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

In this timeline, all of the canon Ben 10 episodes take place.

It is the timeline where nearly the entire Ben 10 series take place. Gwen 10, Goodbye and Good Riddance, Ken 10, Ben 10: Race Against Time and all of the video games released as well as comics didn't happen in this timeline.
