Created by Wizeman, NiGHTS found his fathers plan to turn the Waking World into a living nightmare to be horrible, so he rebelled. NiGHTS is the only Nightmaren to do so.
He was once a partner-in-crime to Reala, stealing dreamers Ideya (positive forms of dream energy made solid; all are virtues: courage, wisdom, growth, hope, and purity.)
NiGHTS was born with the ability to fly; he is rarely seen standing on the ground, if not at all. When flying, his hands emit Twinkle Dust, harmless sparkles that when connected in a circle, create a Paraloop, which sucks anything into an abyss. He also has the ability to Dualize with dreamers. Dualizing allows a human to join their body with NiGHTS, thusly having access to all of his powers. NiGHTS has no gender, so he takes on the gender of whomever he happens to Dualize with.
