Zombie Dragon is an undead that hailed from YGGDRASIL.
Using his unknown special skill, Ainz can create Zombie Dragons from the corpses of any types of dragons that died.
According to Suzuki Satoru, a Zombie Dragon would be several, if not dozens of times more powerful than a zombie made from a human corpse. In addition, its increased HP meant that not even a level 100 player like Suzuki is able to kill one in a single 3rd-tier spell.
- Ainz considered zombie dragons as a famous example of having strong, physical bodies suitable for the creation of zombies.
