Cell (Dragon Ball character)
However, Cell is able to survive thanks to his unique physiology, which allows him to regenerate from a special nucleus in his head and grow more powerful whenever he has almost been killed, returning to his Perfect form even stronger than before. He easily kills Trunks, and when Vegeta attacks him in retaliation, he easily swats him aside. Before he can kill him, Gohan takes the blast in his place, which breaks his arm. With victory in his grasp, Cell decides to destroy the planet with one last Kamehameha, claiming he has the power to destroy the entire Solar System. Assisted by his father in spirit, Gohan retaliates with his own Kamehameha, ultimately overpowering Cell with Vegeta's help, destroying his cell nucleus and killing him once and for all. Mr. Satan, however, takes credit for the victory and becomes a hero.
