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.
- 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 this universe's Azmuth is blue. The Omnitrix is also blue.
- This is similar to the main dimension's predisposition to green.
- According to Derrick J. Wyatt:
- Professor Paradox formally called it the 23rd dimension.
