Wizeman (also called Wizeman the Wicked) is the creator of Nightmare and its inhabitants, the nightmaren. He is the main villian of NiGHTS Into Dreams and NiGHTS: Journey of Dreams.
In NiGHTS into Dreams, he created both Reala and NiGHTS to be his first level nightmaren. When NiGHTS rebelled, Wizeman locked him away in an Ideya Palace as punishment. He is simply defeated at the end by NiGHTS dualized with Claris and Elliot.
In the sequel, like most other characters, he is given a voice. He is immensely furious at NiGHTS for disobeying him, and constantly sends Reala out to bring him back. In the true ending of NiGHTS: Journey of Dreams, he is finally done away with, but not before warning NiGHTS of the cost: that destroying him destroys everything he has made, in other words NiGHTS. NiGHTS never heeded this warning, saying he knew of this all along.
Being a comic book adaptation of the first game, his role has not changed much. The only difference is that he is destroyed at the end of the first arc, with Reala taking over once he's gone. One of his hands is used by Reala to keep an eye on NiGHTS while he is in the real world.
Wizeman is the cruel, heartless dictator of nightmare. He despises all that is good and decent, and sends his Nightmaren out to steal Ideya, as doing so would allow him to destroy Nightopia and arise from the realm of the subconscious. He is so heartless and evil that he cares for no one, as he often gets rid of the Nightmaren who fail him. He also seems determined to get NiGHTS back on his side, however, evidenced by him sparing the rebel Nightmaren (by locking him away or attempting to replace his consciousness) instead of destroying him.
- Wizeman appears in Sonic Pinball Party, both in story mode (as a Egg Cup Competitor) and in the NiGHTS table (as the final boss).
