First and foremost I would like to point out that Redino got away with freaking Red X, so this shouldn’t really be a problem. Anyway, here's my Ranger charry.
Sokka sports a genius level IQ matched only by his love of sarcasm. His ingenuity and natural skill with Pokemon lead him to pursue a position as a Ranger, and in spite of his tendency towards laziness he is a fairly good one. Sokka also has an interest in science and technology, and thus enjoys excursions into the Abandoned Power Plant area the most, although he will willingly take people elsewhere. He also has no understanding of the concept of subtlety. Intricacy, yes, but not subtlety.
Other: He has a habit of throwing his boomerang as he walks to keep his fingers busy.
