If you're a faithful "Dragon Ball Z" viewer, then you probably remember the Grand Kai. Besides being the "boss" of the cardinal Kais (North, South, East, and West) and the Kai with the most facial hair, the Grand Kai is memorable for his laid back, almost hippie-like demeanor. His biggest role in the anime is holding the Other World tournament, where he promises Goku and Pikkon a training lesson for being the competition's finalists.
While the Grand Kai's also appeared in the "Dragon Ball Z" movies, "Dragon Ball GT," and even "Dragon Ball Z Kai: The Final Chapters," he doesn't show up in the original manga at all. One might easily think that, like North Kai's grasshopper Gregory, the Grand Kai is an anime-only character. Leave it to Piccolo, then, to confirm the character does exist in the manga version of the Dragon Ball universe. The reveal happens after Piccolo forfeits his match with the mysterious Shin, who he believes to be the Grand Kai. Shin quickly corrects him, however, explaining he's actually the Supreme Kai, instead. That scene, which the anime adapts pretty faithfully, proves that the Grand Kai exists somewhere in the source material. Perhaps one day, the "Dragon Ball Super" manga will finally deal the Grand Kai in.
