Phantom Ruby is a weapon, and the illusions it creates do not wear off after a victim dies. Otherwise, it is possible that the Phantom Ruby is somehow capable of tricking the brain into inflicting real burns and lacerations on the body as a reaction to the illusions. As for the simulations of gravity, it is possible that the Phantom Ruby can trick the brain into thinking gravity is altered while removing any sensations that would indicate being on the ground.

Viewing the nature of the Phantom Ruby's power as a whole, the former is more likely due to the explanations given in-game and the terminology may have simply been lost in translation.

Eggman: Hey, you! I know you can hear me! You're captain of Squad Jackal, aren't you!? Your squad was useless! Go clean up their mess already!
Infinite: Yeah, yeah, I got it...
~ The Jackal accepting Eggman's order to deal with Shadow after his squad was eliminated.
You... You destroyed my squad. I'll show you why they call me the ultimate Mercenary! Take THIS!
~ The Jackal attempting to fight Shadow.
I... I'm shaking... Me!? Me... Afraid...!? Urgh. Pathetic!? Me... he's calling ME weak!? No! I am not weak! I'm... I'm not. I'm not weak! I AM NOT WEEEEAAAAAAK! URRRAAAAAAAAAAAGH!!!
~ Infinite's villainous breakdown after he loses in his battle against Shadow, prior to his transformation; his most infamous line.
Heh... You are spirited. I'll give you that. Very well. My new power will be the last thing you see!
~ Infinite confronting E-123 Omega
(cackling) The World's most powerful robot is no more a challenge than Crabmeat. As I suspected, this power is without peer... IT IS THE ULTIMATE STRENGTH! Ah, and still more wonderful, a not-so tall, dark, and brooding guest has arrived. I've been waiting for you, Shadow.
~ Infinite's first words when defeating E-123 Omega and meeting Shadow again.
(cackling maniacally) Ah, I suppose you would think so. Ohohoh yes. I am Infinite. You say you do not know me, and yet, I remember you so very well. To you, it was simply another in a long list of Eggman bases you tore down without a second thought.
~ Infinite thinking Shadow doesn't know him.
I've only become what I am because of you, yet you don't remember. But I suppose that's the way it goes. It simply means that the old me was too weak, too pathetic to remember. And now, you've become nothing more than an insect waiting to be crushed underfoot. Thanks to this limitless power I've obtained, I have become unstoppable! TAKE THIS!!
~ Infinite trapping Shadow in an illusion.
This is reality, Shadow. YOUR reality. I didn't expect to see you come back alive, but you must admit. It was a truly wonderful show, wasn't it?! [cackling] Oh, this power... before we've even tuned it! Just as I thought... IT IS UNRIVALED! NOT EVEN SONIC WILL BE ABLE TO STAND AGAINST ME NOW!!!
~ Infinite, planning to destroy Sonic, after Shadow escaped the Virtual Reality zone.
This wasn't part of my agenda, but I'm always happy to crush a hero. It keeps the rabble in line. Shows them that there is no hope.
~ Infinite facing Silver the Hedgehog.
Seeing is believing.
~ Reply to Silver before finishing him off.
Well, look who's back from the dead. The little blue savior. But what's that I smell? You reek of fear. Glad to see I left an impression.
~ Infinite encountering Sonic for the second time.
Your insistence is futile!
~ Infinite's brief Star Trek Reference, when Sonic tried to let him share his power's secret with Sonic.
Still thrashing around, I see, you filthy, little sewer rat!
~ Infinite in his first clash with Sonic.
~ Infinite
I will teach you to hold that tongue next time we meet. You can count on it.
~ Infinite defeated only by Sonic in the Mystic Jungle.
And with that, the disposal of the Phantom Ruby prototypes is complete.
~ Destroying the Phantom Ruby prototypes.
...nothing. We move on to the plan?
~ Infinite ignoring something he heard.
And the Resistance will yield to the Phantom Ruby's power. All will submit.
~ Infinite to Dr. Eggman.
More ants to crush. I wonder if this world can offer me a real challenge. And as if to answer, the world sends me a trembling child. Are you going to fight and die here, or run away in fear again?
~ Infinite meeting the player's avatar again.
Fine, I will teach you fear, then pain. And then...well, at least the fear and pain will end.
~ Infinite to the player's avatar.
You must be a straggler who got left behind. The strong will always vanquish the weak. You have only your own frailty to blame.
I remember you. You ran from me before, you survived then, but you throw it all away now. Curious. This will be goodbye.
~ Infinite thinking he remembers the player's Avatar before.
I've been looking forward to finishing you and your annoying friends. I trust you're all ready for oblivion? If you're not...oh well.
~ Infinite starting his final showdown with Sonic.
WHAT?! Who dares!?
~ Infinite meeting E-123 Omega again.
Is there no end to these annoying insects? I will burn your resistance to ashes and you along with it.
~ Infinite preparing to finish off the Resistance army.
Make peace with your fate. Because your lives are now over.
~ Infinite about to kill the Resistance members.
Pathetic little hedgehog. Even with the Phantom Ruby weakened, I still have enough power to smash you into blue jelly. I'll show you how outclassed you really are!
~ Infinite before he battles Sonic for the final time.
Perish along with your useless friends!
~ Infinite
No, wait! I can still fight!
~ Infinite's last words before disappearing after Sonic and the Avatar defeated him.

Theme Sample


  • Infinite's face is never seen in the game itself, nor the "Episode Shadow" prequel. However, it is shown in the prequel comics.
  • His English voice actor, Liam O'Brien, also voices Zazz, another Sonic villain.
  • Following his boss battle, Infinite fades away and vanishes, against his own will. It is unknown whether Eggman forcefully teleported him away or if the Phantom Ruby deemed him unworthy and possibly erased him from existence, allowing Eggman to harness its power for his Death Egg Robot.
  • It is strange that Infinite is not attacking Shadow directly in the main game since he hates him well before he meets Sonic. It is also unexplained why Shadow is one of the counterfeit villains Infinite produces if he hates Shadow.
  • Infinite is considered by fans to be one of the evilest villains in the Sonic the Hedgehog franchise alongside Mephiles the Dark (who was also both Iblis and Solaris, his true form), Black Doom, and Erazor Djinn.
  • Infinite is one of the very few antagonists in the franchise who works with Dr. Eggman without betraying him for his own personal agenda, alongside the Time Eater. Unlike Time Eater, Infinite was not brainwashed and had far bigger plans and was far more threatening than Time Eater itself.
  • According to Sonic, Infinite reminds him of the evil genie Erazor Djinn. He was the second villain who called Sonic a rat (the first being was Erazor).
  • Because of the "edgy" (a term used for something that is overly dark) nature of Infinite's character, a lot of people have made fun of the character, even to the point of it becoming a bit of a meme.
    • In addition to this, Infinite is often compared to certain Sonic "OCs" (Original Characters), where they are portrayed as powerful beings with a dark history/nature, mainly due to his design as well.
  • It's possible that Infinite could return in future games as his fate is never specified and the Phantom Ruby is still shown to be active in the Encore mode of Sonic Mania Plus which takes place right after Sonic Forces.
    • Additionally, it's mentioned in the official Sonic the Hedgehog Encyclo-speed-ia written by Ian Flynn that Infinite was "consumed" by the original Phantom Ruby after his defeat, implying he was imprisoned within it and currently resides inside, or was truly killed off by the ruby itself. Nevertheless, the book's vague phrasing has led to a divide between fans, with many speculating the wording of "consumed" was intentional in case Sega wanted to bring Infinite back in the future.
    • If Infinite is indeed trapped within the Phantom Ruby itself, it's possible that he's now in control of it, which would make him the overarching antagonist of Sonic Mania Plus.
      • With the reveal of the new character Sage for Sonic Frontiers, a similarly red glitchy character, it remains to be seen if Infinite will return. It's possible that he may serve as Sage's henchman or the true hidden big bad of the game.
  • Infinite has fought all three members of the Hedgehog trio, Sonic, Shadow, and Silver. He first fought Shadow, who drove him into becoming who he is now. Then Sonic, whom he defeated very easily during their first encounter but was later defeated by him in their final battle. And Silver, only a brief clash but seemingly defeated Silver easily nonetheless.
  • Despite not being the main antagonist, Infinite had more screentime than his boss, as he was the one who drove the plot, committed all of the mass murders and led the attacks on many cities. Plus Infinite is fought three times, while Eggman is fought twice.
  • Infinite is also the very first villain to have Sonic fully defeated and it took months for Sonic to come back and fight like most villains do when they get defeated.
