So, clearly the geekiest option is actually Worf, Geordi, Iron Man, and Thor beaming down to a planet to fight Godzilla and the Transformers. The most terrifying thing to me is that as I think of it, I'm also (unintentionally, I assure you) coming up with a plot to make that all (barely) work - clearly the Decepticons have been taken over by the Borg, who have also started bizarre breeding experiments culminating in Godzilla, who is (of course) cyborged so the Borg can make him more aggressive by messing with what little brain he has.
