"I will show you the power of a god. Now... receive my judgment!" - Wizeman the Wicked.

Wizeman the Wicked is a god of the nightmare realm in the night dimension, a place in the subconsciousness of all lifeforms where both dreams & nightmares take place.

Little is known about Wizeman's past, but its said that he was the first intelligent life in the Night Dimension & the creator of the Nightmare realm itself.

Wizeman wants to rule the dreams dimension & open a portal to invade & rule the waking world as well. But to do that, he created dream demons called Nightmarens with the purpose to destroy the world of dreams & to steal dream energy called Ideya from humans during their sleep. Once Wizeman collects enough Ideya, he will be able to open a portal to the waking world & to invade it.

Wizeman created 2 jester-like Nightmarens called NiGHTS & Reala to be his strongest creations, but to his surprise, NiGHTS decided to rebel against him. Since then, Wizeman never managed to succeed achieving his plans, as NiGHTS with the help of Visitors always stop him.

Wizeman's physical form is a strange, humanoid creature, wearing a long dark-blue cape with a spiked metallic crown covering most of his head. He has six metallic floating hands, each one with an eye on the palm.

Wizeman is a very cruel, arrogant, manipulative & cold dictator who has no sympathy nor compassion for anybody, not even for his own creations. If they displease him, he won't think twice about destroying them. He despises every source of light & good; thus he shall stop at nothing to destroy the night dimension & spread darkness to everything.

"Fools like you are beyond hope. All that is left for you is despair and regret" - Wizeman the Wicked

Not even Reala is spared of Wizeman's wrath, even though he is very loyal & hardworking. He does everything to please Wizeman, but Wizeman has never shown any gratitude for his loyalty & hard work. Although it’s unlikely Wizeman would actually destroy Reala due to him being his only loyal First Level Nightmaren & being one of his strongest creations.

Wizeman has an "abusive parent"-like behavior towards NiGHTS, telling NiGHTS to "hold their tongue" when NiGHTS speaks back to him & calling NiGHTS' uprising "infantile disobedience". Wizeman refuses to accept NiGHTS' free will, yet curiously, he never tries to destroy NiGHTS. Instead, he insists on making NiGHTS his minion again. The reasons for that is most likely because NiGHTS is one of Wizeman's strongest creations, being the only First Level Nightmaren other than Reala & because of the possibility that First Level Nightmarens are difficult for him to create.

In contrast to his behavior towards his minions, none of the Nightmarens but Reala appear to like Wizeman neither.

Wizeman is the sole creator of every Nightmaren, though he doesn't have control over his creations will considering NiGHTS uprising. However, if Wizeman is destroyed, all of his creations are as well.
