He's an ancient American robot (or something) who shoots lasers out of his eyes. Asking questions starts you down a path to someplace you don't want to be...
Sort of like Silver Streak, you could ask why his costume's red and the streak behind him is similar, but then you'll end up thinking about his origin. And from there, it's just a few inevitable steps to worrying about Forces Man Was Not Meant to Know.
(All things considered, though, the way they call out the South America part, I have to assume it's because he's more or less Caucasian.)
