Andro Melos is one of the four original Andro Super Warriors who appeared in the manga of the same name as well as the miniseries, Andro Melos. This name is the alias of those who wear the Cosmo Tector. Benoit is the current user, with the role previously being held by his deceased father Cesar, followed by Zoffy.

While patrolling in space, a soldier of the Andro People named Cesar saw Zoffy being thrown into a black hole by Ace Killer and rescued him by giving Zoffy his Cosmo Tector, dying in the black hole in his place. Zoffy took on the alias of Andro Melos and saved the galaxy from countless catastrophes. He is later joined by Andro Mars in his battle against the monsters. After Ultraseven is seemingly killed and Andro Wolf appears to Andro Melos, Mars begins to think that Wolf is Ultraseven. They are proven wrong when they find Ultraseven being held by the evil Juda (the main antagonist of the show). After destroying Juda, it is revealed that he was a robot, Zoffy reveals who he really is and how he survived the black hole. Zoffy hands down his Cosmo Tector to Cesar's son, Benoit, and returns to the Land of Light with Seven, leaving the position of Andro Melos to Benoit.
