[@Nomadic] Currently toying around with a couple character ideas.

1.
Male character.
Quirk: Glutton - He has insanely strong stomach acid and the ability to open his mouth incredibly wide with a very strong bite. He is able to bite through most things and digest basically anything. 
Notes: He has a horrifying mouth and is often hidden behind a half mask that covers his mouth.
Constantly perceived as a villain because of his appearance he has a strong desire to prove everyones assumptions wrong.

2.
Female Character.
Quirk: Undeath - She is technically not alive or dead. Her body can withstand any damage. She can re-attach any piece of her that may have been removed and even regenerate slowly over time. Only fully killed if she is completely disintegrated. 
Notes: Since she does not have a living body the removal of her quirk would kill her.
She has no notable (super human) fighting capabilities. She would need to work with Support Items to be combat capable or used as a "Meat Shield".

EDIT: Was thinking of giving Second character maybe some improved strength. Given her more or less dead body she isn't restrained by your standard humans Muscle and tendon strain.
