Ununnilium: •SG-1 had more then those. The Re'tu, the Re'ol, the Tok'ra and one could even argue to include the Free Jaffa to the list.

SG 1 emphasized the disposablilty of the Muggle Planets by always calling them by their gate number P 3 X 254, NEVER by the nae of the people who live there. At least if they had Play The White Man and named the planets "Carterland", "Danielopolis" or "Tealc'hborough", it would have meant they CARED about those places.

"Avatar The Last Airbender had Fire Nation playing the Big Bad and The Water Tribe and The Air Nomads both more or less affixed to their own hats, the Earth Kingdom had to act as a convenient catch-all for miscellaneous fantasy / adventure archetypes, Red Shirt, Mauve Shirt, or otherwise."

I think this trope is starting to melt. All of the nations in Avatar had an entire season on them (except for Air, which is where the main character comes from). In other words, not unimportant.

[[Main/Characters Percy Jackson and the Olympians Would it be alright if the Aphrodite and Hephaestus cabins qualify as justifiable examples of the Hufflepuff House trope, considering that not much was said about the latter and the former did not have many fight-worthy cabin members shown, before the latest cabin-head as of the end of The Lost Hero?]]

Blast it, i can't seem to get the link right!
