Woe to the fictional parents of the Trickster Twins. They are a set of siblings that are always up to no good in pursuit of sadistic delight. They are a magnet for trouble (either attracting it or causing it) and have to find a way through a series of convoluted plans to escape the situation.
The traits most common to a set of Trickster Twins is that they're pranksters or entertainers. Their antics are usually for comic relief, but other times, their tricks can be far more sinister. Trickster Twins also tend to have the good-natured compulsion to pick on or tease the rest of the cast. If they target a single character out of the entire cast, that victim is usually the Butt-Monkey.
- Hikaru & Kaoru Hitachiin in Ouran High School Host Club. (They even appear as Cheshire Cats during a homage to Alice In Wondeland.)
- Shion & Mion in Higurashi: When They Cry. Sometimes, it's funny. Other times, it's not funny at all.
- Fuuka & Fumika Narutaki in Mahou Sensei Negima!. Notably, Fumika is more reserved and often states that Fuuka's pranks aren't such a good idea, but she always gets dragged along and always gets into it anyways.
- Kazuo and Masao Tachibana in Captain Tsubasa have some traits of this, specially since both of them are deadpan snarkers. They have even come to weaponize their trickery, as many of their shared in-game tricks relay on acrobatics and their Think Twins antics.
- Ami and Mami Futami from The Idolmaster can be read more about below. In Petit iDOLM@STER, their puchi counterparts take this further. Each puchi has a single strange power or exaggerated trait, and for Koami and Komami, it's that they do little else but play over-the-top pranks on everyone else, even when there was no logical opportunity for them to have set it up.
- Pride High has Smash and Crash. They finish each others' sentences, can trade places with one another in an instant (which they slyly use while wrestling) and remain the most devious of the the prime group of antagonists.
- In Sight Ukitake's zanpakuto, Sougyo no Kotowari are a very mischevious pair of twins who Speak in Unison, play pranks on Ichigo and play Kidou Tag which consists of them firing kidou at Ichigo while he runs away.
- Brave has identical triplets Harris, Hubert and Hamish. Among their antics, they steal cakes, cut off part of a sleeping guard's mustache, and tie their father's peg leg to a table so he flips it when he gets up.
- Harry Potter: Fred and George Weasley cause humorous trouble for their family and for Hogwarts. When they grow up, their deviousness becomes the seed for their own company; Weaseley Wizard Wheezes, a joke shop.
- Bonnie and Beanie, the little teleporters from Theodore Sturgeon's More Than Human.
- Hugal and Monan from the Dungeons & Dragons Eberron novel The City of Towers thrive on twisting mind screws.
- The Stoll brothers from the Hermes cabin in Percy Jackson and the Olympians. Not twins, technically, but nearly identical.
- "Trouble Twins" Florida and Dallas from Ruby Holler, although it's justified in that they're mistreated by the owners of the orphanage they live in and strike back in the only way they can; Dallas is a Nice Guy and Florida is a Jerk with a Heart of Gold.
- Bertie's cousins Eustace and Claude in Jeeves and Wooster.
- A Song of Ice and Fire: Who can forget all the crazy antics of the Lannister twins? Incest, pushing kids out windows, regicide...
- Adam, Byron and Jordan from The Baby-Sitters Club are Trickster Triplets.
- Marilyn and Carolyn Arnold in their first appearance, but it turns out they're just acting out because they're sick of being treated like one person. They're much better when they show up later.
- The relationship between the two eponymous rascal boys in Wilhelm Busch's Max and Moritz is not specified, but they have a common uncle, which indicates they are either cousins or twin brothers.
- Mufus and Bufus Doolan in Robin Jarvis' Hagwood books.
- Bill and Ben in The Railway Series. Edward and BoCo are the only ones who can keep them in order.
- Donald and Douglas had a bit of a tricksy streak when they first arrived on Sodor, pulling a few Twin Switch gambits to each get the other out of trouble, but once their place on the island was secure for both of them, they toned this down.
- Zack and Cody from The Suite Life of Zack and Cody.
- Hans and Fritz, the Katzenjammer Kids.
- The Adventure Zone: Balance: Taako and Lup.
- The Blossom Twins in the UK Wrestling scene and Ohio Valley. Unlike most Tag Team Twins, they're more mischievous than actively malevolent.
- Mungojerry and Rumpleteazer are a notorious couple of cats, knock-about clowns, quick change comedians, tight-rope walkers and acrobats! However, it is argued among Cats fans whether they are twins, brother and sister or something else entirely, but due to their very almost identical markings and that they often hang out together it is mostly assumed that they are twins...
- Dee and Dum from Heart no Kuni no Alice. Their tricks range from the innocent to the... not so much.
- Pokémon Black and White: Tornadus and Thundurus, both of which have the Prankster ability.
- Duke and Luke Crabtree from Sir Basil Pike Public School, who reenact the old Knights and Knaves puzzle on the player character.
- The Idolmaster has Ami and Mami Futami, who also provide the image for this page. They enjoy playing pranks or teasing other people and, before Mami grew out her hair, they looked identical. Their main stick in the first game was to switch roles repeatedly and the producer had to figure out when it was Ami and when it was Mami. They toned down a little bit in Idolmaster 2 on the pranking part.
- Phoenix Wright: Ace Attorney – Spirit of Justice: Bonny and Betty de Famme are both Stage Magicians who use Twin Switch in their tricks.
- Subverted with Vivi and Linda in The Legend of Heroes: Trails of Cold Steel. Vivi is a prankster, but Linda is a Nice Girl who doesn't want anything to do with it, and will apologize to anyone her sister pranks. Vivi will often pull a Twin Switch on her own to troll people, which annoys Linda to no end.
- Jay and Elle from Puyo Puyo Tetris.
- Elijah and Mijo from Lunarosse engage in a bit of this when you first meet them, as they make you play a guessing game in order to pass to Sherwood Village.
- The Cake twins in Slice of Life have shades of this, particularly Pumpkin.
- The Arrow twins in Ava's Demon show this in their short time in the comic thus far.
- Vex'ahlia and Vax'ildan from Critical Role, each in their own ways. Vax is both the party rogue and a fan of pranking his fellow party members. Vex is a notorious haggler and flirt, and also fights with a number of neat trick arrows.
- Taako and Lup from The Adventure Zone, presumably coming from their rough childhood spent in caravans.
- Lifty and Shifty from Happy Tree Friends are of the more sinister variety, being thieves.
- Tommy and Timmy Tibble of Arthur.
- Phil and Lil from Rugrats
- Jim and Tim, the Tweebs, from Kim Possible, also doubling as Think Twins.

- Edgar & Ellen are twins who spend their time pranking the other residents of their town.
