Vilgax's Hunt for the Omnitrix Arc

Vilgax's Inspiration
Vilgax, a Chimera Sui Generis, is the major villain of the Ben 10 series and the archenemy of Ben Tennyson. He wants the Omnitrix from Ben so that he could he create an army of aliens. However, the incident that inspired Vilgax to hunt for the Omnitrix was because of a Time Paradox. In the year 1773, Vilgax had been exiled from his homeworld Vilgaxia because of disobedience. His ship, the Chimerian Hammer is summoned by a time travelling Chronosapien Maltruant's distress signal. Maltruant praises Vilgax and agrees that if Vilgax helps him to fix his ship, he would give him a Chronosapien Time Bomb. However time travelling Ben Tennyson and Rook Blonko who are after Maltruant so as to stop the Time War along with George Washington infiltrate the area where Vilgax was fixing Maltruant's ship. So as to avoid Vilgax seeing him since he is from the future, Ben transforms into Mole-Statche and along with George battles Maltruant and Vilgax and is further assisted by Rook who is on the Time Cycles. Eventually since Maltruant's ship is fixed he goes back into time as Vilgax escapes, witnessing Ben transforming into another alien, he vows to get the transforming device for himself.
