Four Arms

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

Ben as Four Arms
Four Arms is a humanoid alien that is approximately 12 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 Omnitrix symbol on his upper left shoulder. His eyes are yellow and 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 going 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, he wears pants, fingerless gloves, and tattoo like stripes on his body, which are the same as the stripes of his shirt in original series, giving him the look of Four Arms in the original series.

In Omniverse, Four Arms now has three short spikes on the top of his head, a mustache like design, 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 but his sleeves are gone, showing more muscles.

Gwen as Four Arms
Four Arms has darker red skin then Ben's Four Arms and she has Gwen's hair.

Four Arms wears clothes based on Gwen's. She wears the Omnitrix symbol on her 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.

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.

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

Weaknesses
Sometimes Four Arms' bulk is a disadvantage; all the extra muscle mass makes him relatively slow, and his size, likewise, makes using things designed for smaller species difficult.

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