There are enough Star Guardians

But if you still want to milk the anime school students who are also super heroes, how about Persona-style skins?

Annie, the sweet but secretly sadistic cute girl, already has Tibbers as her Persona, just put her in an edgy outfit. Shaco, the class clown but is hurting deep down and wants to hurt others, has his clone as an alternative personality Persona, Azir, the main protagonist since he can control multiple personas (soldiers, tower) Ivern, the stoner with Daisy as his Persona.

Edit: was too busy thinking about weed daddy Ivern to remember Yorick existing.
