Crossovers

Avengers/Good Omens

This Long Game Is Not For Outsiders by TardisIsTheOnlyWayToTravel
Her name isn't really Darcy, of course: her true name is something much older and a damn lot more powerful.

Norse gods weren't the only supernatural beings in New Mexico when Thor was there. Clever and adorable Avengers/Good Omens fusion. There's also a sequel that reimagines the movie in this context: Against a Common Enemy

Avengers/Star Trek Reboot

Secondhand Hope by flyakate
Avengers/Trek Reboot fusion with some good banter. In which Tony gets excited by alien tech.

*

Spider-Man/The West Wing

Let Parker Be Parker by lonelywalker
In an age of costumed heroes and alien invasions, Ben Parker is the President America needs - a reassuring presence in the White House, and a hero to the West Wing staff. His nephew Peter, however... With Ben Parker in the White House, it's all CJ can do to keep his nephew Peter out of the papers. It's the West Wing/Spider-man crossover you never knew you wanted but which you totally do, because Ben Parker=Martin Sheen=Jed Bartlet and everything just falls into place once you realize that. <3

Avengers/Arrow

Bad Altitude by Frea_O
Fun crossover where Felicity Smoak and Natasha Romanoff are trapped together on a plane that looks like it's going to crash.
