Haniman originally worked for the military, designing holographic projectors. However, he lost his job when the military decided that holograms were not important. He decided to show them just what a holographic projector could do, by creating the Night Stalker hoax. He could then make a large profit selling charms to keep the Night Stalker away. Sonic and friends learned about this from him and were soon attacked by the Night Stalker, but it was easily defeated and Tails soon learned that it was a hologram and disabled the projecter. Haniman was exposed for his crimes, and became rejected by his people.
- After defeating the Night Stalker, Haniman references a famous line from Scooby-Doo. He says, "And I would have gotten away with it too, if it weren't for you meddling heroes!".
