Goku saves Tenshinhan and Piccolo, and takes them to Kami's Lookout. Trunks and Vegeta emerge from the Room of Spirit and Time. Vegeta (in Super Saiyan 2nd Grade or "Super Vegeta") beats Cell, but Cell makes him believe he must absorb #18 to become stronger. Vegeta lets him do it. Cell absorbs #18 and reaches his Perfect Form. Vegeta, Trunks (in Super Saiyan 3rd Grade) attack him but are defeated. Trunks was stronger but slower.
