[b]Personality:[/b] Lock (the devil) is the most vocal, demanding, and impulsive of the three, often exerting dominance and speaking for the group as a whole when needed. He is also petty and stubborn when he doesn't get his way, and the most likely of the three to throw a fit. Lock especially enjoys the bigger weapons in their armory, like the catapult and the cannon, and the most violent methods for accomplishing a goal.

Shock (the witch) is the most devious and practical of the three, often the voice of reason, and the force keeping her brothers somewhat in line and on target with their goals. While Lock may be more outspoken, she is the de facto leader of the group, and normally the brains of the operation, with her methods often being more practical. Being both the biggest and the oldest, she looks out for her little brothers, sometimes going so far as to let them hide behind her when the three are threatened. Shock especially enjoys sharp objects and her pet scorpions.

Barrel (the skeleton) is the most easy-going of the three, and comes off as the “dumb" one. He often lets his siblings pick on him and toss him around, but he takes it in stride as their peculiar brand of fun, and even enjoys it (because more than likely, he'll get them back later). Despite this, he is far from harmless, and should [i]not[/i] be underestimated. He may not show it as much, but he is every bit as clever and troublesome as his siblings. Barrel especially enjoys candy and pumpkins, and is often seen with a lollipop in one hand.

Lock, Shock, and Barrel generally work as a team, but have been known to cause solo trouble too. While they mainly play tricks for fun, they are cunning and devious. At the end of the day, though, they are still small children with the [i]mindset[/i] of small children, and will side with whomever is the scariest and/or gives them the most potential to cause mayhem. They can also occasionally be swayed with reason and patience, though it never lasts for too long. Perhaps whatever keeps them forever young also put limits on their maturity.

Being a team, Lock, Shock, and Barrel will do whatever is best for the team's survival. They are not only siblings, but each other's truest friends. While their overall loyalties may shift, their loyalty to [i]each other[/i] will not. They have the sort of relationship where one minute, they’re beating each other up, and the next, they’re happily plotting a trick together. If threatened beyond their means of handling a situation, their first instinct is to protect each other until the danger passes.

[b]Abilities:[/b] All three of them are proficient with their slingshots, can use anything in their armory to its fullest potential, and can improvise and play off the others very well, to the point they complete each other's sentences, make similar gestures, and have silent agreements. Even for children, they are small, which allows them to get into many places they shouldn't be. Lock and Shock both have sharp teeth, though all three of them aren’t above biting if it means escape.

Lock favors an ordinary plunger, and can use it not only as a makeshift weapon, but enjoys slamming his enemies from above with it. Being an eternally small child, he has the speed and stamina that comes with youth.

Shock uses a broom as her main weapon and is adept with it. Being a witch, she can also use a little magic, but only in small bursts and with complete concentration, as she isn't trained in it like the other Halloween Town witches. Since that takes work, she prefers more hands-on means of trouble, and is very fast, a necessary skill when running from your angry victims.

Barrel is the most competent with his slingshot, able to fire it more rapidly than his siblings. Despite his more rotund figure, he is just as fast and agile as his siblings, though he's often the easiest to catch because of his shorter legs. Barrel comes off as the most innocent and naive, and will milk it for all it’s worth.

[b]Flaws:[/b] Being small children has its obvious drawbacks if one actually manages to catch one of them. Their small size and weak strength makes it easy to overpower them and force them to temporarily behave. Due to their work with Oogie (and the few times they crossed the line with Jack), fear and intimidation works [i]very[/i] effectively against them, to the point of instant submission if done correctly.

All three of them have violent tendencies and a love of trouble. While they usually know [i]exactly[/i] what they're doing, there [i]are[/i] times where they legitimately don't understand how bad their mayhem can get, as they just think it was a funny prank. They’re cowards, and will turn tail (sometimes literally in Lock’s case) when they sense they’ve gotten in over their heads with their troublemaking.

Lock, Shock, and Barrel [i]can[/i] be reasoned with, but they have a tendency to double-cross, especially if breaking a promise yields more “fun” for them. In fact, unless you can see their hands (because they'll often cross their fingers behind their backs when making a promise), assume they're lying. Even then, proceed with caution, because a promise they're actually sincere about is only good until a better, more fun deal comes along (or if the new deal-maker is more terrifying). The three of them are wildcards, and will alter their goals for their own benefit. 

As mentioned, Lock is the pettiest and most prone to throw a fit when he doesn't get his way. Where Lock is more likely to throw a [i]fit[/i], Shock is more likely to start a [i]fight[/i]. Being the most practical, she is [i]also[/i] the most manipulative, and will turn sugary sweet to get her way (not that it always works). Barrel is the easiest of the three to sway over, be it from his siblings or someone else. While all three of them are prone to it, Lock and Shock in particular fight the most, often for dominance in the group, while Barrel may or may not take advantage of it.

While they do occasionally cause solo trouble, Lock, Shock, and Barrel are a functional set that depends on completion. They are never separated from each other for very long, to the point where if you find one by themselves, the other two probably aren't too far behind. Taking one of the three away for too long will throw off their balance, and may even cripple them due to their dependency on each other.

...Not that the remaining two won't drop everything to hunt their sibling down and rain unholy vengeance on any unlucky idiot responsible for it, but it [i]is[/i] a temporary reprieve from their mayhem if one finds it worth the risk.

[b]Companion(s):[/b] Their walking claw-footed bathtub. It seems to know what the threesome wants, and will follow their direction and needs, be it a leisurely stroll into town, equipment transport, or a getaway vehicle. It acts like a well-trained horse.

Shock also has three pet scorpions that may or may not solely be used for mayhem.

[b]Brief History:[/b] Lock, Shock, and Barrel worked for Oogie Boogie for as long as anyone can remember. They are known as “Halloween's finest trick-or-treaters,” and professional kidnappers. Their old lives - if they ever had them - have long since been forgotten, though it’s rumored they were naughty children who were “spirited away" by the boogieman and forced to work for him. While Oogie was their master, and they legitimately enjoyed some of their work under him (and the occasional reward of snake-and-spider stew), Lock, Shock, and Barrel’s loyalty to him was primarily out of fear. No matter how much “fun" they had under his wing, it was always accompanied by a threat of being eaten alive, and physical violence. The trio often gave him offerings between jobs to keep him appeased and to “stay on his good side.”

On occasion, they helped out Jack, such as with their mission to kidnap Sandy Claws (whom they brought to Oogie as an offering, despite their promise to Jack to leave him out of it). When Jack allegedly perished in the Christmas Eve disaster, he caught the trio down in the ravine under their tree house, watching Oogie torment Sally and Sandy Claws. After receiving a good scare from Jack, the trio abandoned their post and fled back into town. Despite their prior nastiness, Lock, Shock, and Barrel alerted the Mayor that Jack was still alive, even before they learned that he took down their master.

After Jack defeated Oogie, the trickster trio, freed from the boogieman’s influence, became less aggressive and more playful, but are still (rightfully) feared by certain members of the town, particularly the Mayor. While no one is [i]completely[/i] immune to their pranks, the only citizen they more or less leave alone (beyond maybe disorganizing her spools of thread) is Sally, both for her patience and kindness with them, and due to Jack’s potential wrath if they take advantage of it.

With Jack and Sally’s guidance, Lock, Shock, and Barrel currently somewhat resemble decent Halloween Town citizens with an occasional prank thrown in just to shake things up. They even sometimes get along and play with the other Halloween Town children. While they'll never [i]fully[/i] be rid of their devious, troublemaking ways, the threesome really [i]are[/i] doing their best at the moment to contribute to Halloween.

...For now.
