Dimension 23 (also known as Universe 23[DJW 1] and the 23rd Dimension[1][2]) is an alternate reality that closely parallels with Ben's. It is the home dimension of Ben 23.


Dimension 23 has a different history than 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.[3]

Notable Inhabitants

Notable Visitors


  • Dimension 23 has a certain predisposition toward the color blue. Many objects are blue, Ben 23's aliens have blue features, and the eyes of Ben 23 and Azmuth are blue. The Omnitrix is also blue.
    • This is similar to the main dimension's predisposition to green.
    • The out-of-universe reason for this is that the crew wanted to use the different color to represent the difference between Dimension 23 and the main dimension.[DJW 2]
  • Dimension 23 may not be accurately named.[DJW 3]
  • Dimension 23's Gwen is shy.[DJW 4] Unlike her Prime Timeline counterpart, she is not an Anodite.[DJW 5]
  • Dimension 23's Kevin works as a busboy in Mr. Gyro.[DJW 6]
  • Dimension 23's Jimmy Jones is just a little kid.[DJW 7]
  • Dimension 23's Billy Billions is on the Ben 23 Inc. board of directors and is growing up fine.[DJW 8]
  • Dimension 23 does not have a counterpart to Malware[DJW 9] or the Nemetrix.[DJW 10]
  • Much like the Prime Timeline, Dimension 23 has Magic.[DJW 11]
  • There are definitely alternate versions of other Cartoon Network characters living in Dimension 23.[DJW 12]
