She also has no problem with using Jenny's loved ones as hostages in order to get away with her goal, going further as threatening to hurt a human child like Tucker, so she could "consolate" herself from her failed plan. She is also shown to be hypocritical and dishonest on her actions, as she and the Cluster in general insist humans are unjustly controlling Earth's machines, however, she is the tyrant herself in reality, and gladly uses mind control to force those same machines to join the Cluster, willing or not. Vexus is also pretty determined on her goals, even after losing to Jenny too many times before and after losing her status as Queen, she is still sure on attacking Jenny in any chance of defeating or making join her.
