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 face, 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. Ultimate Swampfire's body is composed of petrified wood.

Ultimate Swampfire wears the evolved Ultimatrix symbol on his chest.
