Grim Reaper Thanatos (具現した死の神) is a powerful undead from YGGDRASIL that can be summoned by Ainz.



Grim Reaper Thanatos is a level 90 undead that was considered by Ainz to be stronger than any NPC mercenary summoned from the Great Tomb of Nazarick with YGGDRASIL gold. According to Ainz, he could only summon one Grim Reaper Thanatos at a time since they were very powerful.[1]


  • Grim Reaper Thanatos is one of the powerful undead that could be created using Ainz's special skill, the kind which required the consumption of his experience points to make.[2]
