This is not just a new species to the crew, but also new to the viewer. I remember in TNG that there were several new aliens; Q, Nagilum, etc.

What other "aliens" did the crew encounter? This would be anything that was a creature who was sentient, another lifeform which had to interact in some way with a character, that might have displayed an ability or an influence or something that says "Hey, I could be a threat!"

Hallucinations or the crew being transformed into things don't count.

I'm especially interested in species where communication between the lifeform and the crew was possible or if the lifeform was otherwise a threat

    Do you count events like when Kirk was split into two? How about where Neelix and Tuvok merged into one? There's a WIDE range of things that can qualify as 'new life'...this question is far too broad.

    I feel like making a list of episodes without "new life" encounters might be easier.

    Not trying to be funny pretty much 80% of Voyager episodes fits this. Enterprise as well. Sep 15, 2017 at 17:58

Taking into account only those episodes where the crew of the Enterprise-D encounter a wholly new lifeform or uncover one that was previously hidden, the crew succeed in their mission to "seek out new life" on no less than 37 occasions.

  • I thought the "jellyfish" from EAF were sentient. Sep 16, 2017 at 15:42
  • What about Where No One Has Gone Before from season 1? There was a lot of stuff they've met on that journey.

  • @doomista - Memory Alpha mentions "energy beings" in the weird blue space thingy, but I can't see anything in the script to indicate that that's what they are...
