Reala is a First-level Nightmaren and one of the primary antagonists of the series. Created along with NiGHTS to be Wizeman's right hand, Reala is obedient towards his creator and leads the Nightmaren army.

As all Nightmaren, Reala is genderless but due to his voice and much more masculine appearance Reala is usually referred to as a male.

Reala and NiGHTS are "siblings" with both equal flying and acrobatic skills. In contrast to NiGHTS' kind and loyal personality, Reala is cruel and insidious. Due to their equal skills and opposing personalities, NiGHTS and Reala are strong rivals.
