Not exactly a fanfic, but there’s a tumblr AU called half dragon Steven that I really like

Its where rose got corruption scars, that look like dragon features, and Steven inherited them, it’s a really interesting AU, and I based my oc off of it

But I also like reading this AU about Steven where his mom was white diamond

The Black pearl comic! it's so freaking good! You can find it on Tapas.io!
