Deku:
Quirk(s):
One For All- allows the user to stockpile an enormous amount of raw power, allowing them to significantly enhance all of their physical abilities to a superhuman level. This results in unbelievable levels of strength, speed, agility, and durability. ( In his Full Cowling state, instead of green electricity it will be whitish silver)
Arctic Fox- allows the user to do anything an arctic fox can, but better. It gives the user sharp canine teeth, a keen sense of smell, enhanced hearing, etc. User will also have a coat of white fur covering their body that is invisible to the human eye.
If something were to anger the user like, for example, someone they care about dies, they will go into a feral state until they kill or knockout the person responsible, or if the user is rendered unconscious.
Looks:
Concerning looks, he will still look the same as canon but I will be changing his hair color from green to white. He will still have green eyes. He will have fox ears and a fox tail.
Miruko
The only thing I will change for Miruko is that her age will be dropped from 26 to 21.
