Wizeman, also known as Wizeman the Wicked, is the main antagonist from the NiGHTS game series. Wizeman is the creator, leader, and king of evil creatures called the Nightmarens. As the supreme master, ruler, and creator of the world of bad dreams simply called Nightmare, he desires to destroy Nightopia and recreate it in his own image. To achieve this, he created the other Nightmarens to steal Ideya, which would thereby eliminate Nightopia from existence. He is also regarded as the "father" of NiGHTS, Reala, Jackle and possibly all the Nightmarens. He is one of the two main antagonists of the series, with Reala being the second.
Wizeman the Wicked was the first and most powerful Nightmaren of them all. Not only he is the tyrannical master of Nightmare but Wizeman is actually also as well the God of Nightmare, it is said that he is a visitor without any Ideya. Being the creator of evil creatures called Nightmaren, he planned to destroy Nightopia in order to reshape it and to expand his empire of Nightmare. To do this, he decided to steal Red Ideya from sleeping humans. Unfortunately for him, one of his Nightmaren betrays him and vows to stop his evil plans. This Nightmaren is none other than the hero NiGHTS. In the end, Wizeman was finally and completely destroyed and his evil kingdom of Nightmare was no more.
Wizeman's true form is a strange, caped humanoid creature with a spiked metallic ball helmet covering his head since it is shown in NiGHTS into Dreams... that his face is actually quite never seen and he uses the helmet to cover/hide it. He is shown not to have a mouth and he has six eyes on his six metallic flying hands which can fire magic lasers which can also do various dark magic spells. It appears he has a sort of amulet with 2 pieces of Green Ideya and a piece from a Blue Ideya but it is unknown if they are indeed pieces of Ideyas. Wizeman also has a sort of spiked crown on top of his head.
Wizeman appears on the final lap of the Dream Valley track. He interferes by lifting boulders across the track and tossing them at the racers.
In the Nightmare Zone DLC of Sonic Lost World, Wizeman appears in the beginning of the zone when he warps Sonic to Nightmare. One of his hands later appears as the combat platform for Zomom.
