Swampfire

Swampfire is the Omnitrix'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-patterned 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 stench 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 first design simialr to his Alien Froce/Ultimate apearance except for he has five fingers on his hands. Swampfire's skin is now olive green and his arms are larger. He now has a visible chin. The red petals on his shoulder along with the green thorns on his body are thinner and longer. His torso design has changed, splitting the black parts on his waist into two. The Omnitrix symbol has also moved from his chest to his stomach.

As of Charmed, I'm Sure, Swampfire's second appearance is plant-like, but with major changes. His skin color is now light green. His hands are now colored black with yellow claws. He has ten horns, three on both arms, one on both feet, and one on his forehead. He has a parts of a robe around his neck. He also has red spots on his elbows and knees. the Omnitrix is still on his stomach.

Powers and Abilities
Swampfire has the ability to ignite methane in his palms to project fire.

Swampfire's methane can make the Incurseans unconsiuous. As displayed by Negative Swampfire in The Final Battle: Part 1, his methane is strong enough to knock a human unconscious.

In Ben 10: Alien Force (Video Game), Swampfire was revealed to emit a methane which causes plants to grow over enemies, channel his flames into a concentrated fireball, tunnel underground, and burst in a coating of flames. He could launch a concentrated, straight beam of fire.

Swampfire is also enabled to have limited flight abilities by launching fire from his palms as jet propulsion, as shown in War of the Worlds: Part 1.

In Vilgax Attacks, Swampfire was capable of launching a flamethrower-like blast, as well as igniting his hands for "flaming fists", creating a ring of fire to roast enemies, and causing thorny vines to sprout from the ground.

Swampfire has a high degree of chlorokinesis. Swampfire is able to manipulate his biological agriculture to stretch his limbs for multiple purposes, as demonstrated in Vengeance of Vilgax: Part 2 and Ghost Town. He can also reattach detached body parts by manipulating his vine-like "veins" to reach out and meld with the insides of the detached limb. Due to his plant-like composition, he is also capable of regenerating at a quick pace.

Swampfire has superhuman strength, being able to push over a Highbreed weather tower as well as hold his own against Vilgax with his bare fists.

Swampfire has a form of enhanced speed, as when he was displayed running towards Vilgax in The Final Battle: Part 2, the scenery was blurry as he was speeding past.

In X = Ben + 2, Swampfire was able to walk straight through an iron bar in his holding cell.

Weaknesses
In Vengeance of Vilgax: Part 2, Swampfire was cut up by Goop's Anti-Gravity Projector continuously, preventing him from regenerating.

Swampfire can be frozen, though he can thaw out by igniting the methane in the palms of his hands.

According to himself, Swampfire cannot control weeds.

Swampfire's swampy stench makes it hard to hide from anybody with a nose.
