Sulu is a supporting character in Captain Underpants. He is a hamster that is adopted by George Beard and Harold Hutchins. He used to be Melvin Sneedly's pet, prior to George and Harold's adoption. He was also known as Sulu the Bionic Hamster, after Melvin combined Sulu with a bionic robot, transforming Sulu into a cybotic hamster using the Combine-o-Tron 2000.
Sulu appears in All Star Smashers as a Primary Spirit, as an Ace class, where you must fight Garfield at Plastination as a character of your choosing to obtain him. When fighting Garfield, his physical attack power will increase, hostile Assist Trophies will appear, and his general stats severely increase.
- Completing Sulu's Spirit Battle will also obtain Ben & Small.
