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

Powers and AbilitiesEdit

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.

Powers and AbilitiesEdit

A Tetramand's most prominent ability is their enhanced strength, courtesy of their quadruple arms. According to Rook Blonko, female Tetramands are traditionally stronger than males. However, she was defeated in combat by Ben Tennyson as Four Arms. It is stated by Ben himself that Tetramands get stronger as they age. According to Duncan Rouleau, Tetramands are stronger than Appoplexians.

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.

Weaknesses Edit

As Khoros' environment has evolved Tetramands into physical powerhouses, the species has sacrificed speed for incredible strength and as such are slow and clumsy. This causes them to be weak against high speed enemies which tend to play against them using their agility and flexibility; a trait Tetramands are greatly incapable of defeating.

Besides making them a huge target, a Tetramand's size also makes it difficult to get inside buildings or walk down a street without knocking things down. Bred for strength, much of the damage they inflict is often purely unintentional, which makes Tetramands almost as dangerous to their allies as they are to their enemies.

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.

Culture Edit

They are a race of bloodthirsty warriors that constantly battle and conquering other tribes, seeking glory and recovering past's relics for an advantage over enemies. The species is currently led by Warlord Gar Red Wind in the original Ben 10 canon and an unnamed overlordess in the reboot.

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.

Technology Edit

Their technology is more of Bronze Age, they wear Greek/roman battle armor clothing and warriors wear gladiator-like clothing. They are specialists of building indestructible Khoros engines and warships and powerful weapons including war sledgehammers and swords.

Omnitrix Transformation Edit

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".
