Tetramand (a play on the Greek "tetra", meaning "four" and "mand", meaning "arms") are an alien species from the desert planet Khoros.

Tetramands are a buff and bulky species. Most Tetramands are red, but blue and brown ones have been seen. Tetramands have spikes on their arms. They have 2 front toes on each foot. Tetramands appear to have an additional set of smaller pectoral muscles below their primary set to help move their second set of arms.


Generally speaking, Tetramands are aggressive, and are not at all reluctant to use violence.

Because female Tetramands are traditionally stronger than males, they are in turn considered the better warriors, and due to this, if a male Tetramand manages to defeat a female Tetramand, the male becomes the female's chosen husband.

As a Tetramandian custom, the bride collects four items before a wedding: "Something conquered, something bruised, something severed, and something blue."

Tetramands are not very amicable towards outsiders, as in the case of Kevin when he went to get one of their indestructible engine blocks for his car. Initially, he was refused and had to agree to marry Princess Looma in three years to be allowed.

Tetramands are very strict in the upholding of their laws; a person whose crime was merely jumping the turnstiles at an auto show was buried up to his neck in sand.


Female Tetramands can reproduce with male humans.


Tetramands make the toughest and most durable engines in the galaxy.

According to Matt Wayne, "Tetramands seem fairly Bronze Age-y for their level of technology".[1]

Powers and Abilities

Tetramands have four very brawly arms. Due to this, Tetramands have a considerable advantage in close hand-to-hand combat, and while not really martial artists, Tetramands have developed an arsenal of specialized maneuvers that make use of their prodigious physiology, with a heavy emphasis on power blows and grappling holds, and they are able to use a variety of melee and ranged-weapons simultaneously. A favorite move is a sonic wave that is produced by smashing together all four hands concurrently.

Tetramands have dense, armor-plated skin.

With their incredibly strong legs, a Tetramand can jump at a height of several stories.

If a Tetramand is infected with an Earth cold virus, they become significantly weakened in strength and agility, and they get hives under their arm pits.

A Tetramand's size makes them easy targets.
