Eggman has a lot of good inventions and I’m particularly fond of his Egg Emperor form. That being said, Astro Boy’s physical strength is said to surpass even that of Mega Man’s and his arm cannon can easily blow up most adversaries. Eggman won’t be able to keep up with Astro Boy’s superior speed and one punch would shatter just about any one of Eggman’s robots. Astro Boy is one of the original fighters and he’s not going down anytime soon! Astro Boy wins.
