Well, I can't say much about his specific motive. But who wouldn't take up the chance to turn from a normal evil mastermind to a superhuman evil mastermind?
.....Though I am curious just what he's up to as well.
He pretty much betrayed UNion at airport, and that was one of his plans, to get more power to use it for something? well yeah pretty much the power got extracted from veronica but he stole it before it fades away.
Normal evil person.
