Unhinged Sirius

Hello all!

I'm looking for fics that feature Sirius leaning more into his darkness and bitchiness. He is my favourite character and a lot of the newer depictions of him seem to water down his general bastardry into something boring or a weak, feminine prop for Remus.

I'm a-okay with angst and graphic violence but I'd prefer not to be recommended any fics with Sirius/ any of the golden trio era kids or any with Sirius being an awful brother to Regulus (I love them being somewhat wholesome)

Cheers!
