Invincible Steel Man Daitarn 3

Souzou Haran was a brilliant scientist conducting research on Mars when he created a self-aware cyborg species called the Meganoids. The experiment went horribly wrong-the Meganoids rebelled, killing Dr. Haran and nearly his entire family. Only his youngest son, 16-year-old Banjou Haran, survived. Escaping Mars aboard a rocket with a solar-powered super robot named Daitarn 3-constructed from the planet’s unique metals-Banjou eventually settled on Earth. Now 18, he lives in a lavish mansion and battles the rogue Meganoids with the help of his loyal butler Garrison and his two companions, Reika and Beauty. Their mission is to stop the Meganoids’ sinister plan to forcibly "upgrade" humanity by turning everyone into cyborgs.
