When Uran tries to stop Atom and Pluto from fighting, she is attacked and injured. Atom, holding Uran in his arms, is completely defenseless. However, Pluto leaves Atom without attacking him. The feelings that had begun to grow in Pluto made him hesitate to attack. Still, Pluto had to complete his mission, so he continues to fight. Tenma kidnaps Dr. Ochanomizu to attract the attention of Atom, who tries to avoid the fight. At Brocken Volcano, and the battle of the century between Atom and Pluto finally begins. Pluto is supposed to be the stronger of the two, but he can't seem to settle the score, as the emotions in his heart are weakening his power.
