チャージマン研! (1974)

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. 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!
