As Paradox described: like the way branches "branch" off a tree trunk, timelines branch off the main one. More often than not, those branches also have branches, so on and so forth. Dimension 23, though oddly named, parallels with our Ben 10's, AKA, Ben Prime. This story follows through the obstacles Ben 23 faces as he encounters various versions of himself, all a result of a fateful story unique to their own while all still being a Ben 23.
