Background
Oogie is the embodiment of a child's worst nightmare. His burlap sack of a body is animated by a hive mind of insects and other creatures. The Nightmare Before Christmas: The Pumpkin King reveals that Oogie and Jack Skellington's rivalry traces back to one year before the events of the film. After hearing stories about the supposed "Pumpkin King" of Halloween Town, an envious Oogie Boogie became obsessed with outclassing Jack as the scariest ghoul there is. His manner of doing so developed into a coup to take over Halloween and rebranding it as "Crawloween"—a holiday dedicated to bugs. Oogie's scheme was foiled by Jack, who punished Oogie by confining him to his lair beneath Lock, Shock, and Barrel's treehouse.

The Pumpkin King


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, or "Crawloween." That was (most likely) forgotten by the people of the real world and he became the "recluse" of the Tree House outside Halloween Town. Unfortunately, Oogie caught wind of Jack being named the "Pumpkin King" and decided that Halloween Town would be the new "Bug Town." He and his army of insects invaded the municipality 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 confined to his underground lair.

In the 2005 video game The Nightmare Before Christmas: Oogie's Revenge, Lock, Shock, and Barrel sewed Oogie back together after Jack left town searching for new ideas for Halloween. Oogie 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 through him 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, Barrel, and his new army of monsters, 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 was nearing fruition, the entire town had been booby-trapped and the citizens were afraid to set foot in 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 loudspeaker 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.
