Tetramand

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

Anatomy
Tetramands are four-armed humanoids with dense skin standing between 10 and 12 feet tall (~ 3.04 - 3.65 m). Female Tetramands have hair. Male Tetramands may 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.

Some Tetramands can grow to be as tall as 15 feet high (~ 4.57 m) as they dominate and win battles over time. Female Tetramands are usually taller than the males.

Although their skin is traditionally colored red, Tetramands can come in other colors. For example, Tetramands from Dimension 23 have dark pink skin, Kolar has blue skin, Quad Smack and Benjamin Franklin's Four Arms have purple skin, and the Tetramand Prisoner has brown skin.

When under the effects of an Earth cold, a Tetramand's skin will turn into a dark shade of orange.

Ecology
The reason Tetramands have multiple arms is so they can fight off giant predators on Khoros, such as Sand Rippers.

Powers and abilities
A Tetramand's most prominent ability is their enhanced strength, being able to lift and throw a variety of beings such as Chronosapiens, Petrosapiens, Incurseans, Lepidopterrans, Loboans, and Vulpimancers. Technically speaking, Tetramands are physically stronger than Methanosians, Appoplexians, and Vaxasaurians.

According to Ben Tennyson and Rook Blonko, Tetramands become stronger as they age yet females are usually stronger than males. However, due to the alterations Kevin Levin has made to the Antitrix, Quad Smack is stronger and more powerful than ordinary Tetramands.

Built for battle, Tetramands can take enough punishment to withstand even a Talpaedan's drills thanks to their tough and thorny skin. Similarly, their skin makes them both fireproof and laser-proof. For Omni-Enhanced and Omni-Kix Tetramands, their natural durability increases thanks to their respective armors.

Tetramands can survive in extremely hot and cold environments, such as those found on Mikd'lty.

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 physique.

A Tetramand's 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.

Tetramands have considerable reflexes, being able to react to speed-based species such as Kinecelerans, Citrakayahs, and Skidmarx's Species.

Omni-Enhanced Tetramands gain an extra pair of hands made of Omni-Enhanced energy, which can double their natural strength and punching impact.

Similar to Fulmini, Omni-Enhanced Tetramands can deploy Omni-Enhanced energy while fighting.

Omni-Kix Tetramands can launch any of their fists from their arms like rockets and reattach them at will.

When under the effects of an Earth cold, Tetramands can accidentally sneeze out sprays of slimy snot from their mouths.

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.

Much of the damage a Tetramand can inflict is often purely unintentional, making them almost as dangerous to their allies as they are to their enemies.

Despite their enhanced strength, Tetramands are physically weaker than Chimera Sui Generi, Evolved Arachnichimps, and especially Evolved Vaxasaurians.

Tetramands can be trapped by the plasma generated by an Insectoid or a DNAlien's slime spit.

Despite their durable skin, Tetramands can strain their hands punching the armor plating generated by Bashmouth's Species.

There is a limit to the fireproof qualities of a Tetramand's skin, as they can "soak [solar] heat like a sponge". They can also be harmed by a Prypiatosian-B's radioactive blasts.

Tetramands are vulnerable to electricity, such as that generated by Gimlinopithecus, Nosedeenians, and Weatherheads.

Tetramands can be easily overpowered by a Celestialsapien's telekinesis.

If under the effects of an Earth cold, a Tetramand's strength and stamina are severely reduced. They will also have pungent hives develop in their armpits.

Unless they maintain their health as they age, a Tetramand's stamina will put them at a disadvantage. In turn, this will make them vulnerable to back pain.

Culture and society
Khoros is a dusty and barberic world where survival is a constant struggle. Due to this type of conflict, the Tetramands' culture has long since devolved, turning from a confederation of thriving city-states into scorched and boundless wastelands.

Tetramands are bloodthirsty warriors that constantly battle and conquer other tribes, seeking glory and recovering past's relics for an advantage over enemies. Known Tetramand leaders include Warlord Gar Red Wind and an unnamed overlordess.

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

When forming alliances or receiving weapons, Tetramands must prove their worth by combat. If a male challenger defeats Warlord Gar's daughter, Princess Red Looma, not only the winner receives 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.

Tetramands are a spacefaring race that are a part of galactic society. They may either settle on any number of worlds and raise a family or live their lives on starships that rarely, if ever, return home to Khoros.

Tetramands live in very close-knit family tribes and defend their kin to the death.

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

History
According to Azmuth's father, Tetramands visited Earth during ancient Egyptian times and built the pyramids. Further evidence shows they worked alongside Humans and (temporarily) two Galvan.

A year after Ben Tennyson found the Omnitrix, a Tetramand was captured by Servantis and the Rooters and became the donor of Manny Armstrong's alien DNA.

The Tetramands once mistook a Lepidopterran exploration party for invaders and tried to fight them off. However, both sides were at a draw in the battle. Though Lepidopterrans were too fast for them to hit, the Tetramand's incredible skills with spears rendered the Lepidopterrans' goo blasts ineffective. The battle ended when the Lepidopterrans fled Khoros.

The Tetramands sought out a challenge to conquer Fulmas in an attempt of glory. Unfortunately, there was no challenge waiting for them because the planet had been abandoned by the Fulmini.
