The Bone Dragon is a Support Unit in Kingdom Under Fire:The Crusaders. It is unique in that, while it has requirements as a unit (Which is 9 Melee, 9 Ranged, and 9 Curse), it cannot be used by normal means. It shares this trait with the Battaloon. You do however, gain control of this during Regnier's second-to-last mission and last mission. When it attacks, it uses large fireballs, and is the only thing strong enough to peirce Encablossa. It can attack both ground and aerial units.
