Awakened Cockroach (覚醒ゴキブリ, Kakusei Gokiburi, Viz: Roach Awakening) was a Demon-level Mysterious Being and a member of the Monster Association.


Awakened Cockroach was a humanoid cockroach with a dark-colored carapace and a human face. He had six arms and long antennae.


Awakened Cockroach is very confident in his abilities, particularly his speed. He prefers targeting heroes in contrast to other monsters. Awakened Cockroach does not seem to kill heroes, but rather focuses on incapacitating them and then letting other monsters finish them off.[1] He occasionally humors himself during battle.[2]

Genos vs. Awakened Cockroach

Awakened Cockroach fights toe-to-toe with Genos in hand-to-hand combat.

Awakened Cockroach attacks C-City as part of the organized strikes against the human cities. He defeats 3 heroes with apparent ease and encounters Genos, warning him that he is strong.[3]

During the fight with Genos, Awakened Cockroach maintains superiority, blocking or dodging every attack by Genos, while sending out his own attacks, outmaneuvering the cyborg with his speed and tricky movements. Awakened Cockroach has the upper hand until Genos decides to use instant adhesive to trap the monster, which was originally meant for use against speedster villains like Speed-o'-Sound Sonic. However, before Genos could kill the monster, Awakened Cockroach sacrifices his feet to get away.[4]

Orochi eats Awakened Cockroach

Awakened Cockroach is about to be devoured by Orochi for his failure

After his battle with Genos, Awakened Cockroach goes to the Monster Association Headquarters in order to partake in a meeting that the monsters were having. During the meeting, Orochi impales Awakened Cockroach with one of his horns after realizing that he lost a battle prior to the meeting. Despite begging for mercy and asking other monsters to save him, Awakened Cockroach is devoured and killed by the Monster King while the other monsters watch in horror. [5]

Abilities and Powers

As a Demon-level Mysterious Being of the Monster Association, Awakened Cockroach is an extremely powerful being, having defeated three heroes with apparent ease, although the heroes were rather weak. However, he was utterly powerless against Orochi, and was easily defeated and subsequently consumed by the Monster King.

Physical Abilities

Awakened Cockroach Movement

Immense Speed and Reflexes: Awakened Cockroach possesses an incredible amount of speed and sharp reflexes, being able to fight on par with Genos, a powerful S-Class Hero with immense speed who just received his G4 upgrades.

Immense Strength: As a demon-level mysterious being, Awakened Cockroach is very strong. He is able to damage Genos with his G4 upgrades quite a bit during their fight.

Cockroach Traits: True to his title, Awakened Cockroach possesses many of the natural traits of a cockroach. This includes having six separate arms, giving him a natural advantage in close combat, and the ability to survive with important body parts missing and regrow them later. He used the latter to escape Genos' Incineration Cannons, breaking off his own trapped feet in order to escape and later reappearing with his feet fully intact.

Heightened Senses: Awakened Cockroach's senses are far beyond the norm. According to him, even if his opponent could attack at the speed of light, they still would not be able to hit him because his body developed a sixth sense; being able to sense killing intent and dodges attacks on its own in advance.[6] However, this is most likely a boast, because he was unable to dodge Orochi's attack.

Fighting Style

Expert Hand-to-Hand Combatant: Awakened Cockroach has shown to be on par with S-Class heroes when it comes to close quarters combat.[7] He tries to be unpredictable in his movement, moving erratically during his fight with Genos. His unique footwork keeps him outside the field of view of his foes, with even Genos' advanced sensory systems being unable to properly track him. He uses his surroundings to break his opponent's line of sight.[8]
