Fizooz is a spirit who is being held against his will by Azma and his spirit thugs. Azma believes that Fizooz owes him a debt from his former life, and won't let Fizooz leave until he pays for the supposed debt.
"Fizooz. Fizooz. Who...are you?"
"Wife? I...don't remember having a wife."
- Fizooz looks like the enemy Ghosts.
- A book from Crypt 4, The Spirit Within reveals that Fizooz and all other spirits aren't actually the minds of the departed, but rather, something created unconsciously by telepaths themselves. Fizooz and other spirits are simply telepaths' internal mental processes manifesting externally.
