Types of Vampires
In Overlord, the author seems to set tiers for vampires:

Lesser vampire: Reanimates by vampire brides' active skill by spell-casters; a zombie that possessed minimum intellect.

Greater vampire: Reanimates by Shalltear's vampire active skill or by a powerful necromancer; typical vampire, more intellectual and powerful than lesser vampire.

Vampire bride: Transformed by Shalltear's vampire special skill (high-tier vampires); It is an undead that even more powerful than a normal vampires (in WN, Brain receive power boost and spell-casting feat), but Shalltear can only have limited brides with her.

Vampire lord: A title given to a powerful vampire, estimated level 60~70.

Origin Vampire: more like a monstrous undead with very little human quality, origin vampire create other lesser-tier vampires, in general it is impossible for lesser-tiers to become origin, even atavism has limited effect (as hybrid cannot become pure-bred).

True Vampire: It is only exist in Yggdrasil. It is Shalltear's race.
