Akira Iwako ( (いわ) (こう) (あきら) Iwakō Akira?) was one of the Instant Villains.


Akira was a middle-sized man with curly black hair.


Akira was only ever seen while he was under the influence of the drug Trigger.

When he was seen, however, he was incredibly aggressive to essentially everything that was around him, attacking buildings and civilians. He was very confident in his abilities, believing himself to be totally indestructible and undefeatable.

However, he was capable of showing some sort of sanity, as he fled from Stendhal when he realized that he was outclassed. He was also capable of displaying fear when he realized he was in danger.

He was also one of the few villains to remember Koichi Haimawari’s vigilante name as "The Crawler".


Vigilantes Beginnings Arc

Akira defeated.

Akira is defeated by Knuckleduster and The Crawler after going into a rampage while on Trigger. He is released on account of being a simple Instant Villain, making him a victim and not a real criminal.

Stendhal Arc

He fights Koichi later in another rampage, but this time he is confronted by Stendhal, being brutally killed by the vigilante.


Akira uses Hardening while on Trigger.

Hardening: Akira's Hardening Quirk is only ever seen under the effects of Trigger. Once he gains a power boost from Trigger, this granted Akira the ability to grow rocks from his upper body, as well as make him bigger and stronger.[2]
