Bari was a mamodo who existed without a purpose. It infuriated him that he had no real goal in life, and this spurred him to constantly engage in violent battles with other mamodos. In these battles, he often didn't care who got hurt, so long as he could become stronger. This led to the harm of innocent people.
Powers and Abilities
Bari primarily fought using his fists, but his ultimate spell involved blasting the opponent with a purple cyclone.
After learning that he wanted to become the strongest mamodo king ever known, his violent streak comes to a halt, as the realization of purpose in his life gave him peace. He, eventually, wound up sacrificing himself to allow his allies to continue a battle.
