Swampfire

Swampfire is the form of Methanosian sample in the Codon Stream used by Ben in Alien Force and Ultimate Alien as well as the first alien used by Ben in Alien Force. He was used in the episode Ben 10 Returns: Part 1.

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 connected to rocks. Also, the top portion of his body has red petals same as the color of his head. His species is taller than that of a average human, and has a distinct rotten smell that only worsens with heat and/or fire. His voices is very stuffy and nasally because he has no nose (confirmed by Dwayne McDuffie). His Omnitrix/Ultimatrix symbol is on the center of his chest.



Abilities
Swampfire has the power to control fire and plants. He is able to reattach severed body parts and/or regenerate them with ease. His fire abilities include throwing fireballs, shooting flamethrowers, releasing heated air, immunity to fire, and burn enemies with a ring a fire as shown in Vilgax Attacks. His plant controlling powers include controlling outside plants, spraying methane gas, vine generation, burrowing underground and from one place to another as tall plant-like structures, and seed bombs that once thrown, grow into a flurry of vines and plants that are under his control. He is also shown to have superhuman strength and semi-invulnerability. Also, shown by Albedo in The Final Battle Part 1, he can spray sleeping powder that knocks his foes out cold.

Weakness
Swampfire, although, being able to control fire has a slight disadvantage. He is more vulnerable than Heatblast to ice, because he can be frozen for immense periods of time, and Heatblast is completely invulnerable to ice/cold. This is shown when Albedo transformed into Big Chill he was able to freeze Swampfire. However, this attack created little distraction as Ben broke free using a similar method that he used during the first Highbreed invasion. He ignited the methane in his wrists and broke free when Albedo least expected it. thumb|300px|right

Ultimate Alien
He makes his first reappearance in Hit 'Em Where They Live as he fights off Vulkanus. He reappears again in Video Games accidentally when he wanted to turn into Chromastone to fight The Stalker. Again in Andreas’ Fault he helps fight a lot of Forever Knights then escape. In Ultimate Aggregor he appears for a second to turn Ultimate. He made another appearance in Perplexahedron to melt Gwen back. His was seen in The Forge of Creation to turn Ultimate and fight Aggregor. In Eye of the Beholder he was seen to fight the Sentinels when he went ultimate.
