Ultimate Swampfire is the evolved form of Swampfire.


Ultimate Swampfire has the appearance of a humanoid tree instead of a walking plant like Swampfire. Ultimate Swampfire's body is dark brown in color, and now has three blue gooey shells containing an organic, blue colored gel-like solution of napalm on his arms and a large one on his back, that he uses to generate blue colored flames that are about three times hotter than Swampfire's. He also has a smaller pod on his front, through which his face can be seen. Ultimate Swampfire's body is composed of petrified wood.

Ultimate Swampfire wears the evolved Ultimatrix symbol on his chest.
