Swampfire

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

Appearance
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.

In Omniverse, Swampfire's design hasn't changed at all except for a different shaped head and the Omnitrix symbol moving from his chest to his stomach. He also has more root-like feet and has five fingers.

Powers and Abilities
Swampfire has the power to project fire though his palms and control plant life.

Swampfire can reattach detached body parts or regenerate them.

In Ben 10 Alien Force: The Video Game, Swampfire can dig underground and pop up in a burst of fire, shoot a straight beam of fire, shoot gas to make plants grow over enemies, and focus his flames into a powerful, concentrated ball of fire.

In Vilgax Attacks, Swampfire can makes vine spikes come out of the ground, shoot a flamethrower-like beam of fire, wield flaming fists, and burn enemies with a ring of fire.

In Cosmic Destruction, Swampfire can grow plants through the ground and make a ring of fire on them.

Shown by Negative Swampfire in The Final Battle: Part 1, Swampfire can spray sleeping gas.

Swampfire has proved to be very strong, able to push a Highbreed weather tower over and hold his own against Vilgax with his bare fists.

In War of the Worlds: Part 1, Swampfire was able to fly by shooting the fire from his hands and pointing them at the ground.

In Vengeance of Vilgax: Part 2, Swampfire can stretch his body parts similar to Wildvine, shown when he stretched his arms to grab Goop and when he stretched his fingers to dig a tunnel in Ghost Town.

In The Final Battle: Part 2, Swampfire has enhanced speed (the scene of him running towards Vilgax was very blurry as if he was moving at high speed).

Weaknesses
Swampfire can be frozen, he can thaw out by igniting the methane in his wrists.

According to himself, Swampfire cannot control weeds.

Swampfire's bad smell makes it hard to hide from anybody with a nose.
