Vilgax

Vilgax is a powerful and enhanced demon-like Chimera Sui Generis from the planet Vilgaxia and the archenemy of Ben Tennyson.

Appearance
Vilgax resembles an ordinary Chimera Sui Generis, except for the fact that he has battle armor to distinguish himself from the rest of his kind. He has also enhanced his own natural DNA with visible implant injectors, making himself more powerful than ever.

While serving Dagon as his "herald", Vilgax had the color scheme of a Lucubra.

Powers and abilities
Vilgax possesses incredible strength at a level similar to Thanos, being able to break free from Lepidopterran goo and stop an Arburian Pelarota in sphere form. He has also been shown lifting Cascans, Florauna, and Chronians with his bare hands.

In comparison to other species, Vilgax is physically stronger than Tetramands, Vaxasaurians, Zaroffians, and even most other Chimerans.

Vilgax possesses enhanced durability, being able to withstand a Crystalsapien's lasers and make a Petrosapien shatter their arms and a Galvan injure themselves.

Vilgax has fireproof skin, being able to withstand a Methanosian's fire blasts. He can even survive an intense heatwave generated by a Pyronite without visible damage. Correlating with this, Vilgax appears to be immune to radiation, being able to safely pass through a planet's atmosphere.

Vilgax possesses enhanced reflexes and agility, being able to stop a Kineceleran at full speed and sneak up on an Oryctini.

Vilgax can shapeshift his arms into powerful tentacles and project powerful laser beams from his eyes which can burn Ectonurites and catch up with a Kineceleran.

Vilgax is quite intelligent, displaying high levels of expertise and knowledge of the Omnitrix, other species, and their home planets. He is also in command of a vast army of drones that he may have built himself.

Vilgax can transform into a large octopus-like creature while underwater; however, no other Chimeran has been seen doing this.

Vilgax can speak to and through his own DNA, which he used to speak to Ben while he was merged with Rojo as Upgrade.

Unlike other Chimerans, Vilgax can survive in the vacuum of space. In the past, he used to condition himself to do so without protective gear for brief moments.

Vilgax used to be able to fly at superhuman speeds, but lost this ability after being defeated by Ben using Ascalon.

Vilgax used to be able to breath powerful cyclones from his mouth; he also lost this ability after being defeated by Ben using Ascalon.

Vilgax possesses enhanced hearing, being able to hear sounds that are too faint for normal hearing to detect.

While he was in the service of Dagon, Vilgax could project and manipulate energy from his hands and eyes. He could also move between Dagon's dimension and back, similar to the Esoterica.

While wearing Malware's remains as battle armor, Vilgax gained the abilities of Galvanic Mechamorphs and had access to every piece of technology Malware modified his biology with. His durability was also increased to be able to withstand the nuclear energy generated by Atomix's Species.

Vilgax formerly owned several weapons, such as the Ruby Ray of Rouleau, the Shield of Seagel, and a ray gun. The only weapon he currently carries is his personal sword.

Weaknesses
There a limited extent as to how much damage Vilgax can take. His size can makes it difficult to fit into small entrances.

Despite his skills on the battlefield, Vilgax can be defeated by the element of surprise.

Vilgax can be captured in a cage created by a Fulmini using their Omni-Enhanced energy. He can also be easily overpowered by the telekinesis of a Fulmini of the High Override's size.

Vilgax can experience fear in the presence of Ma Vreedle, as he tried to battle Ben only to retreat once she showed up. He is also afraid of the faces of Toepick's Species.

Vilgax may have problems changing from a giant octopus into his conventional humanoid form if severely weakened. He needs to be in water-based environments while in this form.
