Timeline Diagram

ExOS is a closed time loop, starting from a variable where Ben either did or didn't meet Ben 10,000 when he was young. Gwen interferes with the past and causes an offshoot of the timeline, A.K.A. The Original Continuity. Thus, making the real series we got technically an offshoot.
ExOS Timeline


  • This series concept came together after Carth was inspired by Elmike9, and his redesigns of Ben 10 aliens in the Original Series style. Later, when Carth would try an OS style Teen Ben, he started getting ideas for his own OS continuation, the first seed of what would become ExOS.
  • ExOS was a working title, but after a while, it just kinda stuck.
  • Every alien who has been in the 5 main Ben 10 cartoons will appear, along with several additional ones to bring the total to 100 aliens by the end of the series.
  • The design half of the project was rebooted on July 12th, 2018, the new designs going under the moniker of "Era 2".
  • The theme song is an edit of an obscure remix of the Original Series theme by UK Bootleg Remix Artist Juxtaposeur, released in 2008 on an online radio station.
  • This series was voted BTFF's June 2019 Featured Series.
  • This series won the 2019 Omniverse Award for Best Still-Running Series.
