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
