Vexus

Queen of the Cluster Empire. Her goal is to conquer Earth and subjugate the "robocracy," freeing it from human influence. Standing in her way is Jenny Wakeman (XJ-9), a teenage robot created by her mother to protect Earth but who longs to live a normal teenage life. Vexus constantly tries to lure Jenny into her Cluster, sometimes resorting to trickery and manipulation. 2,000 years ago.

An alien robot with insect-like features. She is often depicted in a green and yellow striped color scheme. She has long striped hair (sometimes compared to the crown of an Egyptian pharaoh), an insect-like head with antennae, small wings, and what appears to be a crown with a sphere above her head. Her appearance has changed over time: after escaping Cluster Prime, her body became damaged, later her colors became darker, and in some episodes, she appeared in a green corset, missing her upper torso.

Cruel, she loves to manipulate both her subordinates and her enemies. At the same time, she is very intelligent and inventive.

She can transform into different forms (for example, in the episode "Designing Women," she turned into the robot QT-2 to trick Sheldon). She can fly, teleport, and create portals for travel.
