Lipstick-Face Demon

The The Red Face Demon or The Man with the Fire in His Face is the main antagonist of the Insidious film series. It/He has first appeared as the main antagonist in the first film of the series, and later returns as a major antagonist in Insidious: Chapter 2, Insidious Chapter 3 and The Last Key.

In the first film, it was the entity in the Further, over which he is ruling with a complete iron hand, and it was the one closest to capturing Dalton's physical body. The demon lives inside a large, red lit, demonically-decorated lair behind a blood-red door in Lambert's attic.

Biography
Being a Demon, He was created as an angel to serve God, however, he rebelled against God and was cast out of Heaven along with all the other demons in ancient times. However, as all other demons went to Hell, he went on to rule the Further, a place between Heaven and Hell.

Personality
Little is known about him except that he is a malevolent and violent entity. He seems to be quite territorial, as only his victims and subordinates are ever seen in his lair. According to Elise, demons such as him would only want to possess a body in order to cause pain to others.

Appearance
The Red Face Demon is a monstrous and sinister creature; tall and gaunt, with a dark humanoid figure. Most of his body is black as coal, with long spider-like fingernails, hooves and a long forked tail. His head is mostly bald except for long tufts of hair around his ears. Although he does not wear any sort of clothing, he often wears silvery metallic claws over his own fingers.

His most characteristic trait is his blood red face, which greatly stands out from the rest of his body. His visage has very strong features, with a prominent aquiline nose, shinning yellow eyes, crooked teeth and a long forked tongue.

Abilities
As a natural demon, he seems to be much more powerful than other simple human souls. He commands his own portion of the Further, which denotes greater might than other weaker entities. Despite his slender figure, he is capable of sending grown adults flying with a brutal backhand hit. He also displays remarkable telekinetic powers, blasting people off with a roar or tripping people in the distance with a nod of his hand.

When possessing physical bodies, even if only partially, he can channel a greater degree of power than other regular souls in the physical world, blasting people sitting around a table by just slamming his conduit's hand on it or by thrashing adult men with no apparent effort. Him being the closest to possess Dalton's body is a testament to his superior strength when compared to other human aspirants.

Insidious
The first manifestation of the demon is when Renai hears it talk through the baby monitor. She hears something saying "...I want it NOW!" loudly into the monitor. It is assumed this is actually the demon and it is implied that he wants Dalton's body. Dalton's spirit is captured by the Demon in his sleep the next night (which is why Dalton does not respond to any type of stimuli like doctors would expect). The demon was able to do this because, as Elise later explains, "Dalton thinks his astral projections are dreams, and it is this lack of fear that led him to travel a bit too far..." (in the world of The Further). It is assumed that Dalton somehow entered the area in the Further where the demon was able to take control of him.

The demon later appears behind Josh and roars menacingly, frightening his mother Lorraine. It disappears into Dalton's room and ransacks it completely.

Josh volunteers to enter the Further to rescue his son Dalton, who is found chained to the floor in the demon's lair. As the demon sharpens his claws while listening to Tiny Tim's "Tiptoe Through the Tulips" from a bronze phonograph, Josh frees Dalton. The demon senses Josh's presence and gives chase to the two; however, Josh succeeds and returns Dalton to his body in the material world. The demon, having lost his connection to Dalton, is unable to reappear.

Insidious: Chapter 2
At the very end of Insidious Chapter 2, Elise hears a sound coming from behind Allison in the shadows that can be implied to have been the Red-Faced Demon, as it made a creaking noise. Hinting that he somehow escaped the Further again.

Insidious: Chapter 3
The Red-Faced Demon appears at the very end of Insidious: Chapter 3 when Elise comes home. She finds Jack's sweater missing from its hanger and instead folded on her bed. She smiles, but her dog begins barking at a face that appears through an open door. as she stares at the face, the demon appears behind her. This occurs before the first Insidious as it is a prequel.

Insidious: The Last Key
Arriving back home after her investigation in Five Keys, New Mexico, Elise dreams of the Lambert family residence and their son whom she had earlier accidentally encountered while traversing the Further. By Dalton's bed, the Red-Faced Demon appears, looking in through the window. Directly after this, Elise wakes up and is called by Lorraine, subsequently beginning Elise's investigation at the Lambert Residence.

Trivia

 * The demon is often commented through bearing a strong resemblance to the Sith apprentice Darth Maul from the science-fiction series "Star Wars." This is most likely due to the red markings on both their faces and their blackened skin, as well as their sinister personalities.
 * The demon makes a crackling sound whenever it is going to be seen, making his appearance very obvious. This explains why many fans suspect that it was the demon behind Allison at the end of Insidious: Chapter 2.
 * In the demon's spare time he enjoys his favorite hobbies: puppeteering and sharpening his claws.
 * The demon made an appearance in Insidious: Chapter 3. His presence made a dog bark at the shadows as he showed his face behind Elise, symbolizing that he was soon going to begin haunting the Lambert family.
 * The demon is assumed to be the strongest entity/antagonist to have ever appeared in the series, mainly because he is a demon, not a spirit, which cuts off any bond he has with the physical plane and makes him indestructible.
 * The demon plays the song "Tiptoe Through the Tulips" in his lair, which is the same song that the spirit of The Dancing Boy played in front of Renai. This implies that the demon sent him to haunt Renai, which could mean that the demon has control over other inhabitants of the Further.
 * The demon could be the Insidious version of Satan as it shares many similarities with the Devil in appearance, personality, and abilities. Like Satan, it has power over the dark realm of the afterlife and its inhabitants in the Insidious universe.
