Swampfire is the Omnitrix's DNA sample of a Methanosian from Methanos.


Swampfire is a humanoid plant like alien. His body is mostly green. Swampfire has a black face with a red and yellow flame pattern around it. His shoulders have petals and his feet are root like. On his sides there are black. He has a rotten scent that worsens with heat. The Omnitrix is on his chest (in Omniverse, the Omnitrix is on his lower torso). In Charmed, I'm Sure, his appearance changed twice before he matured.

Powers and Abilities

  • Swampfire can shoot fire by igniting the methane gas inside his body.
  • He can control plant life.
  • Swampfire can regenerate himself and reattach lost limbs.
  • He can spray several types of gases.
  • Has enhanced strength.
  • He can fly by shooting fire at the ground.
  • Enhanced speed.
  • Swampfire can stretch his body parts
  • He can shoot seeds that quickly grow into huge vines 
  • He can grow vines from his hands and use them as whips


Swampfire can be frozen but can easily thaw himself out. He can't control weeds. Swampfire's smell makes it hard to hide from anyone with a nose.
