Well since everyone here wants to pick XI's Dragoon as "the" Dragoon (since they're too closed-minded to open up to other avenues of possibilities) from here on out, I will only hope for the original incarnation of Dragoon.

Dragoon's first appearance in FF: As Dragonriders.
Traditional definition of "Dragoon": Mounted calvary.

Well darnit, if we don't get to fight while riding a Dragon/Horse mount this just ain't gonna be a Dragoon. /armfold. /pout.
