Rest in peace, Whisper. It was fun while it lasted.
~ Mimic assuming his victory over Whisper.
They weren't my friends. They weren't even my comrades. They were a means to an end. I was in it to reap the rewards. When their big crusade put my life on the line, it wasn't a difficult choice. Heroes become martyrs. Professionals stay alive.
~ Mimic showing no remorse for his treachery.
So long, fellas. It's been fun. But now I'm free to go pay Whisper a visit.
~ Mimic betraying Starline's team.

Mimic the Octopus is a villain in the Sonic the Hedgehog IDW comics, appearing as the main antagonist of the Tangle and Whisper storyline. He was once a trusted member of the Diamond Cutters before betraying them to Dr. Eggman, and is now the archenemy to Whisper the Wolf.



When in his true form, Mimic appears as an anthropomorphic octopus with purple skin, a beak-like mouth, black eyes with white pupils, suction-cups on his hands and feet and tentacles for hair. His beak has wrinkles around the lips and what looks like a nasal bone on top of it. He wears a black, tattered poncho and coverings on his arms and legs.

Whenever in disguise as someone-else, Mimic's pupils are always brown, but sometimes he shows his real eyes as well as the wrinkles on his lips. He also always retains his suction cups on his hands and feet. However, no-one seems to notice these traits whenever they see him in disguise.

While Mimic was still working with the Diamond Cutters, his poncho was much nicer and and he wore black gloves and boots, but didn't have the nasal bone or the lip wrinkles at the time. He also had a mask similar to Whisper's until he betrayed the team.


When working with his former team, Mimic put on a facade of a loyal and trust-worthy comrade. In reality, though, he was a greedy and cowardly individual who only looked out for himself and did not think twice about betraying his team to save his own life, even willing to end one of them himself if it was required.

In the present, Mimic maintained his treacherous nature, using his mastery of disguise to manipulate people into doing whatever he wanted. He's also become obsessed with ending Whisper's life in order to save his own, and still has no remorse for what he did to his former comrades while viewing friendship as a liability. Mimic has also shown a great sense of pride, regretting that both Whisper and Tangle defeated him and left him to rot in prison instead of killing him.

Ironically, Mimic despises being betrayed himself and doesn't trust anybody. If he learns that someone he was working with planned to double-cross them, he will immediately attempt to kill them unless given a good reason not to.

Powers and Abilities

Mimic has the ability to instantly disguise himself as different people, including Sonic the Hedgehog and an Egg Pawn, and was quite good at impersonating them. He could even alter these forms somewhat to for added convincing if need be, such as making clothes look torn. However, he could not replicate the skills of the people he changed into, such as Sonic's speed. He also had impressive combat skills and usually fought with a knife, along with some other weapons such as guns or bombs, and was a master of escape artistry.

He once wielded a hammer-like Wispon designed by Smithy that utilized a blue Wisp to create solid blocks that he and his teammates can use as stepping stones. However, he abandoned it after his Wisp abandoned him.

During the raid on the Eggman hub, Mimic utilized a device that was powered by Yellow Power Cores, granting him increased agility and flight.



Mimic was once a member of the Diamond Cutters, a secret mercenary team dedicated to fighting against the Eggman Empire, alongside Slinger the Ocelot, Smithy the Lion, Claire-Voyance the Howler Monkey and Whisper the Wolf, all of whom resided in a secret base in the middle of the Clove Sea. Each of them carried a specialized Wispon designed by Smithy and were partnered with a Wisp to use said Wispon, which in Mimic's case was a hammer that could create blocks powered by a Blue Wisp. Mimic's infiltration skills proved quite useful in sneaking into Eggman's bases and destroying them from the inside, and the other Diamond Cutters came to trust him with their very lives. Unbeknownst to them, however, Mimic was only in the group in order to gain profit from their missions and saw his trusting friends as nothing more than a means to this end.

At some point near the beginning of the Eggman War, the job became too difficult for Mimic to bear, and so he secretly cut a deal with Eggman to betray the Diamond Cutters in exchange for sparing his life. He then led the team into one of Eggman's bases which they planned to destroy in the hope of disabling his forces along the coastline, but only Slinger, Smithy and Claire followed him inside while Whisper remained outside as usual per Claire's suggestion. Once inside, Mimic pretends to separate from the group to scout ahead, but in reality was abandoning them to be trapped in a room filled with Shadow Androids that quickly overwhelmed and eventually killed them while he met with Dr. Eggman himself in a secret room. Eggman was impressed by Mimic's treachery and agreed to pardon him for his "crimes" against him, but his Wisp, disgusted by his heinous action, abandons him, though he felt nothing about it. When Eggman learned that Whisper was not among the casualties, Mimic tried to explain that she was no real threat to him, only to be ordered to eliminate her immediately or face the consequences. Reaching Whisper's location, he attempted to fool her by pretending to be Slinger, but only finds her Wispon laying on the ground and concludes that she had run off when the plan went awry. Fearing Eggman's wrath, Mimic decides to use her Wispon and his own mask, which was identical to hers, as proof of her demise, believing her to be too cowardly to be a threat without her weapon or anyone-else to support her. He then walks away from the area singing to himself, unaware that Whisper and her Orange Wisp were actually watching him while quietly hiding atop a tree branch.

It is unknown what Mimic was doing during the final days of the war. Likely, he went into hiding out of fear of getting killed in the war or by Eggman personally if he found out he was lied to.

Tangle and Whisper

Issue #1

After the events in Sonic Forces, Eggman (upon regaining his memories) learns that not only was Whisper was alive, but was a significant threat to him during the war. Though enraged that Mimic had lied to him, Eggman gives him a chance to finish what he was ordered to do before or else. To lure Whisper out, Mimic then disguises himself as Sonic and begins committing crimes all over, such as painting graffiti Eggman symbols, abusing Chao and literally stealing candy from babies. Suspicious about this, Whisper investigates into this and eventually finds "Sonic", who continues the facade before attempting to kill Whisper with his knife. However, Whisper anticipated this and forces Mimic, who was still disguised as Sonic, on the run.

Whisper chases Mimic into Spiral Hill Village, where Whisper's friend, Tangle the Lemur resides. Using Sonic's appearance to fool the public, he uses a passing civilian woman as an unsuspecting meat shield, forcing Whisper to change her position of fire when trying to snipe him from a rooftop. He was then able to escape into an alleyway where he encounters Tangle, who demands to know why "Sonic" isn't running at full speed and why Whisper is chasing him. Sensing an opportunity, "Sonic" lies to Tangle that Whisper was being mind-controlled by Eggman using a chip in her mask, which the lemur falls for, and also advises her to attack first and ask questions later As she leaves "Sonic" to recover from running, Whisper attempts to snipe him from a rooftop, but Mimic gives her a smug look with his real eyes, which confuses her and leaves her open for Tangle to tackle her. As they fought, this allows Mimic to escape unnoticed. After the fight, Whisper shows Tangle the truth using footage from her mask. Then they then both travel to the local museum to compare notes while Mimic looks on, taking the guise of a civilian that he used as a living shield.

While still in guise, Mimic observed through a museum window as Whisper explained to Tangle and her other friend, Jewel the Beetle about who Mimic is. He then pinned a knife on the museum door with a note that said, "We've chased each other in circles long enough. I'll be waiting for you the settle things once and for all". Below the message was some coordinates to where he was waiting for her.

Issue #2

Tangle and Whisper arrive at an abandoned Eggman Empire bunker, where Mimic was hiding out. Upon spotting the duo through a window, he remarks that while Whisper had become formidable with their old team's Wisps, she was never capable of working alone. He then decides to take advantage of Tangle's gullibility again by morphing into her friend, Jewel the Beetle.

Using Jewel's voice, Mimic attracts Tangle to his location. Then he takes on Whisper's appearance and leads Tangle into a vault where he traps her inside. He then morphs into Tangle and manages to convince Whisper by making her shirt look damaged, and then leads her into another trap with an Egg Hammer, which she promptly destroys. Mimic tries to finish her using bombs and a pistol, but fails. Whisper then uses the Blue Wisp power to threaten Mimic to tell her where the real Tangle is, but then Mimic attempts to manipulate her by transforming into Slinger, Claire and Smithy while remarking how she failed to protect the team. In response, however, Whisper strikes and reminds him that he was the one who betrayed them, and that she will be the one to avenge their comrades. Mimic then reveals where Tangle is and dares Whisper to try to save her and escape before the bombs he set destroy the whole bunker. As Whisper goes to save Tangle, Mimic exits the bunker and locks the door behind him. He then walks away in his real form, saying good-bye to his old friend-turned enemy.

Unfortunately for him, his plan to kill Whisper fails as Tangle uses the safe she was trapped in to shield them both from the blast.

Issue #3

After surviving Mimic's trap, Whisper shows Tangle the video footage of how she and Mimic worked together alongside the other Diamond Cutters until he betrayed them scarred her for life, making the lemur more determined to help her bring him to justice for his crimes. Knowing that Eggman won't accept faulty evidence a second time, she comes up with a plan to lead Mimic into a trap of their own.

The next morning, Mimic is forced by Eggman to return to the site of the explosion to search for solid proof of Tangle and Whisper's demise, or else be hunted by Metal Sonic. After some searching, Mimic finds an open safe that endured the explosion, showing that the duo had survived his trap. He also finds deliberate footprints leading him to a message drawn in the sand, stating: "WE END THIS WHERE WE STARTED". Knowing exactly what the message meant, he then asks Eggman to loan him some back-up.

Issue #4

At the old Diamond Cutters' base, Whisper and Tangle wait for Mimic to arrive, but find an army of Badniks heading towards them instead. While Whisper deals with the robots, Tangle goes inside and suddenly finds "Sonic", who claims that he arrived thanks to Tails. Tangle then leads "Sonic" to the trap they set up for Mimic, but "Sonic" is confused to find only a rec room with the deceased Diamond Cutters' masks hanging on the wall. Tangle then reveals that she wasn't fooled by Mimic's impersonation and springs the trap, which involved showing him old holograms of his old teammates giving him compliments and showing their trust in him in an attempt to mess him up like he did Whisper. Unfortunately, the trick had absolutely no affect on Mimic, who reveals that he never had any affection towards his old team in the first place and was only in it to benefit himself, which is why it wasn't a hard decision to betray them to Eggman.

After hearing this, Tangle becomes enraged and prepares to attack him, but Mimic morphs into Jewel, causing her to hesitate. After goading her to hit him anyway, he trips her up and prepares to finish her with his knife while gloating about taking her form to finish Whisper as well. However, Tangle hits him in the back with her tail, with Mimic calling her out for using such a cheap shot and Tangle stating that it was a "taste of his own medicine". They fight, but Mimic's superior combat skills enable him to get the upper hand. He grabs his knife and attempts to kill Tangle, but Whisper arrives to save her by bludgeoning him with his own former Wisp. Mimic then manipulates his old Wisp by reminding him of how he always hated violence, causing it to relent, but Whisper hits him with her Wispon anyway. Mimic was able to wrestle the Wispon away from her and then attempts to shoot her with it, but Tangle wraps her tail around him and swings him unto a table, breaking it. Mimic screams that he can't lose like this and attempts tries him to surrender or else she'll squeeze him harder. After he finally submits, Whisper then prepares to execute him for all that he had done, but Tangle talks her out of it by stating that killing him wouldn't be the right choice and that letting him live with the shame of losing to them would be even worse than death. After much thought while looking at her old teammates' masks, she agrees with Tangle that the Diamond Cutters have been officially avenged, and comforts the Blue Wisp by saying that she doesn't blame it for relenting to attack its former partner.

They then take Mimic to Tails' workshop, where they entrap Mimic inside a specialized chamber that even he can't escape from. When Mimic boasts that he will eventually escape, Whisper vows to stop him if he does, and Mimic taunts her about how their teammates would react to her new attitude. But then Tangle insists that he should stay, stating that it would be the safest place from Eggman, whose robots Mimic wasted in his failed attack on them. Unable to argue with this logic, Mimic expresses his utter hatred of the lemur. Tails then promises to have the chamber transported to the nearest prison, with Whisper and Tangle making him promise not to open it no matter who he sees is inside it.

Bad Guys

Mimic is set to appear in the Bad Guys mini-series as part of a team put together by Dr. Starline alongside Rough, Tumble and Zavok.


  • Mimic is based off of the mimic octopus, which can camaflouge itself with the environment and impersonate other species, which fits Mimic's abilities and profession.
  • Like all the members of the Diamond Cutters, Mimic is based off one of the main operatives of FOXHOUND in the Metal Gear series. In Mimic's case, he is based on Decoy Octopus, who he shared his mastery of disguise and animal theme with.
