Hero Name: Super-Loli
Alter ego: Student council President
Powers: Someone replaced her appendix for a teleporter stone. You don't want to know how.
Enhanced body: Quite unimpressive superhuman strength, speed, reflexes, durability. It doesn't work against normal people. Deactivates when touching someone normal. It's very effective when used with her teleport ability but lackluster by itself.
Teleportation: 5 meters max. Can't be cancelled but doesn't teleport weapons or clothes, hers or from other people. It does work with biological beings but they also lose their clothes or inorganic stuff.

She's very prideful, serious and her sense of justice is probably unparalleled but she's also very inexperienced. She's not very useful against non super powered villains.
