So Bond fandom ought to be a good one for this, because Bond sleeps with the enemy literally every film. The thing is though, he's bad at it? Like I have seen, I think, 2 old Bond films and read one of the Fleming novels, and at no point in any of them could I suspend disbelief that the Bond girl would have willingly slept with him. Ever. Which is why I have not seen any of the other Bond films or read any of the other novels.

Luckily there are also male villains in Bond! And Bond is frequently slashy as hell with them! Not as much fic as you'd think. (The vast majority of Bond slash is Craig-era Bond/Q, which has its charms, but is not really enemyslash even at a stretch, except in the way that any tech support/end user relationship is enemyslash.)

The one that has an always small but very persistent fandom is Bond/Trevelyan. I am, as previously established, not super well-up on canon here, but I believe that in one of the Brosnan movies, one of the main bad guys was a former MI6 agent who had been left for dead while working with Bond on a mission. Bond is understandably dealing with grief over this, because they had been lovers as well as partners in the field. But! It turns out Trevelyan did not die, he defected! He almost asked Bond to defect with him! And now he is the bad guy that Bond must fight. At the end of the movie Trevelyan is falling off a high place and Bond catches him at the last minute and has to decide! whether to let go!

My knowledge of this movie is best expressed by the fact that until today I had no idea Trevelyan was Sean Bean. But the lovers-to-enemies(-to-lovers) is very good. I encountered it very early in my fandom journey, and while there was never a whole lot of fic and I never followed the fandom very closely, it made a big impression.

Unfortunately the fandom is scattered to darkness of night, old recs lists are full of broken links, one of the seminal longfics exists only as an extremely dubious GoogleDocs upload that probably should not be linked on Fanlore but is anyway, etc. etc. But here are a couple I dug up!
