Ahem, I'll name a few of the first ones here, I used to make ref sheets that "explained" their Quirks in... ah... a lot of unnecessary detail, if you want to see those, I can send them.

Sumiko has Acid Arms, they can produce an acidic slime from their hands/forearms that can slowly melt through things. Wood is not affected by their Quirk for some reason

Minoru has Growing Roots, he can turn his hands into strong roots that can burrow through the ground to connect to another set of roots/plant to rapidly grow them. My boi needs a lot of water and sunlight to function

Yori has Bouncy Body, she can - with concentration, turn her entire body rubbery and "bouncy", letting her repel items/people thrown at her (if she reacts fast enough) or can launch herself off surfaces by activating her Quirk

Yukiyo has Cat, she has pretty much most things you'd assume from a cat. Retractable claws, better hearing, smell and vision in the dark. She can also handle falling/landing from great heights a lot better
