~ Lock, Shock and Barrel, before they kidnap Santa Claus.
Lock, Shock and Barrel are the secondary antagonists of Tim Burton's 1993 animated stop-motion film The Nightmare Before Christmas. They are Oogie Boogie's former henchmen.
In the film, Lock was voiced by Paul Reubens (who also played Amilyn in Buffy the Vampire Slayer), Shock was voiced by Catherine O'Hara (who also voiced Sally in the same movie), and Barrel was voiced by Danny Elfman (who was the film's score composer, and also voiced the Clown and Jack Skellington's singing voice). In the Kingdom Hearts series, Lock was voiced by Jess Harnell, Shock was voiced by Kath Soucie, and Barrel was voiced by Jeff Bennett.
Lock, Shock and Barrel were picked by Oogie Boogie to stop Jack Skellington, whom the earlier holiday known as Bug Day was rejected.
The Nightmare Before Christmas
Lock, Shock and Barrel were first sent by Jack Skellington. The Mayor of Halloween Town was the first to encounter them, upset that Oogie Boogie's henchmen arrived, but they told him that Jack specifically asked for them by name.
Jack then told them his plan, which was to capture Santa Claus. However, he specifically told the trio that the plan was top secret, and to not involve Oogie Boogie in it. They responded affirmatively, but crossed their fingers behind their backs to show that they were being dishonest.
When they arrived at their lair, they performed the number "Kidnap the Sandy Claws", in which they came up with some plans about what to do with Santa when they capture him. A few notable plans included locking him up for 90 years, throwing him in the ocean, hitting him with sticks, boiling him alive, setting a trap, and blowing him up with a cannon. During this musical number, they also boiled a caged insect alive and sent it down Oogie's sacrificial chute.
On their first try, they took the Easter Bunny, much to Jack's frustration. Jack told them that Santa was behind the door shaped like a tree. The trio got in a brief physical fight before Jack reprimanded them, insisting that the Easter Bunny was to be sent back to Easter Town, they correctly capture Santa this time, and to treat Santa nicely when they capture him. Lock, Shock, and Barrel left, accepting Jack's request.
About a month later, they finally found Santa Claus, bringing him to Halloween Town to meet Jack. Soon after, they sent Santa Claus to their lair, and began to send him down the chute. While they weren't sure if Santa could go down the chute, Lock insisted that Santa could fit through anything, and soon proved himself right.
Following Oogie's sudden death, they appeared to have redeemed themselves, finding out that Jack survived the crash. They helped Jack, Sally, and Santa Claus escape Oogie's lair, along with the Mayor. They were among the citizens surprised when it started to snow in Halloween Town, and were last seen having a snowball fight.
Lock, Shock and Barrel learned that Jack is out of town and decided to resurrect Oogie Boogie allowing him to inflict terror over Halloween Town once again. Oogie kidnaps the Holiday Leaders for Valentine's Day, St. Patrick's Day, Thanksgiving, Independence Day, and Easter, and imprisons them in his underground lair. Lock, Shock, and Barrel are entrusted with hiding each of the seven Holiday Doors in each area of the town where they wouldn't be discovered. They also raise armies of ghosts and skeletons to counteract Jack's inevitable attempt to fight upon his return. Shortly after Jack comes back, he encounters the trio in the Graveyard, and they refuse to reverse the damage.
Lock engages him in battle and retreats after his skeletons are defeated. When Jack goes to free Sally, Lock fights him once more, this time entering the fray himself, but loses again. Soon after, when Jack attempts to free Dr. Finkelstein, Shock confronts him with an army of ghosts but retreats upon losing. She confronts him again at the Doctor's Lab, using giant metal balls to deter Jack from climbing the spiral ramp to the lab. Like Lock, Jack warns her to stop helping Oogie, and like Lock, she agrees but crosses her fingers behind her back. They're next seen at the Pumpkin Patch, where Barrel forces Jack to navigate a maze he's created to reach him in the Big Pumpkin Head. Upon succeeding, Jack fights Barrel and the skeletons under his control, taking from him the Thanksgiving Door and the key to the Residential Area. When Jack reaches the Mayor's house, he finds Lock, Shock, and Barrel on the roof, where they face off one last time.
Upon their defeat, Jack claims the Independence Day door, but the trio uses a trick switch to open a void beneath him, dropping him into Oogie's underground lair and remarking, "Looks like he really fell for that one." They are not seen or mentioned for the remainder of the game after this.
Kingdom Hearts Series
As well as their role in the film, Lock, Shock, and Barrel has also appeared as bosses in various video games, the more notable probably being Kingdom Hearts.
In Kingdom Hearts, they stole an artificial Heart from Dr. Finkelstein to give to Oogie. However, they were soon captured, without the Heart. After their battle, they reluctantly revealed tips on how to defeat Oogie. It was assumed that they left the mansion afterwards, since they were seen in Kingdom Hearts II.
Kingdom Hearts II
In Kingdom Hearts II, it was revealed that the three became Dr. Finkelstein's assistants. When they went out to play, they came across Maleficent and told her of Oogie Boogie's fate. Maleficent revived Oogie and gave them control of the Prison Keeper Heartless as a distraction for Sora and company.
In the second visit, they were blamed for stealing Christmas Presents from Santa. In the inevitable chase afterward, the heroes discovered the truth when they told them about Dr. Finkelstein's experiment.
Their names were a play on the figure of speech "lock, stock, and barrel", meaning "all", "total", and "everything". The phrase was derived from the components of a musket.
Although Lock, Shock and Barrel are Oogie Boogie's henchmen, they are never seen interacting with him onscreen, considering that Oogie is secluded on his lair. Allthough they do interact with him in the prequal.
It is indirectly stated in the song "Kidnap the Sandy Claws" that the trio might even be somewhat afraid of Oogie, another possible reason as to why they're never seen interacting with him.
In Kingdom Hearts, after the mutation of Oogie's lair, it is unknown what happened with Lock, Shock, and Barrel, because they were defeated by Sora inside Oogie's lair and presumably knocked out. However, in the other games of the series, it is revealed that they somehow survived. So, this means that they are still alive.
In The Nightmare Before Christmas: Oogie's Revenge, it is unknown what happened with Lock, Shock, and Barrel, because they transport Jack to the Christmas Town before they were never seen again in the video game. However, they could probably be exiled from Halloween Town by Jack.
In a deleted scene of the film, Lock, Shock, and Barrel are surprised by Jack while they are in the elevator cage watching how Oogie talks with Santa and Sally. Scared by Jack, they jump off the cage to the abyss, leaving their fates unknown. Albeit the scene was filmed and later deleted, this scene explains why Jack found the elevator cage under the bridge when he came to rescue Sally and Santa or why Lock, Shock and Barrel became aware that Jack hadn't been killed.
It is possible that the scene was deleted not only to not make Jack look like a murderer, as Lock, Shock and Barrel are implied to fall to their deaths in this version, but because it would have made Lock, Shock and Barrel to look too sadistic and even cross the Moral Event Horizon, as before Jack surprises them, they celebrate that Jack has died upon hearing the Mayor's announcement and don't look worried that Oogie plans to dispose of Santa and Sally.
In the Russian version of the film, the trio was voiced by an all-male rock band, meaning that Shock was voiced by a male voice actor.
Despite only being the secondary antagonists, they have more onscreen appearances than Oogie Boogie does.
Their names were only mentioned once in the movie, which was in the first scene they appeared in.
