Alucard from Kouta Hirano's Hellsing, works well at 0.95 weight. Use adetailer for better eyes/facial features.
Use "Red coat" "White collared shirt" "Black pants" "Red Ascot" to generate his normal outfit. You can also generate his glasses with "round eyewear" "orange-tinted eyewear" and "glasses"
Recommend adding "greyscale" "high contrast" and "monochrome" in negative prompt.
NOTE: AnimeBoysXL was used for the preview images, I found this to be the best model to capture the character's overall likeness.
