Vilgaxia is the Chimera Sui Generis homeworld, located in a system of planets called the Shadow Realm.[pop-up 1][1][merch 1]


Vilgaxia's Landscape

Prior to Alien Force

Vilgax emerged from the Shadow Realm several centuries ago and left a trail of destruction in his wake.[merch 2] At some point, Vilgax gained control of his home planet and changed its name to Vilgaxia.[DM 1]

Alien Force

Vilgaxia was introduced in Ghost Town, where Zs'Skayr attacked Vilgaxia, possessing all the citizens and turning them into his Ectonurite slaves. After several vain attempts to stop the infestation (including alternating the planet's sun constitution so its light would weaken Ectonurites), Vilgax escaped Vilgaxia and asked for Ben's help. Despite their differences, Ben accepted and after some complications, freed the planet from Zs'Skayr's control. As an agreement between them, Ben promised to not tell anyone what happened there, and Vilgax gained credit for Zs'Skayr's defeat.


Vilgaxia in Omniverse as seen on Attea's screen

Vilgaxia was mentioned and briefly seen in Vilgax Must Croak, when Milleous attempted to capture the planet. However, he was unable to; due to Attea's failure in killing Vilgax, the citizens learned about the incident and put up a massive resistance, forcing the Incurseans to retreat.


The Vilgaxia Symbol

Little has been revealed about Vilgaxia so far. Vilgaxia includes a large city with a large, fortress-like palace, home to its current ruler, Vilgax.

The atmosphere is teal in color, temporarily dark orange during Ghost Town, and looks as if the surface is underwater. Closer to the horizon the atmosphere fades and reveals space. The atmosphere also makes it impossible to see the terrain when the planet is viewed from space.

Some of the known terrain consists of light green mountain ranges.

  • Vilgaxia has at least two moons.
  • Citizens of Vilgaxia have their own opinions whether Vilgax is a hero or otherwise. However, nobody voices their thoughts publicly for sure.[DM 2]
    • For example, Milleous claims that capturing Vilgax would demoralise the people of Vilgaxia enough to make them surrender. When the news is out that Vilgax succeeded in escaping, the Chimerans put up such a fight that the Incurseans were forced to retreat.[2]
  • Vilgaxia's insignia is similar to the insignia of the Marvel Comics terrorist organization Hydra.
