Ghouls

Ghouls are deceased individuals who have been brought back from the dead under the servitude of their master.

Information
Ghouls are rarely seen in the BlazBlue universe and not much is known about them. They have only been since twice - during the Ikaruga Civil War, and almost immediately following its conclusion. It is known that they cannot die even if they have been decapitated, and the only way to stop them is to either completely destroy them, or to take out the individual controlling them, usually a necromancer. Drugs and Arts can be used to resuscitate someone and bring them back, but they will not survive any trauma to their head. A soul is not required for someone to be reanimated.

Chronologically, the first time they've been seen in the series was when the Ninth Squadron of the Novus Orbis Librarium were sent to investigate a laboratory where a Nox Nyctores was presumed to have been kept. The squadron, consisting of Honoka, Jin Kisaragi, Karengina Palset, and their captain, Grimmwood Hastur, encountered an innumerable amount of corpses that were resurrected when they decided to leave. They were taken out after their necromancer, actually a proxy puppet controlled through the sorcery of Relius Clover, was found and defeated.

The next time they were seen was on the outskirts of the 13th Hierarchical City of Kagutsuchi. They were summoned by Fuzzy to fight Mai Natsume, Bell, Kajun Faycott, Shiori Kirihito, and Taro Sasagae. Some were set alight by Kajun's chemicals but the majority of them were destroyed before they went on to help Ragna the Bloodedge fight off Fuzzy and a Bone Dragon.
