I can only think of older games that fit the title, and to be honest, I don't think any of them are really horror-class games.
Stufflikehearts - He is a Sith Lord. I love Blood Lord :3
Jeffffey - Blood, you look at the information someone says, look over what really happened, and reply in a way that makes them realize what they were really thinking.
Light10s - Blood Lord! Your avatars are becoming more epic. You make me feel like getting on all fours and submitting my loyalty and obedience to you.
Fievel - Numerous campaigns and conquests, countless bodies decaying after the abandonment of victorious battlefields. Such is the life of Blood Lord.
Dusk_Imp - Blood Lord is like a celebrity here. Everything he does is pure awesome. ALL HAIL BLOOD LORD
Doctress Who - Why couldn't there be a Blood Lord in every forum? It would make life so much easier.
