Yup, I wrote my first Cyclops x Alucard fanfic. (Just a one-shot)
I'd love if you checked it out.

Basically Alucard has a nightmare about his father taking him back to do more experiments on him. And when he wakes up, Cyclops is there to comfort him.
Credit to @hattsoff for the hilarious idea for the ending lol.
