Chimera Sui Generis

Chimera Sui Generi, also known as Chimerans or Vilgaxians, are a species from the planet Vilgaxia.

Anatomy
Chimera Sui Generi are a green-skinned humanoid species with long squid-like tendrils on their heads. Most females have them on their head, while males have them on their chin or all around their head to resemble hair or beards, respectively.

Powers/Abilities
Chimerans have incredible strength, being able to defeat Tetramands and Vaxasaurians with a single punch, break free from Lepidopterran goo, stop an Arburian Pelarota in sphere form, and lift Cascans and Florauna with their bare hands.

Chimerans possess enhanced durability, being able to easily withstand a Crystalsapien's lasers, a Methanosian's fire blasts, and even an intense heatwave generated by a Pyronite without visible damage. Similarly, their durability can shatter a Petrosapien's arms and even make Galvan injure themselves.

Chimerans possess enhanced reflexes and agility, being able to stop a Kineceleran at full-speed.

Chimerans are possibly quite intelligent, as Myaxx was one of Azmuth's assistants and helped him make the Omnitrix and the cloaking field for Xenon. Meanwhile, Vilgax displays high levels of expertise with the Omnitrix and has vast army of drones that he may have built himself.

Certain Chimerans can shapeshift their arms into powerful tentacles and project powerful laser beams, which can burn Ectonurites and catch up with a Kineceleran, from their eyes.

Chimerans can to speak to and through their own DNA, which was how Vilgax was able to talk to Upgrade when he was merged with Rojo.

Vilgax, the most notable Chimeran Sui Generis featured on-screen, has displayed abilities that other Chimerans are not yet confirmed to possess, including:
 * transforming into a large octopus-like creature, which he referrers to as his true form, while underwater.
 * being immune to radiation, as he can safely pass through a planet's atmosphere.
 * surviving in the vacuum of space, though he used to condition himself to do so without protective gear for brief moments.
 * flying at superhuman speeds.
 * breathing powerful cyclones from his mouth.
 * hearing sounds that are too faint for normal hearing to detect.

Weaknesses
Chimerans are vulnerable to an Earth cold.

A Chimeran's optical lasers can be absorbed by an energy-absorbing species, such as a Fulmini.

As stated by Myaxx, Chimerans are not naturally built for space, meaning that they need oxygen to breath.

There is a limit to how much damage a Chimeran can take, as they are vulnerable to electricity and Omni-Enhanced energy.

Despite his skills on the battlefield, Vilgax can be defeated by the element of surprise. He may also have problems changing from a giant octopus into his conventional humanoid form if severely weakened. In fact, needs to be in water-based environments while in this form.

Omnitrix Transformation
The Omnitrix's Chimera Sui Generis representative is named Gax, who first appeared in the reboot episode "Omni-Tricked: Part 1".

The Omnitrix from the original Ben 10 continuity contained Chimera Sui Generis DNA obtained from Vilgax. However, Ben Tennyson was unable to discover this form because the power surge on the Chimerian Hammer removed the DNA sample from the Omnitrix during the original series episode "Secrets". While Ben wore the original Ultimatrix, it did not contain Chimeran Sui Generis DNA.
