Zenoheld

Zenoheld was the main antagonist of Bakugan Battle Brawlers: New Vestroia, although he didn't become personally involved until the second arc. He was the former King of Vestal and the father of Prince Hydron. He used a Mechanical Bakugan called Pyrus Farbros, made by Professor Clay. At the end of New Vestroia, he is killed by the Alternative Weapon System's explosion along with his estranged son Hydron and Professor Clay. (Source: Bakugan Wiki)
