Our 20 favorite fictional brothers and sisters in movies and TV

This magical trio gave us the perfect sibling dynamic: Alex's sarcastic schemes, Justin's by-the-book nerdiness, and Max's delightful, vacant-stare chaos. They spent more time turning each other into sandwiches than actually mastering their powers, and it was glorious.

Raven's psychic visions always got her into trouble, and her younger brother Cory was usually right there beside her, mostly trying to turn her mishaps into a money-making scheme. The sibling banter was iconic, but let's be real, Raven's over-the-top outfits were the true star of the show.

The real chaos in Lizzie McGuire stemmed from Matt, whose sole purpose was to make Lizzie's middle school life a living nightmare.

Megan wasn't just a little sister; she was a criminal mastermind in a kid's body whose only goal was to ruin Drake and Josh's lives. Her elaborate pranks and effortless gaslighting made her one of the most hilariously evil siblings in TV history.

One was a cool-but-clueless musician, the other was a lovable, high-strung nerd. Drake and Josh's odd-couple chemistry and constant misfortune (usually thanks to Megan) were pure comedic gold.

Jackson was the poster child for lazy, slightly gross older brothers, and his entire existence seemed to be about mooching off his popstar sister. Their constant pranks and schemes, however, often led to surprisingly heartfelt moments that were classic sibling goals.

No two siblings have a more hilariously dysfunctional relationship than Stewie and Meg. One is a baby genius bent on world domination, and the other is the family's designated punching bag.

This trio basically defined sisterhood for a generation. You had the responsible one (DJ), the sassy middle child (Stephanie), and the adorable catchphrase machine (Michelle), creating a wholesome dynamic that was the heart of '90s family television.

The ultimate twin duo, Fred and George, were masters of mischief, chaos, and coordinated sweaters. Their unbreakable bond and dedication to creating a good laugh (even in the darkest of times) made them the most legendary siblings in the wizarding world.

The chaotic evil twin to Phoebe's chaotic good, Ursula Buffay, was a masterclass in hilarious indifference. Their brief, awkward interactions highlighted just how wonderfully weird Phoebe was by showing us what she could have been: mean, selfish, and a terrible waitress.

Carmen and Juni started as bickering siblings who couldn't stand each other and ended as world-saving super agents. Their journey from annoying brother and sister to an unstoppable team with jetpacks and rehydrating cheeseburgers is iconic.

One was the smooth-talking troublemaker, the other was the book-smart worrier, but together they were a force of comedic chaos at the Tipton Hotel. Their twin dynamic was the perfect recipe for elaborate schemes that would almost always end in disaster for Mr. Moseby.

The ultimate sibling rivalry gets a super-powered upgrade with Violet and Dash Parr. Their powers perfectly match their personalities — one is insecure and defensive (invisibility and force fields). At the same time, the other is an impulsive speedster, creating a dynamic that's both relatable and super.

This sisterly duo essentially reinvented the Disney princess formula by making true love about family, rather than a prince. Anna's relentless optimism clashing with Elsa's fear-fueled ice powers created a modern fairy tale that was all about the powerful, complicated bond between sisters.

The Dunphy kids were a masterclass in classic sitcom sibling archetypes: the ditzy, popular older sister (Haley), the brainy, sarcastic middle child (Alex), and the delightfully dim-witted younger brother (Luke). Their chemistry and constant low-stakes scheming were the hilarious, relatable heart of Modern Family.

For over three decades, Bart and Lisa Simpson have perfected the art of sibling rivalry. He’s the rebellious underachiever, and she’s the brilliant, misunderstood overachiever. Still, their moments of genuine connection prove they'll always have each other's backs — even if Bart has to steal a video game to do it.

No family gathering is more tense than a Roy family gathering, where the siblings are constantly jockeying for power and their father's approval. 

Wednesday Addams may be the queen of gothic deadpan, but her relationship with her younger brother Pugsley shows a rare, protective side. She's the only one allowed to torture him, and their hilariously one-sided dynamic is a perfect slice of sibling loyalty, Addams-style.

Known as "The Big Three," Kevin, Kate, and Randall Pearson gave us a masterclass in the messy, beautiful, and deeply complicated reality of sibling relationships. Their decades-spanning journey through triumph and tragedy was the emotional core of This is Us, proving that family bonds are both incredibly strong and incredibly complex.

These four siblings literally stumbled into a fantasy world through the back of a wardrobe and became kings and queens. Peter, Susan, Edmund, and Lucy's journey from ordinary English kids to the rulers of Narnia is a classic tale of courage, betrayal, and family bonds.
