Mad Swampfire is the Power Watch's DNA sample of a Methanosian from the planet Methanos.


Mad Swampfire is a muscular and tall plant-like alien. His skin color is light green, his face is colored yellow, red, and orange, doesn't have pupils and his chin is clearly visible. His hands are colored black, with four orange 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. He wears a black, spiked suit with a large collar raised up around his neck, which is yellow on the inside. The Power Watch symbol is located on his stomach. He also has spikes and orange bandages all across his body.

Powers and Abilities

Mad 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 blasts are precise enough for him to shoot a cage with Kevin and Gwen in it, while the cage melted and Kevin and Gwen were left unharmed.

Before "blossoming", Mad Swampfire's fire blasts are powerful enough to harm Vaxasaurians. In his "blossomed" form, his fire blasts have become more powerful than before. Mad Swampfire is capable of limited flight through means of launching fire from his palms as jet propulsion, much like Heatblast.

Mad Swampfire has a high degree of chlorokinesis being able to telepathically interface with plant life, manipulate and instantly create biological agriculture, and generate a gas that make exposed plant life elongate, enlarge and ensnare enemies, seemingly being mutated by the gases. Some plants have a brief green aura when he influences them.

Aside from Earth plants, Mad Swampfire use his telepathic plant interface with alien plant life, which was what allowed him to free Max from the Highbreed Tree Monster. In his "blossomed" form, his telepathic influence over plants has extended to sentient plant life, such as the Mutant Pumpkins from Anur Transyl.

Mad 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 they can sometimes become larger and sharper if used on a metal surface.

Mad 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.

Another method of regeneration involves reattaching detached body parts. This is accomplished 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.

Mad Swampfire's methane has a very pungent smell that is intolerable to some species like the Incurseans, which will make them retch and faint. Using his methane abilities, Mad Swampfire can produce "sleeping spores" that can render humans unconscious.

Mad 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. Similarly, he was able to pull himself out and resist the gravitational force of a Null Void portal, and even hold his own against Vilgax with his bare fists. In his "blossomed" form, he appears to be even stronger than before.

Mad Swampfire's body structure allows him to walk straight through thin spaces such as the gaps between iron bars. 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 Mad Swampfire in the torso, resulting in his fist getting stuck in it until Swampfire punched him back.

Mad Swampfire is able to extend his fingers and feet into long roots that can dig through rock and can generate vine-like tentacles from his back. Mad Swampfire can also grow plants from the ground simply by raising his hand, though he only gained this ability after "blossoming". Swampfire shows the ability to grow vines with a flame tip from his hands and use them as whips.


Similar to Mad Stinkfly's odor, Mad Swampfire's swampy stench can make it hard for him to hide from anybody or anything capable of smelling.

Despite his regeneration, Mad Swampfire can be continuously cut up by sharp objects, such as a Polymorph's Anti-Gravity Projector, preventing him from regenerating. Mad Swampfire can also be harmed by electricity, such as the attacks of a Conductoid.

Mad Swampfire can be immobilized by ice, such as the ice breath of a Necrofriggian, though he can thaw himself out by igniting the methane in the palms of his hands.

Mad Swampfire's fire attacks can accidentally start a fire, and can be canceled out by fire extinguishers.

Mad Swampfire is vulnerable to magic attacks and his body heat can make it difficult for him to fight opponents that are attracted to heat, like reptiles.

Mad Swampfire can be immobilized and overpowered by the gravity powers of a Galilean, and like other organic beings, Mad Swampfire is vulnerable to being aged to dust by the time rays of a Chronosapien or a Chronian.

Mad Swampfire's plants can be killed using liquid chemicals, and despite his enhanced strength, Swampfire is physically weaker than Crystalsapiens, Tetramands and Vaxasaurians.

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