Sokka

Sokka is a boomerang man. This is basic knowledge, but some people force me to put it on wiki pages, Jennifer Laurentine Waybright. Yeah, that's right, you know who you are.

History
Sokka started out by creating his war fursona and trying to fight the Fascist Fire Oofers (trademark pending). Then, WaterFeminist and Aang took him to the north pole to stand around as they learned to make liquid disobey the laws of physics (who still follows those things amirite?). Along the way, he met a Succhini, who force fed him Respect Women Manuals, and he became addicted to it.

From there on out, he performed acts of egregious s o k k. He fell in love with the moon, taught a politician critical thinking skills (something that most real world politicians can only dream of), refined his war fursona in an invasion of the fire nation, defeated a cyborg pyrotechnist with his boomerang, forged a sword from one of his lunar ex's kidney stones, and ruined a fire nation engineer's birthday by blowing up all their fancy ships.

Stupid fancy ships, with their "Flight" and "Weapons technology". Happy now, Jennifer?

He then became a wolf and told everyone he died so he could spend the rest of time trying to get You to come down from the moon COME DOWN FROM THERE YUE YOU MIGHT FALL, CHILD
