Cell is once again in his perfect form after regenerating from his own explosion. He reveals that one single cell was left after the explosion, and that was enough for him to come back. Vegeta becomes enraged at the loss of his son and attempts to take on Cell on his own. He unleashes a barrage of blasts at Cell, but is eventually tossed aside easily by the even more powerful Cell. Cell aims a blast at Vegeta, attempting to finish him off, but Gohan dives in front of him and takes the blast himself. Gohan survives, but is severely injured, losing the use of his left arm, and what's more, Krillin has no senzu beans left. Cell then begins to charge up a Kamehameha blast to destroy the Earth, and proclaims that he will live forever.
