Season 1

A proud warrior of the FM Planet, Omega-Xis, betrays his kind and escapes to Earth where he makes contact with Geo Stelar. Like his fellow extraterrestrials called FM-ians, Omega-Xis is capable of initiating a process known as "Electromagnetic Wave Change," which transforms ordinary humans of the same frequency as themselves into "EM Wave Humans," allowing them to freely operate in the EM Wave World. With these new powers, Geo becomes known as Mega Man, a hero of Echo Ridge.
