Ep. 81: Ultimum impetum Vegetae! Cellum invictum vince!

81

Desperate to kill Cell, Vegeta resorts to using his ultimate attack, the Final Flash. Vegeta calculates his attack and avoids destroying the entire Earth and also manages to take off Cell's right arm, but with Piccolo's genes Cell easily regenerates his arm. Cell knocks Vegeta unconscious and Trunks takes this chance to unleash his hidden powers onto Cell. Trunks momentarily lets Cell push him around a little in order to create a chance for Krillin to take the unconscious Vegeta to a safe location. Now that Vegeta is out of commission, Trunks and Cell can begin their real fight. (Source: Wikipedia)
