Yessss here’s a couple recent ones from a few different fandoms since you didn’t mention which ones and I’m obsessed with many and sort of just rotate fandoms.
Keep Your Friends Close And Your Enemies Closer (Its Easy When They're The Same Person) By Sugarisavegetable
Kissed the brick and then threw it thru my skull (high praise). The straw hats take note of Luffys strange reaction to some names. Of course shenanigans ensue! It stops pre wano and is completed

The Greatest Treasure in Hell by lucky1025
I was shocked how good this crossover was. I went in with zero expectations and got fucking blown away.
Luffy gets sent to heaven and immediately goes “this is boring imma go to hell instead”. He then jumps down to hell and almost lands on Alastor. Who process to get hit with the “I refuse your refusal, and then imma change your entire life for the better”. The rest of the straw hats start showing up and lot of chaos happens! Alastor surprisingly fits right in with the crew and basically runs PR for them it’s hilarious!
It has spoilers for all of hazbin and one piece(at least to post wano). Also both luffy and alastor are very ace in this. A lot of fic totally ignore alastor asexuality (which kills me guys plz I want some evil ace rep) It’s also completed.

Only four chapters but I’m investing early. Sakumo finds “sukea” on the battle field and brings him home. Sukea is a time traveling kakashi

Full metal alchemist x Naruto:
Common sense - jutsu by AmySilver
Ed gets stuck in the Naruto verse and while the ninjas can kick his ass easily the whole fic so far has been…
Ed: ninjas are so fucking stupid because *long rant*
The ninjas spying on him: oh shit, I think we might be stupid

JJK x the summer hikaru died
A Monster Just The Same by LuckyFool2
Basically what’s on the tin! So far it’s really good!! Gojo really just adopts whatever freak of nature he can find.
