Ben 10 Alien Forms

Four Arms

Four Arms is the Omnitrix's DNA sample of a Tetramand from the planet Khoros.

Appearance

Ben as Four Arms

Four Arms is a humanoid alien that is approximately twelve feet tall, has well developed muscles, two pairs of four-fingered arms, and red skin. A black stripe goes from his chin to his lower lip, and he has four eyes: a main pair, and a smaller pair below them.

In the original series, Four Arms wears a white T-shirt with a black line going down it, black pants, and fingerless gloves. He wears the Omnitrixsymbol on his upper left shoulder. His eyes are yellow and he has no hair.

In Ultimate Alien, Four Arms wears gold wrist and ankle bands, and wears black underwear that has a gold waistband, as well as two golden sashes that go across his chest. His eyes are green, he has a black ponytail, and he wears the Ultimatrix symbol on his chest.

In Heroes United, Four Arms, in addition to his clothes in Ultimate Alien, wears pants, fingerless gloves, and tattoo like stripes on his body, which are the same as the stripes of his shirt in original, giving him his original series look.

In Omniverse, Four Arms now has three short spikes on the top of his head, a mustache like design, and the black stripe on the top of his head is gone. He has no hair, he has a black tank top like shirt with one large green stripe in the middle, and black pants. He has a belt, where the Omnitrix symbol is located. He also has fingerless gloves like in the original series, with green cuffs at the wrist of his gloves. His skin is also lighter than it was in Ultimate Alien.

11-year-old Ben's Four Arms in Omniverse looks the same as the original series, but now has green eyes and the Omnitrix symbol on his shoulder is now green. In both his 11-year-old and 16-year-old incarnations, Four Arms now appears to have a second set of pectorals for his other set of arms. Four Arms wears his fingerless gloves and the same pants and shirt as the original series.

Ben 10,000 as Four Arms

Four Arms has a better developed forehead, more muscle mass, a different T-shirt design and a pair of jutting incisors.

Four Arms wears the Omnitrix symbol on his chest.

Gwen as Four Arms

Four Arms has darker skin, hair and clothes based on Gwen's, and lacks the vertical black stripe sported by Ben's version. Just like Ben, Gwen wears the Omnitrix symbol on her upper left shoulder.

Powers and Abilities

Four Arms' most prominent ability is his enhanced strength, being able to lift several times his own weight and punch through various resilient materials with ease. His strength allows him to use anything heavy as a weapon, from big rocks he can throw several feet away, to beams and pillars that can be used as clubs. His great strength even extends to his jaws and bite, allowing him to bite metal and damage it.

Four Arms can create strong shockwaves by clapping all four of his hands together or slamming his fists on the ground.

Four Arms can jump several times his own height, at least seven stories up, in a single bound.

Four Arms has high durability, being almost fire and laser-proof.

Weaknesses

Four Arms' bulk sometimes is a disadvantage; all the extra muscle mass makes him relatively slower than other opponents, and his size, likewise, makes using things, or moving through areas designed for smaller species difficult. His immense size also makes him an easy target for enemy attacks.

When under the effects of a cold, Four Arms' strength and stamina are severely reduced, his skin turns from bright red to a dark shade of orange and he develops pungent hives in his armpits.
