Brron, Mad King of Dark World (character)

Brron, Mad King of Dark World serves as the main antagonist of the Dark World arc (episodes 133-136) of season three. He makes his first actual appearance in episode 135 when Jaden travels to his stronghold. In the Japanese anime, he's voiced by Kentarou Itou.

Demented and sadistic, Brron rules the alternate dimension as its vile dictator. Although his role in the anime is brief, his actions are vital in Jaden Yuki's transformation into the Supreme King of the alternate dimension.

Character biography
Being the leader of the Dark World creatures, he is responsible for the deplorable state of the second alternate dimension and oppression of its denizens. His right-hand man, Zure, Knight of Dark World, oversees Brron's will, detaining anyone who defies him in internment camps while killing duelists who could be possible threats to him. The executions occur at his fortress and involve releasing monsters at disarmed duelists while Brron himself and his minions watch the spectacle. After learning of Jaden's presence in his domain, Brron orchestrates a plot that involves turning Jaden evil.

Due to an underhanded manuever by his top subordinate, Zure, Knight of Dark World, Brron has a clear advantage with his set of Wicked Doctrine cards because should one of them be activated, one of Jaden's friends would be sacrificed. Eventually Jaden defeats Brron in a fit of rage, but not before Alexis, Chazz, Atticus and Tyranno are all sacrificed. Only Syrus manages to avoid being sacrificed. After his defeat, he simply mocks Jaden before dying. It is later revealed that Brron was simply one of Yubel's pawns, who used him to complete the integral part for its plan, the creation of the ''Super Fusion card, and to simaltaneously cause Jaden to descend into darkness.

Deck
Brron plays a Dark World Deck, evil creatures whose latent abilities are activated when they are discarded by a card effect. He mainly focused on the gathering of the Wicked Doctrine cards which grants Brron access to his most powerful monster, Colorless, Chaos King of Dark World, summoned through the card, Super Fusion, although the Colorless card is not actually seen. If the aforementioned strategy fails, Brron focuses on the summoning and preservation of Reign-Beaux, Overlord of Dark World, which has the ability to destroy his opponent's Monster cards or Spell and Trap cards.
