Dimension 23 is an alternate reality that closely parallels with Ben's and is where Ben 23 is from.


In Store 23, Dimension 23 is shown to have a different history from the main dimension. Dimension 23's Bellwood is similar to Ben 10's, but has the Mr. Gyro franchise replacing Mr. Smoothy.

Ben 23 found the "Hero Watch" just like in the original series, but had to teach himself how to use it because his Max passed away before the Omnitrix arrived. Ben uses the Omnitrix for fame and fortune, and believes that all aliens are evil (except for his aliens) until his counterpart Ben Prime arrived in this dimension and changed all that.

    • This is similar to the main dimension's predisposition to green.
  • According to Derrick J. Wyatt:
    • There was a bit about Dimension 23's Kevin working as a busboy in Mr. Gyro.[1]
    • Dimension 23 is also known as Universe 23.[2]
  • Professor Paradox formally called it the 23rd dimension.
