Lewis Pepper is the skeletal ghost resident of The Mansion and a former member of the Mystery Skulls.


Lewis has a muscular body, broad shoulders, and is very tall. He also has bangs, which resemble an exaggerated pompadour.

Pre-death (alive)

Lewis had purple hair, a square face, tan skin, and a hook nose. Lewis wore a purple vest, a white dress shirt with a magenta ascot, dark purple jeans, and purple sneakers.

Post-death (current)

Lewis has magenta, flaming hair, a jaw-less skull that levitates in place, 3 ribs that stick out on both sides of his chest, hands resembling gloves from the electronic music duo Daft Punk. Lewis wears a black suit, the lapel resembling bat wings, a white dress shirt with a magenta pink tie, black trousers, and black dress shoes.


Lewis was described as a kind person in life and was in love with Vivi in an active relationship. However, after a possessed Arthur killed Lewis, he's now a vengeful and enraged ghost. He seems to be unaware that Arthur was possessed and most likely assumes Arthur did the deed out of malicious intent, hence his extreme hatred towards Arthur. Lewis will stop at nothing to get revenge on his murderer.

However, Lewis still seems to be capable of human emotion. He clearly still harbors tender feelings towards Vivi, even in death, and he seems regretful after dropping Arthur to his supposed death in "Hellbent," even though he believes Arthur killed him intentionally.


Lewis was formerly a member of the Mystery Skulls Paranormal Investigation team. On one fateful journey, the team entered an ominous-looking cave. Upon splitting up, Vivi went one way, while Lewis, Arthur, and Mystery went another. However, Lewis only found an empty pit filled with stalagmites, the bottom of which Vivi's path led her to. As he tried to turn back, Arthur became possessed by a malicious spirit and pushed him off the cliff edge, leading to his death.


Months later, the team's van breaks down near a large mansion. (The purple lightning coursing through the dashboard as this happens indicates that it's Lewis' handiwork.) Once inside, the team is 'Greeted' by Dead Beats, Attacked by a possessed suit of armor, and Frightened by the Living Portraits, one of which triggers a trapdoor. While Vivi and Mystery somehow land in the kitchen, Arthur finds himself in a deep pit with a coffin and several unlit torches. The coffin opens to reveal Lewis in his ghost form, with a golden beating heart-shaped object over the left side of his chest. He points to Arthur ominously in sync with the lyric "It's you I hate the most", showing his grudge against him, then forms his spectral pompadour and begins chasing after him.

Just as Lewis has Arthur cornered, Vivi jumps in between the two. Lewis stops short, remembering his feelings for Vivi, though she appears not to recognize him, and tries to give her his heart. However, Arthur pulls her away at the last minute. They reach for each other, though in vain, and the heart falls to the ground, breaking and turning from its golden glow to an icy blue. Lewis explodes in a rage, but they escape the fireball, leaving him alone with his literal broken heart.

As the van drives off, Lewis opens the "heart" (revealed to be a locket) to reveal a photo of him and Vivi together. Resuming back to his human form, Lewis sheds a single tear and disappears. As the van drives off into the night, the mansion vanishes along with him.

Freaking Out

Sometime later, Shiromori's search for Mystery leads her to the former location of The Mansion. While she manages to find Mystery's essence and grows a flower tied to his being, she reawakens Lewis' dormant spirit in the process, who attacks her. Shiromori survives his assault and prepares for a confrontation, but ultimately seems to decide that tracking down Mystery is more important and escapes underground.

Lewis notices the discarded flowers Shiromori grew using Arthur and Vivi's essence. He lovingly picks Vivi's flower up and wrathfully crushes Arthur's underfoot, showing that his desire for vengeance has not weakened during his inactivity. He then uses a few petals from Vivi's flower to revitalize his shattered heart locket, then absorbs a table with a coffee cup on it and sets off, accompanied by a few Dead Beats. As he crosses the road, a truck runs him over, but Lewis uses the occasion to possess the entire truck, reshaping it in his image, as the terrified driver, Rooster, barely escapes with his life, before slamming the gas pedal.


Lewis attempts to break down the van, glitching out the radio and causing it to play Hellbent as he chases them in his possessed truck. When Shiromori attacks Mystery he inadvertently knocks her off the van and runs her over, then follows the van down the hill to Lance's mechanic workshop. He confronts Arthur and recalls his past life, his relationship with Vivi, and Arthur's jealousy over it that led to his death. He tosses Arthur into the back of his truck, which becomes a recreation of the Cavern he was killed in. His Dead Beats lead Arthur to the cliff he fell from originally, and Lewis corners him and dangles him over the edge. As he's about to drop him, though, his skull changes into his living appearance and Arthur recognizes him right before he's dropped. Either the shock or regret of killing Arthur breaks Lewis' heart again, even more so than when it cracked in "Ghost," and he has a fearful/regretful expression as the video ends.

The Future

As Lewis heard Arthur's voice, he looked at him in remorse as he saw himself in Arthur's place, falling towards his death. Lewis then tried to reach out for him, but Lance shot him through the chest, causing his heart locket to fall to the floor as the illusion broke and the stalagmites turned into boxes. Lewis then turned around in anger as Lance shot at him frantically, with none of his attacks managing to land a hit, save for the chest area where Lewis's heart would normally be, causing him to look at Lance in rage before presumably knocking him unconscious soon after.

Recovering from his fall, Arthur noticed Lewis's heart locket on the floor and grabbed it, immediately alerting Lewis to his presence as he looked at him in alarm. Looking inside, Arthur saw a picture of Lewis and Vivi. As he looked even closer, the picture changed to that of himself with Lewis, Vivi, and Mystery. Lewis then snatched the heart away from Arthur and turned his back towards him, feeling flustered over what Arthur had seen. Looking into the locket himself, he was then surprised to see that the picture had changed and that Arthur and Mystery were now a part of the picture as well. Seeing this, inky black tears began to form in his sockets before he dropped to his knees as Arthur looked at him, seeming taken aback.

After an explosion caused by Shiromori crashing into the truck, Lewis and Arthur somehow managed to emerge unscathed with Arthur's uncle in tow as they came out and saw Shiromori's giant vines creeping towards them. Lewis then began to burn the vines with his pyrokinesis as Arthur ran off with his uncle to safety. When Mystery began transforming into Murder Mystery, Lewis clenched his head (either from the sudden noise or in pain) before opening his eyes and seeing Vivi in pain as he quickly rushed to her side to make sure that she was okay. Arthur soon joined the group as well as before all of them looked up in shock to see the horrifying beast, Murder Mystery towering above them.

Vivi then utters "What the fu-" before abruptly being cut off by Arthur screaming in terror, causing Lewis and Vivi to glance at him.



Lewis and Vivi were part of the same paranormal investigator group while he was alive. Lewis is in love with Vivi and is literally hellbent on reuniting with her and getting revenge on Arthur. He still seems to deeply care about Vivi even after death as he keeps a picture of the two of them in his locket at all times as shown in each video.


Before his death, Arthur and Lewis were both members of the Mystery Skulls but after he was killed by a possessed Arthur, he now seeks revenge on him. Lewis is most likely unaware that Arthur was possessed—who doesn't seem to remember that Lewis was murdered—and that he was looking for him all the time since Lewis's death.

In fact, at the end of Hellbent, when Lewis finally exacts his revenge on Arthur and throws him off the cliff, his heart turns gray and cracks even more severely than it did in Ghost, and his expression shows regret over his action. This might imply that Lewis, despite his hate towards Arthur, still deeply cares for him and might have had a feeling that Arthur was actually innocent. This is confirmed in The Future.


There is not much known about Lewis' and Mystery's relationship. Before his death, they were members of the same team and seemed to be friends.

Mr. & Mrs. Pepper

Mr. and Mrs. Pepper are Lewis's foster parents. One night, a young Lewis showed up on their doorstep, scuffed up and half-unconscious as a child. Despite numerous attempts to discover where he came from and what brought him there, Mr. & Mrs. Pepper were never able to unravel his past. With nowhere to go, they decided to take him in as one of the family.[1]

Lewis' sisters

Lewis has three younger sisters, however, unlike Lewis, they appear to be biologically related to Mr. and Mrs. Pepper rather than being adopted. In the following picture, the one on Lewis' shoulder is Paprika, the one in the front is Belle, and the one under the table is Cayenne.[2] Before his death, Lewis used to babysit his sisters.


  • Construct creation: Although it is not known for certain yet whether the mansion was made by Lewis or was simply taken over, he is shown directly to have this ability when he constructed street lamps when confronting Shiromori, and made a table and a chair before setting off to find Vivi and Arthur. The Dead Beats also seem to be of Lewis' creation as well.
  • Levitation: Lewis shows that he can hover in the air at will.
  • Pyrokinesis: Lewis has the ability to produce and control fire, though it is unknown if his ability to manipulate fire also applies to already existing fire or only to his own. Flames produced by Lewis are an unnatural purple color. He can apparently shape his fire into objects, such as his hair, which are created using the fire emanating from his skull.
    • Explosion: Lewis can generate a massive fiery explosion using his pyrokinetic powers, as shown when he is enraged at the end of "Ghost" and his flaming hair flares into a detonation that engulfs the entire mansion.
    • Fire punch: Lewis can coat his fist in flames when punching a foe.
    • Fireball: In "Hellbent," Lewis throws a fireball at the Mystery Van that instantly pops one of its tires.
  • Dormant Form: Lewis has the ability to retreat into his heart locket, allowing him to recover.
  • Super strength: In "Freaking Out," It is shown Lewis has this ability. When Shiromori accidentally revived Lewis' spirit, Lewis punched her head and one of her arms off with a fist covered in fire.
  • Object possession: As shown in "Freaking Out," Lewis is able to possess objects and change its general appearance to make it more suitable to himself. The object possessed also acquires ghostly properties similar to his, as shown when he gets his possessed truck through a tunnel too small for it by transforming it into a torrent of flames. It is also possible he used this ability to take over the mansion, and it is supported by the mansion grounds still being there when it vanishes, but if this were the case it is unknown why the mansion disappears entirely rather than simply returning to its pre-possessed state.
  • Mechanical shutdown: His flames appear to affect technology of his choosing, in "Ghost," his flames can be seen as the reason for the van to stop working, forcing the crew to stop by the mansion, and in "Hellbent," once Arthur punches the car's panel, his prosthetic stops working.
  • Illusions: Lewis has the ability to change the appearances of objects such as himself or those he possesses. He can change his look between his skeletal form (which he seems to use most of the time) and his appearance back when he was alive (typically only revealed in rare, special circumstances). In "Hellbent," it is shown that Lewis can create a replica of the cave where he died in the wagon of the truck he was possessing, despite the truck seeming too small on the outside to contain it. It was revealed in the next video this was nothing more than an illusion.
  • Nigh invulnerability: As a ghost, Lewis seems to be almost entirely immune to physical harm. However, attacks that hit the location where his heart would have been can stagger him.
  • Driving: Remarkably drives a van, and a truck without training.


  • Heart Locket: Lewis's heart houses his spirit, powers, and memories while acting as his tether. Lewis was able to feel pain from the heart being shot by Lance's gun, and in the area of the chest where the heart should be, implying the heart's placement is integral to Lewis's form. Damage to the heart locket has a negative effect on Lewis's mental state, ranging from unbridled fury (as seen in "Ghost" and "Freaking Out") to pain and despair (as seen in "The Future").


Lewis' Profile on Mystery Ben's blog.

  • According to Mystery Ben's Blog, Lewis' design is inspired by several different sources.[3] His skull's design is based on a number of different things including Skeletor's skull and Yoko Littner's hairpin. His body is based on Fred Jones and Grunkle Stan, and his gloves are based on the ones worn by the electronic music duo Daft Punk.
  • Lewis is named after Luis Dubuc from Mystery Skulls.[4]
  • Lewis's tragic backstory and resurrection parallels several supernatural anti-heroes, most notably Spawn by Todd McFarlane.
    • Both characters deeply loved someone while they were alive. After being unjustly murdered, however, they returned to life as undead versions of their former selves with an array of supernatural powers and a desire for vengeance.
    • Unlike Spawn, however, it is unknown if Lewis acquired his powers on his own or through a pact with a demon.
  • His ability to possess vehicles resembles Ghost Rider from Marvel Comics.
  • Lewis' main color is pinkurple.[5]
  • Lewis' blood type was O. In blood type personality theory, people with blood type O are thought to be confident, self-determined, ambitious, strong-willed, intuitive, agreeable, competitive, and athletic; but also unpredictable, spiteful, self-centered, cold, aggressive, arrogant, envious and ruthless.
  • Lewis' flower that appears in "Freaking Out" is a rose. Roses often represent passion, intrigue, and sensuality. His flower has the color of his heart in the middle.
  • His instruments are vocals and violin.
  • Lewis's height is 7 feet and 3 inches.
  • His favorite food was "The Chocolate Covered Bhut Jolokia Special". Coincidentally, the Bhut Jolokia Pepper is more commonly known as the Ghost Pepper.
  • In "Ghost", Mystery Skulls' amnesia of Lewis is implied to be connected to Lewis's ghostly state. This suggests Lewis might have the ability to erase the memories of others, although it is unknown how far this ability goes, due to Arthur and Vivi having different memories of Lewis.
  • A tweet on Mystery Ben's blog on the 27th October 2020 wished Lewis a happy birthday. Whether this is his actual birthday is yet to be confirmed. If he was born on the 27th October, this would make him a Scorpio.
