The Red-Face Demon is a tall, muscular being with black skin, coarse fur on his legs, dark cloven hooves and a devilish tail. It is unclear what the significance of the song is to the residents the Further. A boy from the Further is seen dancing to the same song earlier in the film. In the first movie, he is seen listening to it while sharpening his nails. One of the Demon's most interesting quirks is his odd love of Tiny Tim's "Tip-Toe Through the Tulips". During Dalton's imprisonment in the Demon's Lair, Dalton was chained to the floor, left alone, adding that the Demon can be both physically and mentally abusive to children. The Demon is a malevolent, ruthless and cruel individual who never gives up on his goal to take a child's soul however, he failed to take Dalton when he finds his body in the real world, though the Demon eventually moves on to a new victim. The Demon hurts Dalton whenever he makes noise. It also seems to enjoy sharpening its nails. The Demon has marionettes which it likes to play with. The Demon keeps Dalton close by in his home in the Further, which seems to be a theater-like chamber.
Lorraine claimed she could still hear its voice, implying that the Demon has a chilling voice. When asked what it wants, it responded that it wanted Dalton. When asked who it was, it responded that it was a visitor. Though the Demon never speaks in the film, it is capable of speaking, as Lorraine mentions that in a dream she spoke to it and it responded to her in words. As she looks at the place where her dog is barking, the Demon pops out behind her. She finds her husband's sweater folded on the bed and smiles until her dog begins barking in the darkness. He appears at the end of the prequel Insidious: Chapter 3, also in a cameo appearance, when Elise returns home and prepares for bed. It shows that he took control of a little girl named Allison and scaring Elise as his crackling shadow was shown behind Allison's chair. The Red-faced Demon makes a cameo appearance in the end of Insidious Chapter 2. Dalton runs from the room, being chased by the Demon, but manages to escape. Dalton hides in his parents bedroom but the Demon's clawed hand reaches out from under the bed and grabs Dalton. Dalton and Josh run for their lives out of the Lair while the Demon pursues them.
When Josh enters the Further, he makes his way into the Demon's Lair and reunites with Dalton before unchaining him from the floor, but he is caught by the Demon, who is in the opposite room sharpening his claws, and attacks the two. He lures him to the Further and manages to capture him (shown by Dalton drawing pictures of the Demon and the Red Door that leads to his lair) and chain him to the floor, where Dalton was presumably tortured and harmed. In the film Insidious, the Demon targets Dalton Lambert, a child that has the supernatural ability to astral project, because of his innocence and his spiritual energy.
