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 and the dates are subject to revision.[DM 1]

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

This is the 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.

The Beginning

  • The Universe had been created by the Contemelia and the Slimebiotes started their lifelong mission of seeding life across the growing universe.
  • The Timeline at the beginning started to branch into many timelines and shift creating its own Timestream.
  • Realities began to diverge.

Prior to 231AD

  • Millions of years prior to Omniverse
  • Before 231AD
    • Azmuth is born.
