Star Trek: RealitiesEdit
Realities was a "what-if?" comic series planned by Marvel Comics. At least two stories were planned before it was cancelled:
- "What if Gul Dukat had become the Emissary?", by Andy Mangels and Michael Martin, would have featured the destruction of the Enterprise, the victory of the Borg, and a lead into a sequel.

Star Trek: SpecialEdit
Wildstorm Comics produced a one-shot short anthology entitled Star Trek Special, containing comic stories from the first four Star Trek television series. Star Trek Communicator writer Rich Handley was slated to write a story for that edition and submitted two entries ("The Needs of the Few," about Spock on Romulus, and "The Barber of Seville," about Mot the Barber). However, his story was cut due to space constraints.
When Tokyopop first acquired their license to produce Star Trek manga comics in 2004 they planned to publish a TNG. They later opted to start with TOS instead, as that series' 40th Anniversary was approaching. Prior to that change of plans they announced what they had planned for TNG:
- A "creepy space spider story" by Mike Barr
- A "holodeck story with Worf in Feudal Japan" by Jake Forbes
- A "Q story where he’s split into three personalities" by Chris Dows
- Skin Deep - a "Klingon battle story" by Jim Alexander
- A Mirror Universe tale by Mark Paniccia
Tokyopop did eventually publish a TNG book in 2009, but none of these stories were included in it.

Probability Factor was to have been a TOS and TNG comic miniseries published by IDW Publishing in 2008. The series would have consisted of "What if?" stories based on episodes of the two TV series looking at what might have been if a detail had been changed, "What if Tasha Yar had lived" for example. The featured episodes would have been nominated and voted for by the fans.
The series was announced in the form of a would be fax from David Tischman to IDW's editors Chris Ryall and Dan Taylor, printed in the behind-the-scenes book Focus on... Star Trek. However nothing more was ever announced about the series after that initial tease.
