Hellwood is the Proto-Ultimatrix's DNA sample of a Methanosian from the planet Methanos.
Hellwood is a humanoid, plant-like alien that has an overall green and orange colored body, mostly with a green flame-patterned head and root-like feet. His red eyes are oval-shaped with points at each end. Also, his shoulders and head have green petals and his elbows and legs have green frills sticking out. Hellwood is taller than an average human and has a distinct rotten stench that worsens with heat. He wears the Proto-Ultimatrix symbol on his chest.
Powers and Abilities
Hellwood has the ability to ignite methane in his palms similar to a flamethrower. His fire blasts are very precise.
Before "blossoming", Hellwood's fire blasts are powerful enough to harm Vaxasaurians. In his "blossomed" form, his fire blasts have become more powerful than before. Hellwood is capable of limited flight through means of launching fire from his palms as jet propulsion, much like Soul Burner.
Hellwood 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, Hellwood use his telepathic plant interface with alien plant life, which was what allowed Swampfire to free Max from the Highbreed Tree Monster. In Ben's "blossomed" form, his telepathic influence over plants has extended to sentient plant life, such as the Mutant Pumpkins from Anur Transyl.
Hellwood 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.
Hellwood 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.
Hellwood'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, Hellwood can produce "sleeping spores" that can render humans unconscious.
Hellwood has enhanced strength, as Swampfire was 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.
Hellwood's body structure allows him to walk straight through thin spaces such as the gaps between iron bars.
Hellwood 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. Hellwood can also grow plants from the ground simply by raising his hand, though he only gained this ability after "blossoming". Hellwood shows the ability to grow vines with a flame tip from his hands and use them as whips.
Hellwood's swampy stench can make it hard for him to hide from anybody or anything capable of smelling.
Despite his regeneration, Hellwood can be continuously cut up by sharp objects, such as a Polymorph's Anti-Gravity Projector, preventing him from regenerating. Hellwood can also be harmed by electricity, such as the attacks of a Conductoid.
Hellwood 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.
Hellwood's fire attacks can accidentally start a fire, and can be canceled out by fire extinguishers.
Hellwood 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.
Hellwood can be immobilized and overpowered by the gravity powers of a Galilean, and like other organic beings, Hellwood is vulnerable to being aged to dust by the time rays of a Chronosapien or a Chronian.
Hellwood's plants can be killed using liquid chemicals, and despite his enhanced strength, Hellwood is physically weaker than Crystalsapiens, Tetramands and Vaxasaurians.
If Albedo turns into Hellwood with a broken limb, his limb will be twisted and shriveled, and he will feel pain from it.
Ultimate Hellwood is the Proto-Ultimatrix's DNA sample of an Evolved Methanosian from the planet Methanos.
Ultimate Hellwood has the appearance of a humanoid tree instead of a walking plant like Hellwood. Ultimate Hellwood's body is dark brown in color, and now has three blue gooey shells containing an organic, blue-colored gel-like solution of napalm on each of his arms and a large one on his back. His face is made out of parts of wood. Ultimate Hellwood's body is composed of petrified wood. He also has that napalm gas coming out of his head. He wears the Proto-Ultimatrix symbol on his chest.
Powers and Abilities
Ultimate Hellwood can ignite methane in his hands using his napalm to generate blue-colored flames that are about three times hotter than Hellwood's, as they can melt through a brick wall.
Ultimate Hellwood can produce a larger and stronger blast of fire when he puts his hands together. He can also propel himself underwater and in the air, the latter further indicating that he can breath underwater.
Ultimate Hellwood is more resistant to damage than Hellwood and has lethal fire bombs on his arms which he can throw as weapons. He can shoot blue methane projectiles from his hands that can multiply into small blue gas bombs that explode on impact.
Ultimate Hellwood retains Hellwood's abilities to generate seeds and vines and seems to be a lot faster than he looks, as seen when he snuck up behind Eon so fast that he was unable to notice him.
Ultimate Hellwood is vulnerable to electricity, such as that generated by an Amperi.
Like other organic beings, Ultimate Hellwood is vulnerable to being aged to dust by the time rays of a Chronosapien or a Chronian.
