I knew it! Black can use all three atributes! And he is the opposite to white. Black can toughen his body up, manipulate air and uses a hula hoop as a weapon while White can fly/levitate, manipulate earth and uses a katana. Now I want to see them both fighting against each other as soon as Black discovered his full potential! But there is no need to rush this, let him fight the other two guys first, followed by him finding a way to get up to the masters place.
