Star Trek: 10 Worst Alternate Realities We've Seen (So Far)
1. Space Vampires And Nazis
The Temporal Wars strike again, this time using that time-honoured collection of evil bastards, the Nazis. Vosk, and his fellow Na'kuhl, slip back to Earth of the 1940s, ally themselves with the Nazis, and lead a takeover of the planet.
