Maybe Kha'zix can evolve into the point where he becomes the most powerfull being in the phisical plane, but xerath can bypass that problem once he gets out of his coffin, and the same goes for brand, ofc, malzahar can also become the most powerfull being by default, because he can summon the void, and no one really knows what lurks in there.
