Swampfire

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

Ben as Swampfire
Swampfire is a humanoid, plant-like alien that has an overall green and black colored body, mostly with a red flame-patterned head and root-like feet, seemingly holding black rocks. His eyes are oval-shaped with points at each end with pupils copying the shape but are smaller. Also, his shoulders and head have red petals and his elbows and legs have green frills sticking out. Swampfire is taller than an average human and has a distinct rotten stench that worsens with heat. Swampfire wears the Omnitrix/Ultimatrix symbol on his chest.

In Omniverse, Swampfire's first design was similar to his Alien Force/Ultimate Alien appearance, except for having five fingers on his hands. Swampfire's skin was olive green, and his arms were larger. The red petals on his shoulders, along with the green thorns on his body, were thinner and longer. His torso design changed, splitting the black parts on his waist into two. The Omnitrix symbol also moved from his chest to his stomach.

Swampfire's first stage of "blossoming" was more muscular than his earlier design. He also lost his pupils, one of his red petals on each shoulder, and a green frill from each leg. The lines on his neck thinned and the lines on his chest moved upward and into a pointed down angle. His green color was also a shade lighter than his olive green.

Swampfire's second stage of "blossoming" has more muscle with the black lines being removed from his chest entirely. His red petals formed into a red thorn shape, with two being on each arm. The necklines were triangular and his shade of green was lime green. His face resembled his fully matured form except that instead of orange surrounding the eyes, there was black surrounding them.

As of Charmed, I'm Sure, Swampfire's second appearance, or his "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 and his chin is more visible. His hands are now colored black, with four yellow claws (with spikes on the knuckles), and yellow holes in the palms, used to unleash his fire powers. He has six red horns with yellow spots (aesthetically resembling flames); two on each forearm, and one on each shoulder, as well as a green horn on each foot, knee, and elbow. He now has a large collar raised up around his neck, which is yellow on the inside. The Omnitrix symbol is still on his stomach.

Albedo as Negative Swampfire
Negative Swampfire looks exactly like Swampfire in Alien Force and Ultimate Alien, except he has red eyes and his Ultimatrix symbol is red as well.

Powers and Abilities
Swampfire has the ability to ignite methane in his palms similar to a flamethrower. After his blossoming, he ignites methane from yellow holes in his palms. His fire blast is precise enough for him to shoot it at a cage with Kevin and Gwen in it, while the cage melted and Kevin and Gwen were left unharmed. His fire blasts are capable of harming Vaxasaurians.

Swampfire is also capable of limited flight through means of launching fire from his palms as jet propulsion, much like Heatblast.

Swampfire has a high degree of chlorokinesis. He can use seeds and gases projected from his body as weapons, as well as telepathically interfacing with plant life, to manipulate and instantly create biological agriculture. Plantlife exposed to Swampfire's gases will elongate, enlarge and ensnare enemies, seemingly being mutated by the gases. Some plants have a brief green aura when he influences them. His telepathic influence over plants even allowed him to free Max from the Highbreed Tree Monster, which used Max as a brain.

Swampfire can generate seeds from his body that phase into or pierce into any ground or flooring before turning to vine tentacles strong enough to restrain Vilgax. They usually are as small as pebbles, but in The Final Battle: Part 2, they were large and sharp, piercing into the floor of a ship before turning into tentacles.

Using his methane abilities, Swampfire can produce spores that can cause whoever is around him to fall asleep.

Swampfire's body can generate a type of mud that sticks to everything but him, which he used to blind Negative Humungousaur, as the latter could not pull it off his eyes and had to change forms.

Swampfire is capable of regenerating and regrowing any damaged or destroyed body parts, allowing him to grow back lost limbs, holes in his body, or even his head. He was even able to reform his body from remains when it got splattered to pieces. He can also reattach detached body parts by manipulating his vine-like "veins" and tentacles to reach out and meld with the insides of the detached limb and return them to the body, allowing him to reconstitute automatically if damaged.

Swampfire's methane has a very pungent smell which is intolerable to some species like the Incurseans, which will make them retch and faint. By spraying methane at a human's face, it will render them unconscious.

Swampfire's "blossomed" form's fire blasting abilities are more powerful than before. He can also grow plants from the ground simply by raising his hand.

Swampfire has enhanced strength, being able to push over a Highbreed Weather Array using leverage by turning his feet into roots running deep into the ground as well as hold his own against Vilgax with his bare fists. In his "blossomed" form, he appears to be even stronger and more durable than before.

Swampfire's body structure allows him to walk straight through thin spaces such as the gaps between iron bars. Also, once, when he was crushed under a large container, his body deformed into vines that burrowed through and then out of the ground to reform him instantly. In the same instance, Kevin punched Swampfire in the torso, resulting in his fist getting stuck in it until Swampfire punched him back.

Swampfire is able to extend his fingers and feet into long roots that can dig through rock.

Swampfire shows the ability to grow vines with a flame tip from his hands and use them as whips.

Weaknesses
Swampfire can be continuously cut up by sharp objects such as Goop's Anti-Gravity Projector, preventing him from regenerating.

Swampfire can be frozen, which renders him immobile. However, he can thaw himself out by igniting the methane in the palms of his hands.

Swampfire cannot control weeds, though after 'blossoming' he gains the ability to command the hordes of Mutant Pumpkins of Anur Transyl.

Similar to Stinkfly, Swampfire's swampy stench makes it hard to hide from anybody or anything capable of smelling.

If Ben turns into Swampfire with a broken limb, his limb will be twisted and shriveled, and he will feel pain from it.

Trivia

 * Swampfire underwent heavy revisions to his design during the pre-production stage of Alien Force, with concept art drawn by Glenn Wong, Eric Canete, Tom Perkins and Glen Murakami. The final design was created by Glen Murakami, with color styling by Chris Hooten.
 * Swampfire's redesign in Omniverse has many similarities to Tom Perkins' original concept art of him.
 * Swampfire is the first alien used in Alien Force. Coincidentally, the first alien used in the original series (Heatblast) also has fire-based powers like Swampfire.
 * Swampfire's voice is very stuffy and nasally because he doesn't have a nose. It also sounds a lot like Maximus from American Dragon: Jake Long.
 * Despite not having a nose, however, Swampfire somehow has a sense of smell.
 * Swampfire is one of the two of Ben's aliens whose natural biological behavior overrides his normal state; the other one being Big Chill, whose Necrofriggian's drive to reproduce also overrides the Omnitrix.
 * Methanosians undergo a kind of growth and "blossoming" phase. 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.
 * Swampfire is the reason why Kevin has an x-shaped scar on his chin.
 * Swampfire has a nano in FusionFall after the player beats Fusion Ben.
