Aster Gigen

Aster used to be a human as Levi, but after crashing into someone fleeing a hijacking with a case of vials, he accidentally cut himself on the glass while getting back up, continuing on his way to his apartment on his hoverboard, only to wake up as a fluffy alien noodle. After shorting out that he has a shape-shifting ability, he thinks of himself a bit more like a superhero vigilante, Though he's slowly dragged into a plot involving the weaponization of aspects of the artificial species he was turned into, all while adjusting to his new body and dealing with some of its quirks and also trying to keep his new identity as Aster separate from his human identity as Levi.
