Okay it's information tiiiime.

Name: Specter Arc
Age: 21
Height: 5'8"
Ability: He has the ability to change from his normal height to size of a micro, but if he's being held or in that would restrict his normal height he won't be able to go back to normal size. When micro sized his body becomes more resistant to pain and pressure.

He also has a foot fetish and mouth play fetish.
He's a college student. He tends to be quiet and keeps to himself. He's shy at first until he gets comfortable with being around someone. He prefers to stay in his dorm and study most of the time or waste time playing video games.

Blah blah - I'll add more when I have my thoughts in order.
