Halloween Wizard

Halloween Wizard is the name of a very elderly, red-robed, dark, magical wizard. He lives inside of a large, supposedly haunted mansion, which was egged by Rigby due to him turning off the light when being asked by Rigby to give him candy in Terror Tales of the Park. He later lurked around Pops's House and used his dark magic to turn Rigby into a nice-looking house. Later that night when it was dark, Muscle Man was on the porch and saw him driving his car to the front of the house. Muscle Man tells him to change Rigby back and to get out of there but refused so Muscle Man loads his shotgun telling him not to ask twice. The Halloween Wizard then teases him and asks Muscle Man if he has any clever jokes about his mom, Muscle Man tells him not to talk about his mom so he starts to shoot the gun. Everyone else watches him shooting the gun but Muscle Man is tripped and falls. The wizard then drags him across the grass and Muscle Man starts to squeal and holds his gun up in the air while being taken and shoots the gun a few more times before he goes into the woods. Mordecai, shocked, asks if they saw that. Then there's knocking on the door, it opens and it's Muscle Man who has had his skin ripped off, showing only muscle. Muscle Man says,'I told you I was ripped,"then falls over and dies after that and scares the others then the phone rings. High-Five Ghost goes to answer it, after Skips tells him not to, and answers the phone saying,"Hello?". The wizard then says "Good-bye!" and sucks him into the phone and turns him into liquid that squirts into Mordecai and Skips. Mordecai is then knocked unconscious when the wizard throws him against the bookshelf. Benson and Pops see this and they both scream and run into different rooms. Then the wizard breaks Skips' crossbow and the wizard throws Skips into the chimney and burns him. Then he goes to the bathroom and pulls back the curtains for the shower and finds Benson and says,"What's up Gumball?". Benson then screams and gets flushed down the toilet. Then, Pops is on the bed terrified and the wizard comes in and Pops fires a rock at the wizard with his slingshot but misses and the wizard picks him up, drags him on the ceiling, and puts him in the closet which disappears. Rigby is scared and asks if anyone was there. Mordecai then wakes up and tells him that he won't let anything happen to him but the wizard cuts his head off. Then Rigby finds out that Mordecai has died and he says sorry to the wizard. Then the wizard comes and gives Rigby his pushmient by throwing eggs at him. Then Rigby is mad because the wizard turned him into a house and killed everyone so he can egg Rigby.The wizard then drowns him in a giant raw egg. It is revealed that it was just a story that Rigby told. Muscle Man then makes fun of his story saying that it was weak and that his story about wrecking cars in a pit was way better. But Rigby says that "that's not it" and turns out to be the wizard who disguised himself as Rigby. Everyone else is freaked out and screams as the wizard finishes the episode by saying, "Happy Halloween!".

Powers and Abilities
Despite his old age and insanity, the Halloween Wizard is one of the most powerful villian to appear in Regular Show. While several characters, objects and even mundane situations in the show displayed some sort of supernatural skill, Halloween Wizard shows to be powerful enough to turn Rigby into a house, kill all the other main characters with ease (even the undead High-Five Ghost), levitate, and shapeshift. He also seems to be imune to physical assault as he show no injurie after Muscle Man shot several times on him (though it's possible that he healed or that Muscle Man simply missed him).

Trivia

 * He is also credited as "Wind", such as when Muscle Man got off of Rigby's (as a house) porch.
 * He more than likely will only appear in Terror Tales of the Park due to him being named Halloween Wizard.
