Overlord is probably like a secondary race available within YGGDRASIL for Lich characters only. If you look at all Nazarick members NPC or not, they have the primary race classification of "Heteromorphic Race" which means they have two forms/races. If you look at other western-fantasy themed RPGs, normally, undead skeletons have classes like skeleton warriors, skeleton mages, etc. Liches are basically powerful mages who've reached immortality by one way or another (Momonga in Overlord was based off a Dungeons & Dragons Lich, which is then based on the creature of the same name. Refer to https://en.wikipedia.org/wiki/Lich and https://en.wikipedia.org/wiki/Lich_%28Dungeons_%26_Dragons%29). One would surmise that the Overlord race is like the strongest form of a Lich in YGGDRASIL.

An interesting note about Liches and Momonga/Ainz is that he has a visible red orb on his abs/navel (or where it should be), which is probably his Phylactery (read the D&D info from wikipedia about Liches).

Additionally, if you've read/watched Strike the Blood, and alchemist named Nina Adelard (and her enemy Wiseman) both have gained eternal live through having their souls put into Phylacterys. They have human forms by connecting said Phylactery (in the form of a small round red gem) into a liquid metal-like substance (a.k.a. wiseman's blood w/c iirc was made of flesh and bones), and can change looks/shape at will.

Although it's my speculation alone, there's a possibility for this idea to come up in later LN volumes, where Ainz could make his own flesh and blood body and transfer to it using his red orb core.
