Duema Land President

Duema Land President was first introduced in the Duel Masters Versus Revolution series of the Duel Masters Anime.

He leads the secret society of Duel Masters Land and seems to be the show's new antagonist.

Details
He wears a robotic costume, is able to manipulate electricity and his behavior and appearance seem vaguely reminiscent of Benny Haha. Also, from episode 24, it was revealed that he can consume up to a whole city worth of electricity to charge himself.

He also have no qualms to take a person's life in order to reach his goals, but unaware that someone had already make their move to end his plans.

History
Not much is known about his background other than the fact that he has recruited strong duelists such as Duemouse, Basara, Hakase and Rambo at some point in the past. He also has the possession of Forbidden (locked in its seal), one of the most dangerous card used by Zakira during Shobu Kirifuda's time hidden in the deep underground of the park.

Duel Masters Versus Revolution
He made his first appearance as a hologram after Lulu Takigawa refused to sell her card shop and made his appearance again together with his elite duelists; Basara, Hakase and Rambo.

At one point of time, Basara defied his orders of not to duel Lucifer and arrived to the scene by using one of the robots as a communicator. After Basara lost to Lucifer, he destroys Basara's motorbike. He then instructed Duemouse to guide Basara to the deep undergrounds. Upon Basara obtaining Forbidden and being able to suppress its dark power, he made a sarcastic remark to be careful.

When the workers in the underground city went on strike (in which the cause is Rambo's actions of blasting a tree in episode 20), he launched himself out of the white castle to get more electricity. Lulu, Katta Kirifuda and Bucyake chases after him all the way to the school grounds where Hokaben and his baseball team are having overnight training for the match finals. Hokaben bombarded the President with baseball hits before settling with a duel. He easily won and took away all of the power meant to light up to training grounds.

At one time, he kidnaps Kojiro Sasaki's brothers to make Kojiro defeat Katta and eliminate him from the competition. However, his plan was foiled by Kojiro when he gave Katta one point.

Deck
He uses an all civilization deck reminiscent of Five Color Faerie Miracle with many Hall of Fame cards. His main trump card is Unidentified which he uses to spam multiple strong finishers.

Trivia

 * It might be possible that he has relations with Zakira in the past as he kept his card Forbidden. To add it up, he specifically targets Katta Kirifuda, who was the younger brother of Shobu Kirifuda, which correlates to Zakira being an enemy of Shobu.
