History

Ben 10

In, Game Over, when Ben and Gwen were sucked into the Sumo Slammer Smackdown video game, he aided them in their progress. At first, he believed Ben was his arch enemy, Kenko the Shapeshifter, but was convinced otherwise by Gwen. He is very honorable, responding that "a sumo never cheats!" when Ben asked him if he knew any cheat codes to help them out, but decided to make an exception and show them a shortcut to Level 13. He considered Gwen a far greater fighter than Ben. He and Gwen fought Kenko while Ben searched for the Upgrade icon on Level 13. Kenko took his last life, but Ben revived him as Upgrade. Ishiyama declared that he found Max, who joined them at the last minute and was little more than a rookie, to be the greatest warrior of all for knowing that the cleansing Sumo salt would reveal Kenko's true form when he disguised himself to deceive Ben and Gwen.
