Swampfire is the Codon Stream's DNA sample of a Methanosian from the planet Methanos.


Swampfire is a humanoid plant like alien that has an overall green and black colored body mostly with a flame-pattered head and root-like feet seemingly holding rocks. Also, his shoulders and head have red petals. Swampfire is taller than an average human and has a distinct rotten smell that worsens with heat. His voice is very stuffy and nasally because he has no nose. Swampfire wears the Omnitrix/Ultimatrix symbol on his chest.

Powers and AbilitiesEdit

Swampfire has the power to control fire and plants. He can reattach detached body parts or regenerate them. His fire abilities include throwing fireballs, shooting flamethrowers, breathing fire, releasing heated air, and immunity to fire.

In Ben 10 Alien Force: The Video Game, Swampfire can focus his flames into a powerful, concentrated ball of fire. In Vilgax Attacks he can burn enemies with a ring of fire. And in Cosmic Destruction, he can grow plants on the gound and make a ring of fire on plants. (Overgrowth)

Swampfire's plant controlling powers include controlling other plants, spraying methane, vine generation, burrowing underground, and seed bombs that once thrown, grow into a flurry of vines and plants who are under his control. Shown by Negative Swampfire in The Final Battle: Part 1, he can spray sleeping powder.

Swampfire has proved to be very strong, able to push a Highbreed weather tower over and hold his own against Vilgax with his bare hands. In Ghost Town, it is revealed that he can stretch some of his body parts similar to Wildvine.


Swampfire is vulnerable to ice, he can be frozen. This is shown when Negative Big Chill was able to freeze Swampfire. However, this attack created little distraction as Swampfire broke free using a similar method that he used during the first Highbreed invasion, igniting the methane in his wrists and broke free when Negative Big Chill least expected it. According to himself, he cannot control weeds. Swampfire's smell makes it hard to hide from anybody with a nose.
