Alright friends, if I was trying to make a blood-themed #DnD dungeon, what creatures fit that theme?

Vampires/V. Spawn, obviously, but what else has blood drain ability?

I’ve got Stirges & Death Kiss beholder-kin & Vampiric Mists; what else can you think of? If you're open to third party content, @KoboldPress has some blood-themed critters in the Creature Codex, the blood zombie and blood elemental at least. As well as some variant takes on vampires if you want to change it up or vary the CR from your normal vampire/spawn.
