Methanosian

Methanosians are a floral sapient species from the swamp planet Methanos.

Appearance
Methanosians are plant-like humanoids with a green and black body, root-like feet seemingly holding rocks, red and yellow petals on their shoulders and four or five-fingered hands.

Methanosians can come in other colors such as aqua, grey, and yellow.

Biology
Methanosians are descended from carnivorous swamp plants, but evolved into plant-like herbivorous humanoids at some point in their evolution. They can break down rotting plant matter in their stomachs to produce flammable methane that can be used for their fire attacks.

Early Evolution
Methanosians undergo a metamorphosis process that results in them "blossoming". As a result, their pyrokinesis, enhanced strength, and natural durability are amplified. Their chlorokinesis, meanwhile, is modified so that they can control sentient plant life.

Abilities
Similar to Pyronites, Methanosians can generate and blast flames of various amounts of heat and intensity through their hands and mouths via igniting the methane in their bodies.

Similar to Florauna, Methanosians are capable of different feats of chlorokinesis, such as telepathically interfacing with plant life, manipulating agriculture, generating seeds, and sprouting vines as both tentacles and whips.

Methanosians are strong enough to push down a large Highbreed weather tower.

Methanosians can reattach and regenerate missing body parts.

Weaknesses
Methanosians have a swampy stench which other beings (especially Incurseans) will find repulsive. This is due to their race coming from a swamp planet.

Similar to Pyronites, a Methanosian's fire attacks can be canceled by water or fire extinguishers. They can also be temporarily immobilized by ice, until they thaw themselves using their fire powers.

Methanosians are vulnerable to electricity, such as a Conductoid's attacks.

Despite their enhanced strength, according to Dwayne McDuffie, Methanosians are physically weaker than Crystalsapiens, Tetramands, and Vaxasaurians.

Methanosians can be easily overpowered by a Galilean's gravity powers.

Planets controlled by Methanosians can be killed by certain chemicals.

Omnitrix Transformation
The Omnitrix's Methanosian representative is named Swampfire, who first appeared in the Alien Force episode "Ben 10 Returns: Part 1". Swampfire has appeared in almost every subsequent series except the reboot.

The Ben Tennyson of Dimension 23 has an equivalent of Swampfire named Mr. Mucky, who was confirmed to exist by unused artwork from Omniverse.

Swampfire has also been used by Albedo, Vilgax's Bioid army, the Ben 10 Franklin version of Benjamin Franklin, and Anur-Mirrored Ben.
