Janemba

How Janemba joined the Tourney
Janemba is incarnated in the Other World into the Saike Demon, a teenage ogre responsible for watching the Soul Cleansing Machine, when the latter slacks off and causes the cleanser to explode. The evil formed around the ogre mutates him into a giant, yellow, and childlike being who begins to turn Hell into his own paradise.

Goku and Pikkon are interrupted from their match in the Other World Tournament to fight Janemba, Pikkon being left behind to free King Yemma from the barrier that Janemba created around the Check-In Station.

Eventually, Janemba's weaker first form is destroyed by Super Saiyan 3 Goku, forcing a transformation into his second state, which enables him to overcome Goku. Vegeta appears and assists Goku, but neither of them is strong enough to defeat Super Janemba. The two eventually defeat Super Janemba by fusing into Gogeta, who destroys Super Janemba by purifying his pure evil energy and turning him back into the Saike Demon.

A month had passed since the crisis in Hell. The Special Forces Outer World Investigation Agency watched over the essence of Janemba that was regrowing. Soon, he burst free and killed the soldiers in the room. He spared Major Jax Briggs, only so he can destroy him in the second Tourney.
