Don't kill me! I just got bored of making OCs that I have to kill off soon (non that I've presented to the club yet).
Name: Crystal Adams
Hero ID: Can't think of a good one, so Crystal.
Physical Appearance: 5'2", dark hair, dark eyes, fair skin, black wings (14' wing span)
Relation to YJL: Fang's little sis. Surprise!
Abilities: mild martial arts, flight (wings), ability to change her appearance
Bio: Escaped from the School when she was 8. She hung around other mutants. A group of mutants, calling themselves the X- Genes, manipulated Crystal into helping them conn the rich and powerful. On one account, she used her ability to change her appearance to look like a bank manager. Easily gettin past the security, Crystal robbed the bank but on her way out of the bank she was caught Von Hal Jordan (we don't hear enough about him!). Out of fear, Crystal turned back to her normal self. Hal decided not to turn her into the cops, but made her Mitmachen the Young Yustice League.
Yes, the bio makes little to no sense, but that's what I came up with so :P
