Kip. 187: Cell's Mighty Breakdown
Gohan, no matter how many attacks Cell throws at him, is totally unfazed by Cell's attacks, and it looks more and more like Gohan will win the battle. Desperate, Cell aims a massive Kamehameha wave at the Earth, hoping to destroy it. Gohan counters this with an even bigger wave, which hits Cell, and dismembers him. Gohan starts to reveal the sadistic qualities of the Super Saiyan 2, preferring to let Cell suffer, despite Goku's protests that Gohan must destroy Cell now. Cell regenerates himself, and becomes enraged, and powers up to an extreme power level, but makes the same mistake that Trunks did, and is unable to hit Gohan due to his size. Gohan then delivers several crushing blows to Cell, including a kick to his gut, which eventually causes Cell to regurgitate Android 18. (Source: Wikipedia)
