Queen of the all-robotic Cluster Empire, Vexus (voiced by Eartha Kitt and Cree Summer) is obsessed with the conquest of Earth, under the claim of "liberating robotkind" from the humans. About the only thing that matches her dreams of conquest is her obsession with Jenny, whom Vexus has continuously tried to induct into the Cluster (though with no lasting success). Vexus also has a daughter, Vega (voiced by Thora Birch) who is also among those blinded to the truth, though she and Jenny eventually exposed Vexus for what she truly is.
