Four Arms

Four Arms is a Tetramand (a play on the Latin "tetra", meaning "four", and "mand", meaning "arms") from Khoros. He is the sixth Omnitrix alien to appear on the series. He first appeared in Washington B.C. when Ben needed to fight the giant mammoth that Dr. Animo reanimated.

Appearance
Four Arms stands at approximately twelve feet in height, has very well developed muscles, two pairs of four-fingered arms, and the Omnitrix symbol on the upper-left shoulder and the Ultimatrixsymbol is on his chest. His skin is bright red and very tough, as though it is armored. The black stubble stripe goes from the bridge of his nose to his neck. A second black stripe goes from his chin to his lower lip, and he has four eyes: a main pair, and a smaller pair below them.

Powers and Abilities
thumb|right|240px|Four Arms transformation in the original series Four Arms is a 12-foot-tall (3.7 m) four-armed, four-eyed powerhouse with armored skin and extremely dense musculature, making him unmatched in pure physical strength. His strength is such that he can create shockwaves simply by pounding the ground or clapping all four of his hands together, dubbed the "Big Smack", and his leg strength allows him to cross entire city blocks in a single jump.

Weaknesses
Sometimes Four Arms' bulk is a disadvantage, all the extra mass of his muscles and heavy skin makes Four Arms relatively slow, and his size likewise makes using things designed for smaller species difficult, especially when enlarging them. When under the effects of an illness, Four Arms's strength and stamina are somewhat lessened and he develops pungent hives in his armpits.
