First Appearance 99 For A Change

Professor Paradox is a time traveling professor, who forgot his true name while being trapped in a separate reality and took this alias after it was suggested by Ben Tennyson and company. He is the Earth-32 version of the canon Professor Paradox.


Paradox has his Alien Force/Ultimate Alien appearance and his Omniverse appearance, depending on which time period he comes from.


His personality is largely unchanged from his Alien Force/Ultimate Alien/Omniverse one.



When Paradox conducted his experiment back in the 1950's, he was thrown into the event horizon. Unbeknownst to him, however, was that the rest of his dimensional counterparts conducted the experiment at the exact same time. As a result, the infinite versions of Paradox merged into one being and it is the true reason he became insane for almost 10,000 years.

Ben 10: Omnitrix Unlimited

Paradox made his reappearance in 99 For A Change. He informed Ben and co. about the upcoming Time War.

In Ben Quest, Paradox helped several alternate versions of Ben defeat mutant versions of Vilgax and Agreggor.

In Ben 10: Across the 23rd Dimension, Paradox transported Ben and Azmuth to the past of Dimension 23 to avert a terrible future and later helped the heroes exploit MAL.W.A.R.E.'s weakness. At this point, he has already entered the war and gives more details to Ben and co. about it.

In Lights Out, he transports Ben Tennyson of Dimension 3000 to Dimension 1 and advices Ben and co. to visit the Antimatter Universe and find the Ben of that dimension as soon as possible.

Edge of Time War

In The Future is Now, Paradox hid Dimension 8543's version of the Omnitrix and briefly fought with Eon.
