Vexus

"So, this one fancies girl robots, does he?... Then he is going to love me!"

- Vexus

Vexus (formerly known as Queen Vexus) is the former main antagonist of My Life as a Teenage Robot. She is the former master of The Cluster and the archenemy turned allie 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 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 in Hostile Makeover, a robotic nurse in "Tradeshow Showdown", another robot girl named "QT2" in "Designing Women", a girl named "Violet", and as "Vicky" in "Queen Bee".

She was voiced by the late Eartha Kitt, who also played Yzma in The Emperor's New Groove, Agatha K. Plummer in the 1996 film Harriet the Spy, and Catwoman in the 1960s Batman TV series. She is currently voiced by Cree Summer. In Crossy Road: The Series, she was voiced by Grey DeLisle, who also voices Vicky from The Fairly OddParents, Yzma as a teenager in The Emperor's New School, and Zippy in T.U.F.F. Puppy.
