Sho du Baym

Sho du Baym is the main antagonist in Yu-Gi-Oh! Dupower. He is determined to get Dupower Dragon and Dupower Phoenix from Venabu and Mecedu Zooka, as well as their Century Items. He is also one of their teachers at Bluewood Middle School.

Appearance
Sho is a very tall, skinny man who wears black pants and a black vest covering up a white dress shirt. He wears a long, light green tie. He has neat, black hair, and has pointed ears. The base of his Duel Disk is completely black, and he places his Deck in the middle, with a thin LP counter on the side, and a slot for the Graveyard on the other side. Sticking out from his Duel Disk is a black structure shaped like a tiger slash, with two thin, red streaks stretching down the middle with 6 squares each for his card zones and his Extra Deck.

Guam Koa
Apart from Venabu and Mecedu, Guam is Sho's least favorite student, and is constantly looking for ways to get him in trouble. In the first episode, Sho gets mad at Guam and sends him to the hallway.

Venabu and Mecedu Zooka
Sho hates Venabu and Mecedu and will do anything to get their Dupower monsters. He would expel them if he could, but for one thing, he doesn't have the authority, and also, he needs to keep them close so he can complete his goal. Their first Duel was in Dupower, where the twins won, but Sho challenged them to a rematch quickly afterwards.
