Methanosians are a humanoid plant species from the planet Methanos.

Their evolved counterparts are Evolved Methanosians.


Methanosians are a humanoid plant-like alien species with a green and black colored body with root-like feet, seemingly holding rocks. Also, their shoulders and head have red and yellow petals. Methanosians can either have four or five fingers.

Methanosians are taller than an average human and have a distinct rotten stench that worsens with heat.

So far, only male Methanosians have been seen, so it is unknown what female Methanosians look like.

Before they hit puberty, they have black faces and their petals and facial structure are different. But at the age of 16 Earth years, they slowly blossom in their mature form.[1]


Methanosians evolved from carnivorous swamp plants.

At some point, Methanosians evolved into herbivores.

Powers and Abilities

Similar to Pyronites, they can generate and blast flames of various amounts of heat and intensity through their hands and mouths via igniting the methane in their bodies. Their fire blasts are powerful enough to harm Vaxasaurians and Sonorosians, after they blossom, their fire blasts are stronger than before. Methanosian's fire blasts are also precise enough to melt a metal cage without harming the people inside.[2]

Similar to Floraunas, Methanosians are capable of different feats of chlorokinesis,[DJW 1] such as telepathically interfacing with plant life, manipulating agriculture, generating seeds, and sprouting vines as both tentacles and whips.

A Methanosian's methane is strong enough to knock a human unconscious.[3]

Methanosians are capable of limited flight through means of launching fire from their palms as jet propulsion.[4]

Methanosians are capable of regenerating and regrowing any damaged or destroyed body parts, allowing them to grow back lost limbs, holes in their body, or even their head. They can even reform their body from remains when if they get splattered to pieces.[5]

Another method of regeneration involves reattaching detached body parts. This is accomplished by manipulating their vine-like "veins" and tentacles to reach out and meld with the insides of the detached limb and return them to the body, allowing them to reconstitute automatically if damaged.[6]

Methanosians' methane have a very pungent smell that is intolerable to some species like the Incurseans, which will make them retch and faint.[2]

Methanosians have a form of enhanced speed.[7]

Methanosians are able to extend their fingers and feet into long roots that can dig through rock.[8]

Methanosians are capable of jumping exceptionally high.[9]

Methanosians have strong teeth that can injure each other.[1]

Methanosians can generate vine-like tentacles from their backs.[10]

Methanosians can grow plants from the ground simply by raising their hands, though they can only do this after "blossoming".[1]

Methanosians can grow vines with a flame tip from their hands and use them as whips.[11]

Methanosians are immensely strong, and can root themselves in the ground to push over large targets. This feat in shown by Swampfire when he roots himself in the ground to push over the Highbreed weather tower.[9]

Methanosians can change the density of their body and become malleable enough to pass through metal bars.[2]


Despite their regeneration, Methanosians can be continuously cut up by sharp objects, such as a Polymorph's Anti-Gravity Projector, preventing them from regenerating.[5]

Methanosians can be harmed by electricity, such as that generated by a Conductoid.[11]

Methanosians can be immobilized by ice, such as the ice breath of a Necrofriggian, though they can thaw themselves out by igniting the methane in the palms of their hands.[12]

Methanosians are vulnerable to magic attacks.[1]

Methanosians can be immobilized and overpowered by the gravity powers of a Galilean.[11]

Methanosians cannot control sentient plants, let alone weeds.[13] This is no longer a weakness once they "blossom".[1]

Like other organic beings, Methanosians are vulnerable to being aged to dust by the time rays of a Chronosapien or a Chronian.[14]

Despite their enhanced durability, Methanosians can feel pain from being bitten by another Methanosian.[1]

Despite their enhanced strength, Methanosians are physically weaker than Crystalsapiens,[DM 1] Tetramands, and Vaxasaurians.[DM 2]

Video Games

In the Ben 10: Alien Force (Video Game) timeline, Methanosians can channel their flames into a concentrated fireball or fire beam, tunnel underground and burst in a coating of flames.

In the Ben 10 Alien Force: Vilgax Attacks timeline, Methanosians are capable igniting their hands for "flaming fists", creating a ring of fire, and causing thorny vines to sprout from the ground.

In the Cosmic Destruction timeline, Methanosians are able to ignite plants they are controlling.

Notable Methanosians

Notable Methanosian Hybrids


The name Methanosian is a play on methane.


  • Methanosian blooming reflects the blooming practices of real-life flowers.
  • Sevenseven is scared of Methanosians.[DM 3]
