To avoid stepping on people's toes I thought I'd put my quirk ideas up here. One is the ability to merge with shadows, dive into them and run along wherever they're cast kind of thing. Roll as a stealth hero with a possible focus on rescue ops if they're allowed to bring people in with them.

Or to imbue things with fire, elemental enchantment style. So say character is holding a pipe BOOM now it's a flaming pipe! They'd probably style themselves a mystic swordsman or flaming fist of justice type :p
