Four Arms is the Omnitrix MK10's DNA sample of a Tetramand from the planet Khoros.


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 New Omniverse, Four Arms now has one short spike on the top of his head, and the black stripe on the top of his head is back. He still has no hair, he has a green tank top like shirt with one large black stripe in the middle, and black pants. He has a belt, where the Omnitrix MK10 symbol is located. He also has fingerless gloves(two green;two black) 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.

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.


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 as seen in Side Effects.
