Scenario:

I used to be a rather costly mercenary, but I made enough money in that line of work to pursue a most grander ambition. Destroying Jump City and crushing the Teen Titans. I don't have a particular vendetta against the city, the high number of metahumans simply makes for an excellent selection of apprentice candidates. Crime can be a lonely business, I'm simply looking for someone as powerful as me to watch my back... Or take my place when I'm gone. However, I'm content in allowing the Titans to think destruction is all I seek.
