As I noted before, the show is almost devoid of real Inca culture or history. Here are the only references I've seen:
These references to gods are instructive, so let's look at them. According to Wikipedia:
In this episode, Kuzco and his friends are guarding a valuable mask. Kuzco falls asleep and thinks (or dreams) he sees Viracocha, who has come to retrieve the mask.
Kuzco correctly identifies Viracocha as "the creator, the great power above." Does he bow down to this supreme deity? No, he's so egotistical that he expects Viracocha to bow to him. He then imagines Viracocha imitating a llama and doing a stand-up comedy routine.
Could there be a better example of how The Emperor's New School disdains Indian culture? A supreme deity is treated like a joke. To the show's creators, he's no different from Santa Claus or the Easter Bunny. He's infinitely less important, not more important, than a human emperor who should be groveling at his feet.
Imagine if The Emperor's New School had shown the Christian God or Jesus prancing on all fours like an ass. It's unthinkable. Yet the show has been just that insulting to an Inca god who's as powerful and real as the biblical God.
Later, Viracocha appears to appear in a doorway. The school's instructor blurts out, "You're supposed to be a myth!" (The figure turns out to be Pacha, who has borrowed the mask for a masquerade, not Viracocha.)
There you go. The Christian God is so holy that TV shows rarely mention him for fear of upsetting someone. Indian gods are myths to be made fun of.
The same could be said of Indian culture, or Indians. According to The Emperor's New School, they aren't real people, they're myths to be made fun of. They had some wacky adventures when they lived centuries ago in a magical never-never land, but now they're dead and gone.
In this episode, Kuzco goes to the Temple of the Sky God. This god is represented by a statue that looks like Virococha holding a lightning bolt like Zeus. Because people resent him, Kuzco wishes he'd never been emperor. In a blast of magical power, the god (or the statue) grants his wish.
Again we see a lack of respect for Indian culture and religion. There's no solemnity or spirituality in this Inca temple. The god is a Wizard of Oz-style magician who grants wishes to anyone, whether he's been faithful or not. This god is less discriminating than Santa Claus, who at least requires people to be nice.
According to The Emperor's New School, an Indian civilization like the Inca empire is just like every other fantasyland: Oz, Wonderland, Narnia, et al. If someone announced these people lived in a galaxy far, far away, few viewers would think twice about it. Indians might as well remain in Neverland with the pirates, mermaids, and fairies, because they're no more real than other imaginary creatures.
No wonder so many kids think Indians are dead and gone. That's the message they're getting from Saturday morning TV.
