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 twelve feet tall, has well developed muscles, two pairs of arms with four-fingered hands, 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 Don't Laze Me, Bro, Four Arms wore a sleeveless purple bodysuit, blue gloves and a green wig on his head. He also had two lime green star-shaped tattoos on his upper arms.

Four Arms wears the Omnitrix symbol on his chest.

Billy as Four Arms

Four Arms has four gold bracelets on his wrists, as well as a gold crest on the top of his head, replacing the black stripe. He wears shorts instead of jeans, and his collar is visible.

A squirrel as Four Arms

Four Arms resembles the squirrel in its regular form, but it is much larger and has red fur. It has four red arms with black forearms, along with a bushy tail. It wears a sleeveless white T-shirt with a vertical black stripe, along with black pants.

Gwen as Four Arms

Four Arms looks similar to Ben as Four Arms, but she has a feminine build. She wears a light blue T-shirt with white sleeves and a black cat logo on the chest. There is no black stripe at the top of her head. She has a tuft of orange hair with a blue hairclip on her head.

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. By clapping two of his arms, he only can set aside gas, dust or any air-traveling menace that could hurt him.

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.
