Watch DragonBall Kai episode 92 (The Tears that Disappeared into the Sky! The Angry Super Awakening of Gohan) here! I have also included DragonBall Z episode 184 (US version dubbed and JP version subbed) to compare the scene of Gohan ascending to Super Saiyan 2.
Dragon Ball Legends webmaster. Crono created DB Legends back in 2007 to focus on news of the anime and at the time the live action Dragon Ball movie, Dragonball Evolution.
