Methanosian

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

Anatomy
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.

Powers/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. This is accomplished by breaking down rotting plant matter in their stomachs. Their pyrokinetic abilities become more powerful as they age.

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. As they age, their chlorokinetic abilities are slightly modified so that they can control sentient plant life.

Methanosians are strong enough to push down a large Highbreed weather tower, and become stronger as they age.

Methanosians can reattach and regenerate missing body parts.

Methanosians undergo a metamorphosis process that results in them "blossoming". As a result, their natural enhanced durability is amplified so they can take more hits.

Weaknesses
Methanosians have a swampy stench which other beings find repulsive, 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, Methanosians are physically weaker than Crystalsapiens, Tetramands, and Vaxasaurians.

Like other organic beings, Methanosians can be aged to dust by the time rays of a Chronosapien or Chronian.

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

Planets controlled by Methanosians can be killed by certain chemicals.

Behavior
Methanosians have stuffy voices because they do not have noses. However, they do possess a sense of smell.

History
Methanosians are descended from carnivorous swamp plants, but evolved into plant-like herbivorous humanoids at some point in their evolution.

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.
