Get Angry, Gohan!
Get Angry, Gohan! Release Your Hidden Power! (「怒れ悟飯！眠れる力を解き」, Ikare Gohan! Nemureru Chikara o Hodoki; lit. "Get Angry Gohan! Release Your Dormant Power") is the ninety-first episode of Dragon Ball Z Kai. Its Japanese air date was January 30, 2011. Its American air date was November 25, 2011.
Super Saiyan Gohan shows no willingness to fight, and tries to convince Cell to end the Cell Games by explaining that if his hidden powers are brought to the surface, he will lose control and kill Cell. Opposite to Gohan's intentions, this actually intrigues Cell, who decides to deliberately enrage Gohan by inflicting enough pain to force him to unleash his true strength. After watching Gohan take Cell's punishment, Android 16 intervenes. Taking advantage of the fact that he emits no detectable ki, 16 grabs Cell from behind and declares that he is going to trigger his self-destruct bomb.
