Ben 23 is a hero in Death of Ben 10. He first appeared in Chapter 8. He is a Human from the planet Earth and wields his dimensions version of the Omnitrix, dubbed the 'Hero Watch'. He exists in Earth-1010/Dimension 23.


Ben 23 appears physically identical to a fourteen year old Ben Prime. The most obvious difference between them is that this Ben's favourite colour, and thus the colour most present in his outfit, is blue.


This Ben is cocky and self assured. He always acts as though he is on camera.

Powers and Abilities

He wields the Dimension 23 equivalent of the Prototype Omnitrix. However, as part of his showman ship and 'character' he keeps all but 23 of his transformations locked at any given time to keep the roster fresh and appealing to his fans. He will briefly have a 24th transformation available whenever he unlocks a new form.


Limiting his available transformations can cause him to be ill-equipped for any given scenario. Thanks to the amount of variation 23 aliens allow, this is rarely a problem.

Ben 23 is an irritable showman, constantly giving his 'audience' a good show, whether or not there is anyone there. His annoying personality can often land him in trouble with others.


All events depicting Ben 23 in Ben 10: Omniverse occurred to this version of Ben 23. He fought alongside Ben Prime, Professor Paradox, and No Watch Ben during the Eon Crisis.

Death of Ben 10

Ben 23 is the second alternate Omnitrix wielder recruited by Professor Paradox to help save Ben Prime from Apollo in Chapter 8. He saved Mad Ben from the Wasteland Thugs, and removed the Omnitrix-restricting brace from his arm.

He helped storm San Diego Ironworks, defeated Apollo 23, helped defeat Ollopa, and later helped defeat Apollo Prime.


Death of Ben 10


  • Having never gotten rid of his Omnitrix when he was twelve like Ben Prime did, Ben 23 possesses most of Ben Prime's aliens, plus some aliens Ben Prime has yet to unlock.
