Star Trek: Probability Factor was an announced IDW series of Star Trek comics. This series would have told "What If?" stories based during both the Original Series and Next Generation eras. One example suggested by David Tischman in the announcement in the "Focus on... Star Trek" comic was "What if Natasha Yar had lived?"

It was expected to see publication in 2008.
