Parasitic Modifications
Main Ability
Grants the user the ability to modify their body in any way they wish. From the enlargement of their physical size to the creation of new limbs, everything deriving from the realm of physiology is modifiable. Alongside it's limitless creative potential, all physical capabilities such as strength, speed, endurance and stamina are greatly enhanced due to this. It also comes with the added bonuses of a seemingly impervious immune system, night vision, enhanced hearing and proficient regeneration
Secondary Ability
The consumption of the sufficient amount of blood deriving from a specific being allows the user to shapeshift themselves into a physical replica of the originator. However, the shapeshifted form is still incapable of replicating the "quirks" of others, it is merely a physical replica that holds the same looks and voice as the originator. Even then, all parasitic bodily functions still exist in this state, thus making up for this disability
(SPOILER: Just so you know, Black has a "quirk" that allows him to bypass the need to consume blood in order to shapeshift. I'm not gonna tell you who's quirk it is (although I'm pretty sure that you already know who) but all I'm gonna say is that alot is going to change with the next chapter release. Chapters are getting rewritten with new lore, abilities are going to get clearer explanations, other characters are gonna get some time in the spotlight, and alot more. This overhaul may take months, but I promise you that it'll be worth it)
