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 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.
