The Fire Dragon is the third and final form of the Dragon Egg, the Super Unit of the ∑∫ỹriȱŋ. It evolves from the Baby Dragon after 3 turns.

The Fire Dragon has only 20 health, while other tribes' Super Units have 40 (or 30 for the Gaami and 20 & 10 for the Centipede), but it is devastating from a distance. Its splash skill hits all adjacent enemies to the target with reduced damage, making it invaluable when clearing grouped enemies, and the ability to travel over land and water indiscriminately is extremely useful.

It is possible to convert the Fire Dragon with a Mind Bender, with it then changing colour to that of the tribe which converted it.
