Ultimate Swampfire is the Ultimatrix's DNA sample of an Evolved Methanosian.


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.

Powers and Abilities

  • Pyrokinesis
  • Fire Bombs
  • Seed Generation
  • Underwater Propulsion
  • Pyrokinetic Flight

Ultimate Swampfire is more resistant to damage than Swampfire.

Ultimate Swampfire has lethal fire bombs on his arms which he can throw as weapons.

Like Swampfire, Ultimate Swampfire can also ignite methane in his hands using his napalm, except that the fire he can produce as a result is blue. As mentioned above, his flames are three times more powerful than Swampfire's, as they can melt through a brick wall.[1] He can also produce a larger and stronger blast of fire when he puts his hands together.

Ultimate Swampfire can shoot blue methane projectiles from his hands that can multiply into small blue gas bombs that explode on impact.[2]

Ultimate Swampfire can propel himself underwater and in the air.

Ultimate Swampfire has the same plant abilities as Swampfire.

Ultimate Swampfire seems to be a lot faster than he looks, as seen when he snuck up behind Eon so fast that Eon didn't notice him.[3]


Ultimate Swampfire is shown to be vulnerable to electricity.[1][4]

Unlike Swampfire, Ultimate Swampfire cannot regenerate. However, Matt Wayne thinks otherwise.[MW 1]


  • Ultimate Swampfire first appeared in The Final Battle: Part 2, where he battled Vilgax. During the battle, water poured into the ship as it went underwater and Vilgax turned into his true form. Vilgax then tried to eat Ultimate Swampfire, who turned into Jetray and retreated.
