Zombie Virus

Zombie Virus is the Quirk of Romero Fujimi.

Description
The Quirk enables Romero to produce a pinkish gas that, when inhaled, transforms victims into zombies. Those infected gain the endurance of a zombie and the ability to pass along the virus via bite. If a hero is infected by the gas, they can use their Quirks. They also say "AHHH!" a lot.

The only weakness to this Quirk is that user is not immune to it. An example of this is when Romero is bitten by an infected Katsuki Bakugo, resulting in Romero turning into a zombie.

Also, anyone who has a zombie-like appearance will be seen to the zombies as one of their own. An example of this is when Toshinori Yagi deactivates One For All, the zombie heroes leave him be, believing that he is one of them.
