Oogie Boogie is the sinister, abusive, and voraciously power hungry Boogie Man, resembling a large burlap sack shaped like a starfish. Inside of him are thousands of bugs (along with 2 spiders and a snake). His life revolves around gambling, and loves gambling with others' lives. He likes to torture people. He is also apparently the "Shadow on the Moon at Night" as the shadow shown on the moon was an exact replica of him. He also used to be the king of his own holiday, "Bug Day", which eventually fell out of favor, resulting in him moving to Halloween Town. He also fears Jack Skellington, as evidenced by their final confrontation when meeting face to face. This fear was a result of their first meeting, when Jack Skellington destroyed his bug minions after he attempted to transform Halloween Town into the new Bug Day.
Ironically, Oogie has no skills for gambling; on three occasions he rolls snake eyes, and admits he has to resort to cheating - he slams his fist upon the table to shake the dice, resulting in eleven. He is also somewhat lecherous, as which is evident when he's easily distracted by Sally's bare (and dismembered) leg. According to Lock, Shock, and Barrel, as well as some of his deleted song material (which is included in the soundtrack version), he is also very good at making a concoction known as Snake and Spider Stew, though it would seem he tends to use people as ingredients. He is a sadist who has his henchmen abduct people and bring them to his lair for him to torture and eventually kill and/or add to his Snake and Spider Stew.
Oogie's outside appearance is very simple. He is covered from head to toe in a grey burlap sack, and an obvious seam is visible along the sides. Oogie is quite rotund, with stumpy legs and fingerless arms, a stark contrast to Jack Skellington's gaunt, tall physique. Like Jack, the "eyes" in Oogie's head are featureless black holes, as is the inside of his mouth. The tip of his head extends outward and flops down, vaguely resembling Jack's Santa hat. On the inside of the sack, Oogie is a huge mass of a variety of different colored bugs. In the movie, Oogie also produces a snake from his mouth as a "tongue" to intimidate Santa Claus by hissing at him. The majority of Oogie's consciousness is held by one, green, earwig-like bug in his head, and it is only by squashing this one that Oogie can be killed.
When Jack orders Lock, Shock, and Barrel to keep Oogie Boogie out of his plans to bring Santa to Halloween Town, they disobey him and bring him to Oogie, who chains him up for torture while he sings his song. While Jack makes his Christmas run, Sally tries to stage a rescue attempt, but is caught by Oogie. When Jack realizes how much he messed up Christmas and how much Halloween needs him, he sets off for Oogie's Lair to free Santa and Sally, who are nearly dumped into a fiery molten pit. Jack battles the traps and torture devices of Oogie's Roulette Wheel as Oogie tries to escape. Jack manages to pull on one of his loose threads. This shreds out Oogie's colthing revealing, him to be a colony of bugs wrapped in sacking. When Jack pulls the loose thread, it causes the whole sack to fall off, and causes the bugs to fall into a fiery molten pit, with one of them is crushed by Santa Claus.
In The Nightmare Before Christmas: The Pumpkin King, Oogie's origins and the birth of his rivalry with Jack were revealed. As it turns out, he once had his own holiday, Bug Day, that was (most likely) forgotten by the people of the real world and thus vanished. Unfortunately, Oogie escaped, found Halloween Town and decided that it would be the new Bug Day. He and his army of insects invaded the town and nearly took it over. Jack found out and he defeated the bugs and Oogie. Oogie survived the battle, learned to fear the Pumpkin King, and was banished to his underground lair.
In the 2005 video game The Nightmare Before Christmas: Oogie's Revenge, Oogie was resurrected by his henchmen Lock, Shock, and Barrel, who sewed him together after Jack left town searching for new ideas for Halloween. He immediately began planning to seize power and vengeance, beginning with Dr. Finkelstein, who Jack left in charge in his absence. Oogie replaced Finkelstein's brain with one of his own creation that bent the Doctor to his will, and quickly deceived the residents of Halloween Town and tricked the townspeople into making traps for Jack, stating that Jack wouldn't return if they couldn't make an even scarier Halloween for next year. Oogie's plan was to become the Seven Holidays King, by usurping Jack's position as the leader of Halloween Town and kidnapping the Holiday Leaders for the other holidays: Valentine's Day, St. Patrick's Day, Thanksgiving, Independence Day, and Easter. The remaining holiday was Christmas, which he planned to secure himself due to a personal vendetta against Santa. With help from Lock, Shock, and Barrel, Oogie successfully kidnapped the real leaders and imprisoned them in the Oogie Corridor, a series of treacherous subterranean caverns teeming with lava and booby traps. He then had the trio hide each Holiday Door in a different area of the town so that they wouldn't be discovered, and the leaders could not return home. By December 23rd, his plan is nearing fruition, the entire town has been booby-trapped and the citizens are afraid to set foot on the streets.
Jack returns to town in the afternoon on Christmas Eve, shortly before Oogie broadcasts a message saying that he is now the ruler of Halloween Town, which he renames Oogie Town. Jack battles a few skeletons, and after learning the situation from the Three Mr. Hydes, confronts Oogie's shadow in Town Hall. Oogie loses, but puts it down to beginner's luck, and retreats while promising that they'll meet again, with Jack collecting the Halloween Holiday Door as a result. He occasionally comes on the loud speaker and broadcasts messages while Jack goes to work undoing the damage he caused, defeating the monsters and claiming the Holiday Doors in each area: the Valentine's Day Door from the Graveyard, the St. Patrick's Day Door from the Doctor's Lab, the Thanksgiving Door from the Pumpkin Patch, and the Independence Day Door from the Residential Area, despite Lock, Shock, and Barrel's best efforts to deter his progress. After defeating the trio on the Mayor's roof, they open a void that sends him to the Oogie Corridor. While navigating the maze of caverns, Jack finds the imprisoned Holiday Leaders and an elevator that leads to the Town Square. He finds Oogie at the end of the maze, in a casino-esque setting, and battles him. Upon his defeat, Oogie reveals that Jack had only defeated his shadow, and that the real him was already in Christmas Town. Jack collects the Easter Holiday Door after defeating him, leaving the Christmas door as the only one out of his possession, and returns to the plaza via a sewage line beneath the casino. After instructing the Mayor to free the other Holiday Leaders, Jack heads to the Hinterlands to restore the Holiday Doors and follow Oogie. Partway through this process, he confronts Oogie's two strongest monsters, the Fire King and the Ice King, and claims the Christmas Door from them. After restoring the seven trees, he heads to Christmas Town, where he finds that Oogie has already wreaked havoc. After fixing it, he heads to another part of the town, where the real Oogie is standing in Santa's sleigh and watching a rig that he has created to murder Santa Claus. Once again, Jack foils his plans, and Sally brings the coffin sleigh and skeleton reindeer so that Santa can still deliver the presents on time. Oogie flies away on the sleigh, but falls out of it thanks to a Halloween present that Jack had an elf slip into the bag, landing in the seven holidays' junkyard. Infuriated, he calls all of the nearby bugs to him, and with the materials in the junkyard, he becomes Mega-Oogie, a ten story version of himself. Jack confronts him in the junkyard, and with an effort, defeats him at last. Oogie is forced to watch as his bugs spill out of his body, leaving nothing more than a giant, empty patchwork sack as he once again meets his end at the hands of the Pumpkin King.
Oogie Boogie is one of the allies that Pete recruited for Maleficent. He is usually seen annoying the rest of his allies in meetings, but cares about their common goal of total world domination. Soon after Jafar and Ursula are defeated by Sora, Oogie has been bringing Heartless into Halloween Town. However, they are soon tamed by Jack Skellington and Doctor Finkelstein using one of the doctor's inventions.
Upon hearing from his minions, Lock, Shock and Barrel, that Jack was making an artificial heart to help guide the Heartless in the Halloween Festival, Oogie ordered them to steal it. Upon receiving the heart, Oogie swallowed it as soon as his uninvited guests, Sora, Donald, Goofy, and Jack Skellington arrived. He tried to summon an army of Heartless to due them in, but as the heart was not genuine, not as many Heartless flocked around him. Out of anger of being disrespected by such lower life forms, Oogie activated his Torture Chamber weapons and battled the group with his few Heartless.
Soon after being defeated by having his bugs spilt out of his body, Oogie succumbed to the powers of darkness (just as Jafar had) and took control over his entire manor. Merging with it, he attacked Sora and his friends once more. Sora battled the manor, and destroyed it (and Oogie Boogie) by destroying all the orbs of darkness covering him.
In Kingdom Hearts: Chain of Memories, Oogie Boogie appears as a figment of Sora's memories. He, like in the original game, attempts to steal Jack's research project, in this case, the Memory Potion. Eventually he succeeds in his plan, but fails again when he drank the potion and became terrified of what he remembered (though it is never quite explained what).
In Riku's story, he appeared (with no dialogue) as one of Riku's dark memories. He is, of course, defeated there as well.
In Kingdom Hearts II, Maleficent revived Oogie Boogie with the help of Lock, Shock, and Barrel. Unfortunately, Oogie Boogie suffered from anterograde amnesia and has difficulty remembering things since his resurrection. While he is capable of remembering Jack from before his defeat in Kingdom Hearts, and Maleficent as well, he forgets Sandy Claws' identity quickly, having just met him. Under Maleficent's orders, Oogie Boogie captured Santa Claus in Christmas Town to turn him into a Heartless and converts the present making machine into a Heartless making machine. Just as Sora, Donald, and Goofy discovered Oogie's plans, Oogie abandoned Maleficent's plans, saying that she was just cramping his style. Angered, Maleficent left, and Oogie once again battled against the heroes, failing once again, coming apart at the seams just like last time. This time, Donald stomped on Oogie's brain bug to ensure he would never come back again, but as Oogie has a tendency to return from the dead, his demise is still questionable.
Oogie Boogie appears in the Haunted Mansion Holiday at Disneyland and Tokyo Disneyland. In his debut year of the show, images of Oogie were spread throughout the Mansion, including appearing as the Gingerbread sculpture in the Ballroom and an Oogie cymbal monkey in the Attic to go along with the animatronic figure in the finale, who gives out Halloween Town Christmas toys through the mirrors which his henchmen pop up from.
In the Tokyo version, Oogie's dancing shadow appears in the darkened staircase/spider scene.
- Oogie Boogie is one of Disney's more popular villains, despite having no more than 10 minutes of screen time.
- Oogie Boogie was originally Dr. Finkelstein in a costume, but the ending changed as it came out of nowhere with a serious lack of any set-up.
- Oogie makes an appearance in Bleedman's webcomic: Grim Tales Down Below. Oogie wants revenge against Grim for becoming the Grim Reaper.
- Oogie Boogie could possibly be one of Disney's darkest villains, based on how he is supposedly a serial killer, gambler, and a cannibal.
- Oogie Boogie is the only member of Maleficent's group from the first Kingdom Hearts to show any affiliation with her in Kingdom Hearts II and he is one of the four villains in Maleficent's council of villains to have fallen to darkness, the other three being Jafar, Ursula, and Maleficent herself.
- When Oogie was defeated in Kingdom Hearts II, Donald stepped on what was apparently his "brain bug" just like what Santa did in the movie. However, as Oogie returned in the video game, Oogie's Revenge which was a sequel to the original film after his brain bug was squashed, his appearance in future installments is still possible.
- His death is, by far one of the most violent Disney Villains deaths, being skinned alive on screen.
- A small version of him can be seen in a Disney INFINITY trailer along with small versions of Lock, Shock, and Barrel.
