Lewis Pepper

Lewis Pepper is one of the main characters from the Mystery Skulls Animated web series.

A ghost with fire-based powers who antagonizes Vivi, Arthur, and Mystery. He's revealed midway through "Ghost" to have been a former member of the Mystery Skulls and been dating Vivi but he was killed by a possessed Arthur and now seeks revenge.

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

Pre-death
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
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 with purple outlines resembling a bow tie, a white dress shirt with a magenta pink tie, black trousers and black dress shoes.

Personality
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.

Abilities

 * Constructs 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.
 * Memory Erasure: Lewis appears to have the ability to erase the memories of others. However, it is unknown how far this ability goes, due to the only time we see him using this ability is when he is erasing Vivi's memories of him in "Ghost."
 * 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.
 * Space Manipulation: In "Hellbent," it is shown that Lewis has created 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. Unless this was some sort of illusion, this would imply that Lewis has the ability to shape the laws of space to his will to a certain extent.
 * 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.
 * True Form: Lewis has the ability to 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).

Trivia

 * According to Mystery Ben's Blog, Lewis' design is inspired by several different sources. 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.
 * Lewis' 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' blood type was O. In blood type personality theory, people with blood type O are thought to be confident, self-determind, 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.
