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]

Dimension 23's name comes from The Number 23, a film about a man who becomes obsessed with the 23 enigma once he reads about it in a strange book that seemingly mirrors his own life.[DJW 9][DJW 10]

The name is also a reference to the 23 enigma, a belief in the significance of the number 23. It suggests that the number 23 appears with unusual frequency in various contexts and may be a symbol of some larger, hidden significance.
