Imagine the Yeerks on Deep Space Nine, adding to the political intrigue of that show. The Federation not only has one major threat, slow infiltration and subjugation by a superior military force of shapeshifting alien xenophobes but infiltration and subjugation by a secret military force of brain-controlling alien parasites. I'd love to see a Yeerk invasion of the Federation, to test their ideals even more.
Well, thoughts?
