Ken is the main character of Chargeman Ken! His powers allow him to transform into the superhero Chargeman Ken. However, his powers rely on there being at least one source of light nearby. Ken fights against the Jurals with his light-powered pistol, and his ship, Skyrod.

It is the year 2074. In a world threatened by aliens... an unlikely hero emerges! Ken Izumi may look like an ordinary 10-year-old boy, but he secretly possesses weapons, armor, and accessories that transform him into the superheroic Chargeman Ken. Ken protects his mom, dad, little sister Caron, robot pal Barican, and the rest of mankind from the diabolical Juralians, shape-shifting alien invaders bent on terrorizing the earth with flesh-eating butterflies, booby-trapped scientists, an evil doll, a prison break, alien mummies, a kid that sets stuff on fire, a song that makes you die... basically, they have about 65 plans for world domination.
 
The only thing standing between the fragile human race and conquest by the Juralians is Chargeman Ken and his unquenchable thirst for fiery, atomic justice!
 
Chargeman Ken originally ran on Japanese broadcast television in 1974. This delightfully bizarre kids’ cartoon was rediscovered in 2007 by Japanese fans, who flocked to Chargeman Ken for its strange artwork, clumsy animation, and fantastically inept stories... some of which have been banned from Japanese TV altogether.
