Ultimate Swampfire is the Ultimatrix's artificially evolved DNA sample of a 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 kerosene napalm on each of his arms and a large one on his back.[merch 1] 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[]

Ultimate Swampfire has a high degree of chlorokinesis, allowing him to telepathically interface with plant life, among other things. Additionally, Ultimate Swampfire has an increased degree of chlorokinesis compared to his devolved counterpart.[merch 1]

Ultimate Swampfire can ignite a kerosene gel-like solution in his arms to generate blue-colored flames.[merch 1] These flames are much hotter than Swampfire's, as they melted through a brick wall[1] and can disintegrate a Petrosapien's shard projectiles in midair, the latter of which was demonstrated by his sentient counterpart.[2][note 1] Ultimate Swampfire is also capable of limited flight through means of launching fire from his palms as jet propulsion.[3]

Ultimate Swampfire has fire bombs on his arms which he can pick off and throw as lethal explosives, one of these fire bombs was able to completely destroy the Plant Alien after being thrown inside of it.[4] He can also shoot out a large cluster of fire bombs from his hands that separate and detonate individually, providing a blast range over a wider area.[3]

Ultimate Swampfire retains Swampfire's ability to generate seeds and vines,[5] as well as his regeneration[CN 1][CN 2][MW 1] and elasticity.[3]

Ultimate Swampfire is very strong, as he was able to force the mouth of the Plant Alien open to throw a fire bomb inside.[4]

Ultimate Swampfire much more agile than he looks, as seen when he snuck up behind Eon so fast that he didn't notice.[5]

Ultimate Swampfire can breathe[merch 2] and generate fire underwater.[3] Ultimate Swampfire also resists radiation. However, Ultimate Swampfire has been shown to be hurt by the force of a radiation attack.[1]

Ultimate Swampfire is vulnerable to electricity, such as that generated by an Amperi.[1][6]

  • Ultimate Swampfire is the first Ultimate form to be used by Ben, which is a reference to Ben always turning into fire-based aliens first: Heatblast, Swampfire and Ultimate Swampfire.
    • He is also the only Ultimate form used by Ben to appear before Ultimate Alien.
  • Ultimate Swampfire is the only Ultimate form to be temporarily destroyed and removed from the Ultimatrix.
  • In a beta cover for an issue of the Cartoon Network Action Packs, Ultimate Swampfire was colored red with yellow napalm shells, resembling Heatblast.
  • Ultimate Swampfire was the Alien of the Month in October 2011.
  • Ultimate Swampfire was designed by Steven Choi.[SC 1]
  • Had Ultimate Swampfire appeared in Omniverse as one of Albedo's transformations, Derrick J. Wyatt would have probably redesigned him to look a little creepier, "like when Ichabod Crane rides through that haunted forest".[DJW 1]
  • If Ben 23 were to have an Ultimatrix and use its Evolution Feature on Mr. Mucky, the resulting transformation would be called "Monsterizered Mr. Mucky".[DJW 2]
  • Ultimate Swampfire was Derrick's favorite Ultimate form because he liked how he looked the most, considering him to be a million times better than regular Swampfire.[DJW 3][DJW 4][DJW 5]


  1. Despite methane possessing a higher calorific value than kerosene in the real world, meaning it burns hotter and provides more heat, Ultimate Swampfire's flames are depicted as significantly more powerful than his unevolved counterpart's in the show.
