Main Timeline (Classic)

“

Omniverse is always taking place "now." Ultimate Alien is always taking place just before Omniverse. Alien Force was always taking place "now," until Ultimate Alien aired, at which point it took place about a year ago.

”

—Dwayne McDuffie's concept of "now", implying the use of a floating timeline. Due to the nature of a floating timeline, the contents are subject to revision.

The main timeline is where all of the canon Ben 10 episodes take place.

This is timeline where nearly the entire Ben 10 series take place. Ben 10: Race Against Time didn't directly happen in this timeline, and Gwen 10 and Goodbye and Good Riddance are "what if" episodes.
