During the events of Hack-O-Lantern (1988) played by Hy Pyke
In 1968, Grandpa drives to Tommy's house and honks his horn. Tommy runs outside and Grandpa tells him Happy Halloween and offers him any pumpkin from the back of Grandpa's truck. Grandpa tells Tommy that he is very special and gives him a present and then leaves. Bill arrives at Grandpa's property and sees a group of Witches in the barn. Grandpa surprises Bill and tells him that he shouldn't have come. Bill tells Grandpa to leave Tommy alone and a Witch hits Bill in the head with a hammer and Bill is dragged back to his car and Grandpa pours gasoline on it and tells Bill to burn in Hell before lighting it on fire.
13 years later, Grandpa goes to Tommy's house and gives him a robe and tells him that tonight, Tommy shall learn what power is and then leaves. As Grandpa is driving away, Amanda stops him and tells him to stay away from Tommy and Grandpa tells her that he has great plans for Tommy. Grandpa grabs Amanda and tries to rape her like he did on Amanda and Bill's wedding day. Amanda pulls away and Grandpa angrily drives away.
Grandpa sees Tommy with Nora and tells him that he must be pure for the ceremony that night and then tells Nora to drive Tommy home. Grandpa drives to where the Halloween party is going to be and tells Vera that he is dropping off some pumpkins. Grandpa then comments on how attractive Vera is growing up to be. He tries to give her a hug and Brian steps in between them. Grandpa threatens Brian and Vera tells Brian who her Grandpa is. Roger drives up and briefly talks to Grandpa before Grandpa drives away.
Grandpa and the other Witches have a ceremony and share the blood of a goat. They then initiate Branding Witch into the coven and brand her with a pentagram. Vera goes to Grandpa's barn. She goes inside and starts yelling at Tommy about him murdering Brian. Grandpa tells her that she has intruded on the sacred blood ceremony and has the other Witches grab her. Grandpa tells Tommy to kill Vera, but Tommy frees her. Grandpa tells Tommy that he has failed Satan and excommunicates Tommy.
At the party, Vera runs out of the restroom and goes to who she thinks is Tommy in the robe, but is Grandpa. The person in the devil costume come out of the restroom and they and Grandpa fight. The person in the devil costume stabs Grandpa in the chest with a cultivator. Roger rides up to the building and Grandpa tells Roger that the power is in the blood and puts his hand on Roger's face and then dies.
