Quirks starting with A

Animagus: This quirk allows the user to alter their appearance and facial features to look like to those of an animal. The transformation is parted in three categories which reflect in the user's eyes. Land, sky, water.
Physical touch is required to copy an animal's cells and give the ability to the user to change their features.(example: must have pet a dog to alter your features to one)(branch of the quirk)

Arcade: This quirk gives access to video game skills and power ups. A health bar will appear above fighters' heads. Although strong, the quirk can easily glitch, show errors or be eliminated by water and electric quirks. 

Alphabet: This quirk gives access to every language that is or used to be spoken in existence.

Aroma: This quirk causes the user's skin pores to release aroma, depending on their emotions. Sometimes the aroma can be controlled by the user themselves.
