Zenoheld
Zenoheld was a brilliant scientist who created the Bakugan Interspace system. He was also the father of Ren Krawler and Mira Clay. However, he was also a power-hungry tyrant who wanted to control all of Vestroia. He used his Bakugan, Razenoid, to destroy the Great Core and take control of the Bakugan Battle Brawlers. He was eventually defeated by Dan Kuso and the other Brawlers, and was imprisoned in the Doom Dimension.
