He is a former Universal Champion. Since returning, he has mentioned many times that he wants to get Universal Championship which he never lost. That's his goal. Also, taking WWE beep booking about Bálor, he loves to stand up for fights. He doesn't let the wrong happen like standing up to Kane for trying to injure Jason Jordan. He doesn't care if his opponent is stronger or larger. He just doesn't back down from a fight. That's what a hero should do, no?
