Vexus

Vexus (formerly Queen Vexus) was the main antagonist of ''My Life as a Teenage Robot. '' She is the former ruler of The Cluster and the arch enemy of XJ-9/Jenny Wakeman. She has clashed with Jenny many times before, nearly succeding each time but ultimately fails. Her Second-In-Command is Smytus.

She is voiced by the late Eartha Kitt who also played Yzma. She is currently voiced by Cree Summer.

Vexus was the reigning monarch of Cluster Prime and commander of the Cluster, and is still one of XJ-9's most common foes. She rarely gets the upper hand, however. Her name is likely a pun on "vexen".

Vexus and Nora Wakeman have been opponents for what must have been quite some time, though she's been created by Professor B and Vexus was secretly likely the inspiration for XJ-9's creation. XJ-9 typically can outwit and outperform Vexus, but regardless, Vexus' has the resources of an entire planet to call upon, so occasionally she does gain the upper hand- but typically through trickery and sabotage.

She possesses the ability to transform, but typically for means of disguise, compared to the multitude of battle forms that Jenny typically uses. Her known forms are as the photographer, a robotic nurse, another robot girl named "QT2", a girl named "Violet", and as "Vicky".

In the film Escape from Cluster Prime, it was revealed that Vexus had a daughter named Vega.
