Robio is a minor character who appears in El Tigre: The Adventures of Manny Rivera. He
Not much is known about him, except that he is the son of Giant Robot Sanchez. But unlike him, he's not a villian, possibly because he's still a kid. He also cares very deeply about his father, as seen in "Mech Daddy", he was upset because he didn't respond to both him and Andra (Due to a caterstophic system failure), forcing Manny and Frida to control Giant Robot Sanchez for the rest of the episode.
Robio is a small robot kid with a hat, overalls, and hazel eyes.
