Star Trek Online: The Needs of the Many
Kai Kira. A lot can happen in 30+ years, but...

(I would have said the same about Londo and Vir at the start of Babylon 5, though, so I guess I can cope)
Picard and Beverly's kid Rene marrying Riker and Troi's kid Tasha.
The Gorn and the Klingons settling their differences and delaying a war with
a baseball game. My new all-time dumbest TrekLit moment. Ever. I almost drove my palm through my face.
Poor Wolf Dulmer being locked up because he's the only one in the galaxy who remembers all the continuity errors in Star Trek! (I loved that chapter so much!

)
