Human Monster SagaEdit
Monster Raid ArcEdit
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. 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.
Monster Association ArcEdit
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, Awakened Cockroach is devoured and killed by the Monster King.
