Threshold

Stardate 49373.4: Torres, Kim, and Paris work as a team to cross the transwarp threshold and travel at warp 10, a theoretical impossibility which would allow the traveler to occupy all points in space simultaneously. Though the attempt is successful, Paris’ biochemistry undergoes a massive change which causes him to mutate into a more evolved version of humanity. The new Paris kidnaps Janeway and they both cross the barrier in the shuttle, precipitating more changes in both of them.
