Four Arms

Fourarms is the Codon Stream's DNA sample of a Tetramand (pronounced Tet-Rah-man-d)(a play on latin tetra meaning four and mand meaning arms) from Khoros (Khor-ose). It is the sixth alien to appear on the series. It was also Ben's most used alien form when he was his younger self, since that was Ben's favorite fighting style back then. Fourarms was first unlocked in the episode Washington B.C..

Abilities
Fourarms possesses tremendous strength and nearly limitless endurance. His strength is such that he can create shockwaves simply by smashing the ground or clapping all four hands together, dubbed the "Big Smack". Fourarms' muscular legs also allow him to leap several city blocks at a time.

Weaknesses
Sometimes Fourarms' bulk is a disadvantage, since the Tetramand species sacrifices speed for strength and cannot run for long distances or at great speeds. Fourarms' size also makes him unable to hide anywhere or sneak behind anyone.

When Ben had a cold, Fourarms turned orange and had stinky hives. Strangely, when Ben tries to change into Fourarms, the Omnitrix seems to nearly always change into a different alien. This may be the AI of the Omnitrix which uses more strategy than Ben, who simply likes smashing people.

Appearance
Fourarms stands at approximately twelve feet in height, has very well developed muscle, and four three-fingered arms, with two on each side, with the Omnitrix symbol on his upper right shoulder. His skin is bright red and very tough, almost armored. A black stripe goes from the bridge of his nose to his neck (and possibly down his entire spine). A second black strip goes from his chin to his lower lip, and he has four eyes: a main set, and a smaller set below them. All four are enteirely orange and glossy. His Ben 10,000 form has a better developed forehead, more muscle mass, no sleeves, and a pair of jutting incisors. The Omnitrix symbol has moves to his chest.



Planet
Tetramands are giants compared to most species, standing ten feet on average. The harsh wasteland of their home planet, Khoros, has turned the Tetramand race into physical powerhouses, a trait that is personified in Fourarms.
