Kevin Wendell Crumb

"The impure are the untouched! The unburned! The unslain! Those who have not been torn have no value in themselves, and no place in this world! They are asleep!"

- The Beast explaining his own motives.

"You like to make fun of us, but we are more powerful than you think."

- Dennis "We trust in him. He'll protect us. Look at what he can do. Let him show the world how powerful we can be."

- Patricia to the others, contemplating the power of the Beast.

Kevin Wendell Crumb is a recurring character of the Eastrail 177 film series, He is a mysterious man who suffers from an extreme case of Dissociative Identity Disorder (DID), and has 23 separate personalities residing in his mind. Kevin and the majority of his personalities are by no means evil, however two of the most dominant—Dennis, an obsessive, cold and tough man, and Patricia, a manipulative female—are both aggressive and vicious in their own way. Dennis and Patricia are also devout believers in a burgeoning 24th personality — "The Beast" — whom they believe will avenge them against the "Impure". The Beast serves as the main antagonist of the 2016 film Split, and the secondary antagonist of the 2019 film Glass.

He was portrayed by James McAvoy, who also played Wesley Gibson in Wanted, Bruce Robertson in Fifth, and David Percival in Atomic Blonde.

Past
When Kevin was a child, his father, Clarence Wendell Crumb, left on a train and never came back. Kevin's father died in the same train crash (orchestrated by the villain Elijah Price, known by his unforgettable moniker "Mr. Glass") that left David Dunn, the protagonist of Unbreakable, as the sole surviving passenger. This left three-year-old Kevin at the mercy of his abusive mother, who would severely punish him if he did not keep everything clean and in order. To avoid his mother's abuse, Kevin began to develop multiple personalities as a defense mechanism. Dennis, the protector alter with obsessive-compulsive cleaning habits, was a direct result of his trauma.

Kevin ultimately developed 23 individual personalities, each of which are able to take control. If the fan theory involving Mr. Glass is true, then Glass not only created a superhero, David Dunn, but also inadvertently made Kevin a supervillain as well.

Kevin, presumably Dennis, worked at the Philadelphia Zoo when something jarring happened: two girls approached him and played a cruel, childish prank on him. Without warning, both girls took his hands and forced him to touch their breasts, before they ran away laughing. This left Kevin disoriented and in shambles, and possibly contributed to Dennis's peculiar sexual appetite.

Dennis and Patricia
As of September 18, 2014, the personalities seemed to have buried Kevin away deep in his mind. At the beginning of the film, Dennis (a stern man who suffers from OCD) kidnaps Casey, Claire and Marcia, knocking out Claire's father in order to abduct the three girls. He keeps them in a room in his home where the three girls are later introduced to Patricia (a matronly Englishwoman), another one of Kevin's alters. This bewilders and invokes fear within the girls. When Hedwig (a 9-year-old boy with a lisp) "takes the light" (control of Kevin's body), Casey tries to befriend him in hopes of escaping. Throughout the film, mainly through the discussions between Kevin's alters and his therapist, Dr. Fletcher, it is established that the presumed dominant personality is Barry (an effeminate male fashion designer) who tries to subjugate the others and keep them from staying in the light. However, two of the other personalities (Patricia, a religious nut, and Dennis, who also has ephebophilic fantasies) have suppressed Barry with the help of Hedwig, who is able to take the light at his will.

When Claire tries to escape the room through the drywall ceiling, Dennis finds her and then locks her in a separate room on her own. He tells her it isn't nice to trick children because it shows who someone really is. Soon after, when Patricia prepares food for Casey and Marcia, she forbids them from having Claire join them. When Marcia attacks Patricia and tries to make a run for it, Patricia finds her and threatens her with a knife. Like Claire, Marcia is put into a separate dingy room next to Claire's room.

Casey befriends Hedwig, and tries to influence him. Hedwig excitedly warns the girls about 'the Beast', a malevolent 24th personality with incredible abilities. He also reveals to Casey that there is a window in his room, which she perceives it as a potential escape route. However, when he shows her the 'window', it is shown to be a hand-drawn picture of a window.

She grabs a functional walkie-talkie nearby and radios for help, but the person on the other end thinks that it is a prank and dismisses her; Patricia then subdues Casey. Barry sends several email messages for help to Dr. Fletcher, revealed to be Barry feeling threatened by the bid for control by Dennis and Patricia. When Dr. Fletcher approaches and tries to reason with Kevin, she realises that he has kidnapped the girls and tries to convince him that what he is doing is wrong. Dennis sprays her with chloroform and carries her into the living room. Enacting a sort of ritual, Dennis then buys flowers and Patricia visits a train car (presumably the same train Kevin's father left him at.) Dennis then becomes 'the Beast', exhibiting physical changes such as increased muscle mass and several inches added to his already tall height. The Beast snarls, his persona dissolving into an animalistic mentality before launching himself on a rampage. When she recovers, Dr. Fletcher writes down Kevin's full name, knowing that the resulting awakening of his original personality will be enough to subdue him. The girls, in the meantime, try to escape from their confinements.

“The Beast” attacks


"The broken are the more evolved."

- The Beast

Returning to his hideout, “The Beast” confronts Dr. Fletcher. Before she is able to speak Kevin's full name, a tactic which would call Kevin to the light and throw the Horde into chaos, he crushes her to death against him. He then proceeds to rip apart and eat both Marcia and Claire. Meanwhile, Casey stumbles upon Dr. Fletcher's corpse, as well as an instructional note the doctor the left behind on how to defeat the Beast. When the Beast closes in on her, demonstrating the ability to climb up walls, Casey uses Kevin's real name to call him to the light. The Beast is briefly tamed, and the actual Kevin (who has been restrained for years by the other personalities, and has no memory of what he has done between then and now) emerges. Horrified by the death of Dr. Fletcher, he orders Casey to kill him with a shotgun he bought before the Beast can return—however, the Beast returns when Kevin's other personalities desperately try to defend themselves. As the Beast reawakens, it pursues Casey into the basement of its lair, eventually cornering her in a cell. Casey shoots him twice at point blank range with Kevin's shotgun, but it proves to be ineffective, as the shells fail to do more than pierce his skin.

Reaching the cell, the Beast voices his maniacal plans to rid the world of the 'untouched' (As in, the people who he feels have never suffered pain or discomfort, unlike him). The Beast bends the bars with its bare hands to gain entry, but before finishing, it notices the scars on her body from her previous abuse at the hands of her uncle. Realizing that he has met a kindred spirit, one who has also suffered exceptional abuse at the hands of a trusted relative, he declares her to be "pure," and leaves a bewildered Casey in peace. Casey is eventually discovered and rescued by Kevin's co-workers at the Philadelphia Zoo. Recovering from the battle, Patricia, Dennis and Hedwig speculate in awe at the power of the Beast, marvelling at what it was shown to be capable of doing. Kevin voices his plans to change the world, and awaits the next feeding of 'the Beast' now under the man's newest and diabolical collective nom de guerre "The Horde".

At the end of the film, in a restaurant, the people are watching the news about The Horde, one of the waitress talks about the similarity with a case 15 years ago where a man in a wheelchair was arrested and had a nickname too which she can't recall. A man named David Dunn sitting next to her tells her his name was Mr. Glass.

Glass
Kevin returns taking a group of cheerleaders hostage until the intervention of a superhero called the Overseer (later revealed to be David). However, both David and Kevin end up being arrested by the authorities and sent to an insane asylum where Elijah is also being held in.

The three are being held by Dr. Ellie Staple, who tries to persuade them that there is no such thing as superhuman powers and that they actually have mental illness. To ensure of Kevin's compliance, Staple has built a system of flashing lights that activate with Kevin's closeness, which opens up one personality to another.

Eventually, it turns out that Staple is part of an anti-superhuman society that is willing to refute any evidence regarding to supers and that she plans to kill Eiljah, David and Kevin to accomplish it. Being aware of Staple's intentions, Elijah forms an alliance with Kevin, who allows the former to escape while battling a freed Kevin in the institution's grounds. However, Kevin soon learns from David's son Joseph that Elijah is the one responsible for his father's death in the same train crash, resulting an angry Kevin to kill Eljiah by crushing his ribs while Staple sends over several armed men to kill David by drowning him in a pothole.

Eventually, Kevin meets his death when Casey Cooke (one of his former hostages) puts him back into the light, which subsequently erased all his separate personalities and allowed Staple's men to shoot him down. Despite Kevin's death, his actions were enough to let Elijah record the event with the security cameras before he died. Elijah's mother, Joseph and Casey would later expose the footage to the public in revenge for the deaths of Elijah, David and Kevin, thus exposing the existence of those with superhuman abilities and leaving Staple's plan in complete vain.

Personality
"He's done awful things to people, and he'll do awful things to you."

- Hedwig describes the Beast. Kevin is an extremely impenetrable and complex individual: The mental disorder that he prominently suffers from causes him to have a myriad of personalities, though only a few of them are shown in the film:

There are sixteen other personalities that are not shown, but the names of which are seen on
 * Kevin himself: A terrified young man who, from what can be seen at the end of the film, has a conscience and expresses deep shock and horror at what his other identities have done. He is so horrified by what he has done that after realising the destruction he has caused and the trauma he inflicted on Casey, he encourages her to kill him, and the only thing that prevents this from happening is the frantic interference of the other personalities that existed in his head. He spends the majority of the film restrained by these personalities.
 * Hedwig: A 9-year-old boy with several compulsive behaviors, such as proclaiming that he has red socks, crawling on bent knees, and ending sentences with 'et cetera'. He loves to dance crazily, do drawings and he is disciplined by the other personalities. He befriends Casey, and even develops some romantic feelings for her. He appears to have the unique ability of taking the light when he pleases. Hedwig is rather gullible as a result of his innocence and naivete, easily baited by Casey at one point and cowed by some of the other personalities, very few of whom truly respect him (not even Barry, who simply calls him 'the boy'). He is awed by the power of the Beast because of his childish nature. He has a fear and subservience to the other personalities, especially Patricia (whom he calls 'Miss Patricia'). Apparently, he is not as partial to their schemes as he wants to be, stating that "they don't tell me things", and that they make fun of him. When the Horde is destabilised after Casey uses Kevin's full name, Kevin willingly surrenders the light to Patricia; this is one of the many hints that Hedwig holds special subservience for Patricia.
 * Barry: The originally dominant personality in Kevin's head - calm, tranquil, and levelheaded to some extent and working to control the other personalities, Barry is the personality that is used to communicate with Dr. Fletcher, but he is exploited by Dennis in the latter's bid for control over Kevin's head. He is a charismatic, persuasive, and somewhat effeminate male with an incredible talent for fashion and design. It is implied that he is a very commanding and authoritative individual (described at one point as an extroverted leader). When Barry steals the light for real and tries to talk to Casey he shows genuine concern for her well being, assuring her that the group of personalities in Kevin's head are going to work through this. It is hinted that he believes (quite justifiably) that Dennis and Patricia are very unstable.
 * Dennis: One of the more disturbing personalities, Dennis is cold, temperamental, and manipulative, with a perverted liking for watching young girls dance naked. When he captures the three girls, he tries to get them to dance for him. The only way this is thwarted is when one of them urinates on him, to which he reacts with inarticulate fury. He demonstrates traits of obsessive-compulsive disorder and a firm, sometimes violent, tendency towards cleanliness and order (which is possibly duplicated from Kevin's abusive mother). He admits to Dr. Fletcher that he thinks Kevin himself to be weak, and that the other personalities don't respect him, much to Dennis' dismay. Dennis acknowledges that the Horde isn't perfect but doesn't believe they deserve ridicule. He shows himself capable of talking on pleasant terms with Dr. Fletcher despite his reputation, but he has an explosive temper. He explains that his altar came about because of the malevolent ways Kevin's mother punished him, and that the only way to sate her was through keeping everything tidy and in order. Dennis is devious and exploitative, being shown to have been masquerading as Barry since the very beginning of the film. However, Dennis' efforts to conceal himself aren't perfect, since he overextends himself in trying to convince Dr. Fletcher that he is Barry and is unable to ultimately conceal his OCD.
 * Patricia: A sophisticated, obsequious, orderly, and polite "woman" who has considerable command over some of the other personalities (This personality claims that the others 'listen' to her). Patricia is very disciplined and intellectual towards the other personalities, and towards other people, and is also very calm - she assures Casey, Claire and Marcia that Dennis will not touch them because they are to serve a greater purpose than Dennis's desires. She has considerable manners, making sandwiches for the girls and being generally pleasant to them, even exchanging 'fun facts' about animals while doing so. Patricia is revealed to be surprisingly destructive and dangerous in her own right, as evidenced by her calm (but extremely threatening) way of dealing with Marcia by soothing her verbally whilst holding a knife to her stomach. Patricia is a perfectionist, reacting angrily when she cuts a sandwich in awkward halves before doing so again. Patricia, despite being an authority unto herself, worships the Beast the most out of the other personalities: stated to be one of the 'undesirable identities' because of her fervent belief in the Beast's existence, and later on she waxes lyrical about the greatness of the Beast and being the personality who finally gives the light to the 24th identity. Later on, she marvels about what the Beast accomplished, and declared that they let the Beast show how powerful the Horde could be.
 * The Beast: By far the most dangerous, hostile and terrifying of all the personalities, the Beast is the 24th identity that resides in Kevin's mind. Apparently the Beast resided in the train yard where Kevin's father died, and up until his arrisal he was not seen by the other personalities. The Beast is a malevolent and rancorous figure, idolized by Dennis, Patricia and Hedwig, who all await his arrival. He is a megalomaniac, believing that those who are broken and who have suffered are superior to anybody else, but also that those who haven't are irrelevant, and that they are 'asleep'; this philosophy rules its actions entirely, since the Beast goes from savagery to glee at seeing that Casey has suffered seriously in her life and declares that her heart is 'pure'. The Beast is extremely destructive and violent to the point of savagery, having an unquenchable lust for human flesh, and an intense perspective that the rest of the world are impure because they have not suffered like he has. The Beast possesses superhuman strength, speed, agility, stamina, invulnerability and pain tolerance - it can rip metal bars apart and snap a human body in half with its bare hands. It also has the ability to climb walls by latching on to the slightest imperfections in a surface. Finally, the Beast is incredibly hard to kill, since bullets are virtually ineffective against it and knives shatter against its skin. The Beast is viewed as an almost Godlike figure by the other 23 identities, and they are in awe of what it can accomplish.
 * Jade: She appeared on a video log and briefly appeared after Casey called Kevin "into the light". Jade seems to act like a typical teenage girl with a foul mouth. She apparently has diabetes and needs to take insulin shots for it. She seems to be the only one, that believes that the Alters are different people rather than personalities. Considering in her video log, she frustratingly makes mention that she's the only one who has to take the insulin shots while the others are perfectly healthy physically.
 * Orwell: He appears briefly when Casey calls Kevin "into the light". Orwell is a highly intelligent and introverted man whose verbosity tends to overshadow his intended meaning. He can't help but compare his and the Alter's prediciments to a certain point of history, as seen when he tries to desperately explain to Casey that The Horde doesn't represent the rest of them. He is shown to have been concerned about the Horde's advances for some time before the incident.
 * Mr. Pritchard: He appears briefly while in custody. He is a Professor of Cinema, specifically Japanese cinema ranging between the 1950s-80s. He expresses fervent frustration at being imprisoned, despite being in favour of Kevin being in the light. He has a wide vocabulary, but is not nearly as verbose or extraneous as Orwell.

Kevin's computer also listed other personalities that haven't been shown yet:
 * Heinrich
 * Norma
 * Goddard
 * Bernice
 * Polly
 * Luke
 * Rakel
 * Felicia
 * Ansel
 * Jelin
 * Kat
 * B.T
 * Samuel
 * Mary Reynolds
 * Ian
 * Mr. Pritchard

Trivia

 * Kevin's background and the will of his personalities to become a superior being by creating another monstruous and superhuman personality through sacrificial ritual makes him quite similar to Francis Dolarhyde.
 * Considering that Split exists in the exact same world as M. Night Shyamalan's Unbreakable (which is essentially an origin story for a superhero), Split can be considered to be Kevin's origin story as a supervillain. This is lamented by Price near the end of Glass.
 * Each of the three protagonists of the Unbreakable Trilogy (David Dunn, Elijah Price, and Kevin W. Crumb) have their own distinctive colors, David's colors are dark shades of green, Elijah's colors are shades of purple and Kevin's colors are shades of yellow.
 * Another fan theory especulates that in Unbreakable when David is exploring his extrasensory perception power that helps him see if people have committed crimes when making contact with them, he bumps into a woman wearing a pink coat grabbing a kid by the hand, it is implied that the woman abuses the child, which leads to fans to especulate she was Kevin's mother and the kid was Kevin.
