Dragon

Dragons are large mystical creatures which resemble winged reptiles. Some if not all possess the ability to breathe fire.

History
Dragons apparently reside in other dimensions. When the hell goddess Glory used the Key to break down the barriers between dimensions, a dragon flew through one of the cracks in reality into Sunnydale. The barriers were eventually restored upon Buffy Summers' death, although the fate of the dragon is unknown.

When Angel brought down the Circle of the Black Thorn, the Senior Partners retaliated by unleashing an apocalyptic horde of demons upon Los Angeles, including a dragon. Angel expressed a desire to slay the dragon, but upon discovering that it was actually benevolent, they pair became allies.
