Dragon Ball Kai

To Goku and Gohan's great concern, Tien repeatedly fires his Tri-Beam, drastically draining his ki in order to hold Cell down while Androids #16 and #18 escape. Tien eventually runs out of ki and collapses, at the mercy of a furious Cell. Unwillingly to wait idly at Kami's Lookout anymore, Goku uses his Instant Transmission to come to Tien's aid. While confronting Cell, Goku also notices that Piccolo is still alive, and teleports back to the Lookout with the two fallen warriors. Shortly afterward, Trunks and Vegeta emerge from the Hyperbolic Time Chamber, stating that they have successfully surpassed the level of Super Saiyan. They leave to confront Cell, while Goku and Gohan prepare to enter the time chamber for their own training. Meanwhile, Cell begins destroying islands in a bid to make #18 show herself.
