Vexus rules the Cluster, basically a robot supremacist empire that goes around invading and enslaving other planets. The Cluster beefs with Jenny because Earth is one of the nuts they've yet to crack, and Jenny's it's current defender. Vexus's initial strategy was to try to tempt Jenny to abandon Earth and join the Cluster, promising a better life outside the servitude of organics.
Also Cluster Prime is actually a pretty great place for its citizens, though they are fed a bunch of propaganda about Jenny being a traitor to robotkind. Though Vexus did steal a vital component from its citizens that allowed access to shape-changing and weaponry, and blamed it all on Jenny as well, in an effort to mitigate the chances of a potential uprising.
