Well... It was during the Cell Games, Goku sacrificed himself, teleporting Cell to King Kai's planet, but dying in the process, only thing, Cell not only came back, but stronger. Later, Hercule fought Cell on his own, but what were you expecting? Of course he lost. Then Gohan fought Cell but also got his ass handed to him. Now, it was your turn.

Cell: "Come face me, weakling."
