Akuma is a character from the Street Fighter video games. He has a notable appearance in the StrikeForce Kitty series.
StrikeForce Kitty: Last Stand
It is obtained by having its own "New Clothes" event after said raccoon is defeated. Once the cosplay is acquired, it can be found on the second-to-last hanger of page 9 of the "Melee" category, beside the trophy costume.
The passive ability is always the same: the cat wearing this cosplay has a 40% chance to freezing an enemy for 8 seconds.
Note: If the second-to-last and last hangers are a different cosplay sets instead of this and the trophy costume, then it is a bug.
StrikeForce Kitty League
Akuma retuns as a cosplay in StrikeForce Kitty League. It can be obtained by defeating Internazionale Foxano a few times in the Shark Division until the costume is acquired or by buying it by chance at the store for 3000 fishes.
The active cosplay ability is unique: once successfully activated, the other team members have their cosplay abilities out of cooldown (if still cooling down), ready to be used sooner.
