Tetramand

Tetramands are a red-skinned humanoid species from the desert planet Khoros.

Anatomy
Tetramands are four-armed humanoids standing between 10 and 12 feet tall. Though their dense skin is generally colored red, there have been Tetramands seen with other skin colors including dark pink, blue, purple, and brown.

Female Tetramands have hair. Male Tetramands have hair that turns gray as they get older, but most of them lack hair.

Younger Tetramands are skinnier than adults and have disproportionately larger eyes and heads.

Tetramands can grow to be as tall as 15 feet high. Female Tetramands are usually taller than the males.

Powers and Abilities
A Tetramand's most prominent ability is their enhanced strength, courtesy of their quadruple arms. It has been stated by Ben Tennyson that Tetramands get stronger as they age and by Rook Blonko that female Tetramands are usually stronger than males.

In comparison to other species, Tetramands are physically stronger than Methanosians, Appoplexians, and Vaxasaurians.

Built for battle, Tetramands can take punishment thanks to their tough and thorny skin. This level of durability makes them fireproof and laser-proof.

With their incredibly strong legs, a Tetramand can leap blocks at a time at a height of several stories.

While not necessarily martial artists, Tetramands have developed an arsenal of specialized maneuvers that makes use of their prodigious physiology.

A favorite move is the "Big Smack", a sonic wave produced by clapping all four hands together at the same time. This move stuns an opponent into submission before a blow can even be landed.

Due to the alterations Kevin Levin has made to the Antitrix, Quad Smack is stronger and more powerful than ordinary Tetramands.

Omni-Enhanced Tetramands gain an extra pair of fists and rock-like armor, increasing their natural strength and durability. The electrical hands can double their punching impact and deploy Omni-Enhanced energy while fighting.

Weaknesses
As Khoros' environment has evolved Tetramands into physical powerhouses, they can be slow and clumsy. They can also be constraint by their large size, making it difficult to get inside buildings or walk down a street without knocking things down.

Tetramands are weak against high-speed enemies, which tend to play against them using their agility and flexibility.

Much of the damage a Tetramand can inflict is often purely unintentional, making almost as dangerous to their allies as they are to their enemies. Despite their enhanced strength, they are physically weaker than Evolved Arachnichimps.

There is a clear limit to a Tetramand's durability, as they can strain their hands punching the armor plating generated by Bashmouth's Species.

If under the effects of an Earth cold, a Tetramand's natural strength and stamina are severely reduced. Their skin will turn into a dark shade of orange, pungent hives will develop in their armpits, and they will sneeze out sprays of slimy snot from his mouth.

Behavior
Tetramands are bloodthirsty warriors that constantly battle and conquering other tribes, seeking glory and recovering past's relics for an advantage over enemies.

Similar to humans, Tetramands are extremely emotional creatures by nature.

Society
When forming alliance or receiving weapons, they must prove their worth by combat. If a male challenger defeats Warlord Gar's daughter, Princess Red Looma, not only the winner received the possession he fought for but will also be married to the princess in three Earth years. Female Tetramands are loyal to the strongest male that defeated them and set to marry him.

Although Tetramands are led by Warlord Gar Red Wind in the original continuity, they are alternatively led by an unnamed overlordess in the reboot continuity.

Technology
Tetramands are specialists of building indestructible engines and warships. They are also capable of making powerful weapons, including war sledgehammers and swords.

Omnitrix Transformation
The Omnitrix's Tetramand representative is named Four Arms, who first appeared in the original series episode "Washington BC". Four Arms has appeared in almost every series except Alien Force.

The Ben Tennyson of Dimension 23 has an equivalent of Four Arms named Handy Man, who first appeared in the Omniverse episode "It's A Mad, Mad, Mad Ben World Part 2".

The reboot version of Kevin 11 has a mutant hybrid equivalent of Four Arms named Quad Smack, who first appeared in the episode "Which Watch".

Four Arms has also been used by the Prime Timeline Kevin, the "What-If" Gwen 10, Ben 10,000, the Ben 10 Franklin version of Benjamin Franklin, the Alpha Nanite, the reboot versions of Gwen and Billy Billions, and a squirrel.

Four Arms is available in Mad Ben's Omnitrix, as glimpsed in the Omniverse episode "It's a Mad, Mad, Mad Ben World: Part 2".
