Ben 10: Secret of the Omnitrix2007

Tetrax:
I know what you're goin' through. I was young. I didn't care about anybody but myself, so it made sense that I wound up a mercenary, a soldier for hire. I was loyal to whoever paid me the most, no matter how evil they were. It was only a matter of time before I would work for the worst of the worst - Vilgax. I stole the last piece of the puzzle Vilgax needed to invade my home world. When my people didn't bow at his feet, he destroyed the entire planet to make an example out of it. Vilgax did the dirty work, but he couldn't have done it without my help.
