overlord thanatos doesn't exist, it's "overlord wiseman" and "grim reaper thanatos" ainz talk about them in volume 7 chapter 4, they are the most powerful undead that ainz can create with their lvl 90.

I don't think ST will about the race overlord, overlord is the last evolution of skeleton mage and for NW just a death knight is a legendary undead so a overlord must be a god undead for them.

Just a theory, I have read somewhere that the most powerful of the six gods was a undead like ainz maybe he was a overlord and with time the meaning of overlord had change
