Video Games

• Sumo Slammer Space Wars: A game not due to be out until Christmas. In "Perfect Day" two boxes full of them fell off of a truck driving by. It is unknown if they were a real game within the series or just a ploy created by the Forever Knights, but because the dream world was created from Ben's memories it is most likely real.
• Sumo Slammer Smackdown: A video game that features Ishiyama and Kenko. The episode "Game Over" primarily takes place within this game.

Other Merchandise

• Sumo Slammer Cards: Cards for the franchise Sumo Slammers. Their are five in a complete set; two blue cards, two red cards, and one super rare gold cards. Ben has been looking for a gold card everywhere. By Alien Force he has found one but he doesn't really care about it as much as when he was 10 meaning it was just a fad that he grew out of. He keeps the card in the box he kept the Omnitrix in for 5 years.
