Vilgax

"I have come too far to be denied! The Omnitrix shall be mine, and there is not a being in the galaxy that dare stand in my way!"

- Vilgax first quote in the series. "I am Vilgax, Conqueror of Worlds!"

- Vilgax.

Vilgax is the overall main antagonist of the Ben 10 franchise.

He is Ben Tennyson's arch-nemesis and a Chimera Sui Generis conqueror that has conquered many planets and wishes to claim the Omnitrix for himself and conquer the entire universe. He is a past enemy of Max Tennyson and, later, would become the enemy of Ben Tennyson, once he finds out that Ben wields the Omnitrix.

In the original series and Ben 10: Omniverse, he was voiced by Steven Blum, who also played Starscream, The Green Goblin, Reptile, Zs'Skayr, Ares, Lucifer, Makucha, Orochimaru, Zabuza Momochi, Killer Croc, Lord Darcia III, Amon, BlackWarGreymon and Megidramon.

Personality
Extremely cruel, arrogant, authoritative, and power-hungry, Vilgax is always intent on his goal of ruling the universe, namely through obtaining the Omnitrix, which he views as the ultimate weapon. Vilgax is also very deceiving and manipulative, so as to accomplish his goals and has little to no sense of mercy. He can be considered as a foil to Ben Tennyson, as while Ben Tennyson is rather comedic and is usually looking out for others, Vilgax is always portrayed a serious character and only looks out for himself, with the exception of his own race.

Alternative Timeline
