Spitfires are a desert breed of dragon. Their dull brown bodies contrast with their brilliant turquoise markings, and they only blaze brighter when these dragons fight. Spitfires are notorious for their territorial natures, and the wing-edges of most are ripped and tattered before their first year is out. Spitfires are also noteworthy for their brilliant blue fire, which is used not for hunting or fighting, but rather for making glass caves from the sand, in which the dragons can soak up the sun.

Dragons are highly-intelligent reptilian creatures that—from a human perspective, at least—appear to live forever. Many different varieties of dragon exist, each with their own unique qualities, habitats, and behavior. Adolescence in dragons is usually marked by the growth of a hatchling’s wings, although not all breeds of dragons grow wings and some breeds have other traits that indicate the beginning of maturation. In Galsreim, dragons and humans coexist peacefully.

Seifer is extremely aggressive and competitive; he refuses to be anything less than the best at whatever he does, creating an intense rivalry between himself and Squall, who chose a similar path to Seifer's. This desire to be the best occasionally comes into conflict with his desire to protect those who can't protect themselves. Most people just don't realize this, as he hides it behind his snarky, rude, and borderline violent bad attitude.

He has a poorly hidden soft spot for Zell, which he shows by picking on her relentlessly. He knows all of her buttons, and never hesitates to press each and every one of them. He has mellowed out now that he's in a relationship with her, though.
