Nobody ever says the word "Indian", but the guy who says, "Manhattan belongs to *my* people," sure looks Amerind to me. Given the theft of the entire continent of North America and the genocide of its native peoples, is Superman (an uninvited immigrant himself) really fighting on the side of justice this time? Fascinating food for thought, but a Superman cartoon is not about to spend too much time exploring these notions. At any rate this is *still* better than any of the features

The "fanatical extortionist" is definitely Native American. Just that M.O. gives the villain more subtext than any of the other villains in this series, although it's still racist to a degree.
