|First Appearance||Store 23|
Ben 23 found the Omnitrix (or as he calls it "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 10 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 are blue. The Omnitrix is also blue where the main dimension's Omnitrix is green.
- According to Derrick J. Wyatt:
- Professor Paradox formally called it the 23rd dimension.
