Need ao3 crossover fic recs please

I’ve mostly read fanfic on Wattpad, but I recently started exploring ao3 thanks to a friend’s recommendation. I’ve been really enjoying it so far.

The thing is, I usually stick to whatever my friend recommend because I’m still learning how to navigate ao3. But I really love reading crossover fics, and that’s not really my friend’s style, so I’m hoping to find some recs here.

I’d be happy to read anything. If you have favorites, pretty please share them! Thank you so much!
