Supreme king jaden

The Supreme King (覇は王おう Haō) is the wielder of The Gentle Darkness and the alternate, darker personality of Jaden Yuki that possessed him while he was in the second alternate dimension searching for Jesse Anderson. He serves as the second main antagonist of the final third of season three after Brron and his Dark World Army are defeated, starting from episode 136 until his defeat in episode 143. According to Bastion Misawa (and later confirmed by Yubel herself), it was Yubel who orchestrated Jaden's awakening as the Supreme King, with the intent of ruling over the united twelve dimensions together.
