Super Hero Gnar
We already have super hero teemo. The galatic rumble is kind of a hero as well. Now image little gnar in a suit, he can even throw breif cases or something of the mild manner nature, When he turns he clothes rip off and underneath is a super hero costume. You could literally have both his alter egos in the same skin. For the artwork he could be ripping off shirt a little to show a G underneath and his shadow could be big and clearly have a cap flapping off of it. I don't know exactly what he would throw in his super hero form. But on top of this you can make gnar say cute super hero sayings when he turns and make him mess them up.
