Out of gratitude for being freed from the legendary Z Sword, Old Kai explained that he would release all of Gohan's dormant power. After 25 hours straight of the Old Kai walking around Gohan performing a sacred ritual and then sitting in front of him to unlock his potential, Gohan finally tested out his new power by powering up like for the Super Saiyan transformation at Old Kai's suggestion. Doing so, only Gohan's eyes change to take on a sharper shape while he otherwise remains normal. Old Kai explains that Gohan's new normal levels of power have become so high that he didn't need to transform. A short time later, Gohan is transported to Earth for a rematch with Majin Buu (wearing his father's signature gi, courtesy of Kibito's Magic Materialization) who had now transformed into Super Buu. Then, evil copy of Mystic Gohan is seen Inside Buu.
- While Gohan's potential was unlocked by the Old Kai, a lack of training will affect the effects of the ritual, as seen in the Dragon Ball Z: Resurrection ‘F’ movie and the anime arc of Dragon Ball Super adapted from the movie. While Gohan kept a large amount of the extra power, he required his Super Saiyan state to tap into his true potential and even he could only keep it up for a short while.
- Evil copy of Gohan Inside Buu, has more brown skin instead.
- In Dragon Ball Z: Shin Budokai and Shin Budokai - Another Road, Gohan has Dark Brown skin in this state.
