Vilgax
The galaxy's most feared warlord, obsessed with stealing the power of the Omnitrix.
Vilgax is a Chimera Sui Generis warlord and Ben Tennyson's first and most recurring arch-nemesis. His goal is to obtain the Omnitrix and use it to build an army of soldiers who can transform at his command.
Lore & Background
His ruthlessness, cruelty and hunger for power got Vilgax exiled from his home world. For most of the first season of the original series he lies injured in a regeneration chamber and sends bounty hunters such as Kraab, SixSix and Tetrax Shard after the Omnitrix; once healed he is cybernetically enhanced, with colossal size, strength and durability. In Alien Force he loses to Ben in "Vengeance of Vilgax" and is banished from Earth, then returns in "The Final Battle", where Ben destroys the Omnitrix to keep it from him. In Ultimate Alien a cult mistakes him for the entity Dagon, whose power he absorbs before Ben defeats him with the sword Ascalon. In Omniverse he allies with Eon, then betrays him and sets off the Chronosapien Time Bomb.
