Pluto is a skilled robot who was in Astro Boy and Pluto. In Astro Boy, he appeared in one episode and lost before one hit. In Pluto, however, he got a super form and utterly destroyed Astro Boy. He also beat Gesepi, Gamma, and 5 others; no one could stop him. Sailor Pluto has the power of time. With that power she should almost be unbeatable, but like all people who wield the power of time, she doesn’t use it right. To make up for this, she has beams and a sceptor, while Pluto has missilles. Pluto wins.
