There's a few things I'm confused about exactly.

In regards to her abilities how would consuming anything allow her to mold or change something? Wouldn't a consumption ability simply give her super human amounts of stamina? Likewise wouldn't her bite force be her main offensively viable option? The way it seems to be worded at the moment implies that she can have multiple super hero types? Maybe I could see consumption of things like concrete, metals, and the like give her harder skin as it takes the alloys found in them and transfers it to the skin but the ability to mold, change, or alter then sounds like very specific abilities that you would find in an entirely different quirk. Maybe toxic materials allow her to spit up wads of spit that can transfer the toxins into the bodies of other heroes as well but I'm not entirely sure the quirk would work the way you think it would. If you can convince FallenTrinity or I otherwise you're free to go ahead and argue your points however.


In regards to her history it sounds fine so far but it needs to be elaborated a little bit more on how you joined the JS. They're a rather big name group. Not as big as The Protector's Initiative, or BaB but you'd probably need a feat or a mentor hero to be a side kick under if you'd want to join them. Just for reference's sake you can have the option to just be a part of a generic agency, or not have one at all.
