Swamp Dragons are a species of pseudo-Dragons as they are not descended from actual Dragons and therefore originate in the Human World and not the Dragon World. They are bulky, with tiny wings, a large mouth, and hairy backs. They are allied with the Vorgan, although a few have been tamed by other factions (a few Iron Raiders sets contained Swamp Dragons and a few Swamp Dragons are seen pulling Odaku siege weapons in the Metal Ages film).

Fernbogg is actually a Plasma Dragon, however he is known as the "Swamp Dragon" and is therefore included here.
