First Appearance Ben 10 Returns: Part 1

Swampfire is the Omnitrix'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-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 similar to his Alien Force/Ultimate apearance except for he has five fingers on his hands. Swampfire's skin is now olive green and his arms are larger.  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 or "blossomed"/"matured" form, is plant-like, but with major changes. He looks more muscular and taller. His skin color is now light green. His face is now colored yellow, red, and orange. His pupils are gone. His chin is more visible. His hands are now colored black with four yellow claws and a yellow hole to unleashed his fire powers. He has six red horns with yellow spots, two on each forearm, and one on each shoulder, along with a green horn on each foot, knee, and elbow. He now has a large collar raised up around his neck. The Omnitrix symbol is still on his stomach.

Powers and Abilities

  • Swampfire shooting fire
  • Swampfire growing plants from the ground
  • Swampfire reattaching his hand

Swampfire has the ability to ignite methane in his palms (from yellow hole in "blossemed" form) to project fire, like fire blast or flamethrower.

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.

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'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.

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

In Charmed, I'm Sure, Swampfire's "blossomed" form revealed that he has complete control over the Mutant Pumpkins from Anur Transyl. His fire blast looks more powerful. He can grow plants from the ground just by raising his hand.

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. In his "blossomed" form, he appearances to be even stronger and more durable than before.

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.


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, though after 'blossoming,' he gains the ability to command the hordes of Mutant Pumpkins

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

In Ben's case, his Omnitrix is unable to select a different alien and he develops large facial pustules in his human form, until his Swampfire form has fully blossomed.
