Sibling Team



Two (rarely, more) blood siblings of either gender working together as equal partners. Their business often involves ass-kicking, in which case they are likely to be Bash Brothers as well. The easiest way to tell that a sibling duo fits this trope is when they are most commonly referred as "the Surname brothers" or "the Surname sisters".

Brother-Sister Team is a gender-specific subtrope. Related tropes are Badass Family (for when the whole clan is in on the ass-kicking), Super Family Team (when the whole clan has superpowers), Unrelated Brothers (a Sibling Team in professional wrestling), and Wonder Twin Powers (for twins with superpowers that only work in concert). Contrast Cain and Abel.

Anime and Manga

 * The Elric brothers from Fullmetal Alchemist. They are state alchemists. Even if Al is not officially a state alchemist, they are working together as equal partners on both government missions and their personal quest for the Philosopher's Stone.
 * Also the homunculi in the manga are all brothers and sisters.
 * Xia Yu sisters from Full Metal Panic!: assassins/spies. Also, Creepy Twins.
 * Kouji and Tetsuya from Mazinger Z and Great Mazinger are adoptive brothers and Humongous Mecha pilots. When they are actually fighting their enemy instead of each other, they are a force to be reckoned with.
 * Tetsuya and Jun from Great Mazinger are also adoptive siblings. They overlap this trope with Battle Couple.
 * Duke and Maria from UFO Robo Grendizer.
 * The Thompson Sisters (possibly named for both the machine gun and the Thompson Twins) from Soul Eater. In their backstory they were criminals, until they met Death The Kid and became his partners.
 * Recent developments might see Liz and Patti working together as meister and Weapon, as Kid is currently imprisoned by Noah.
 * Confirmed in the Salvage arc. Patti is shaping up to be a menace as Liz's meister.
 * Gaara, Kankuro, and Temari of Naruto, who are sometimes called the Sand Siblings by the fandom, after their hometown. Early on in the series, they were actually closer to a deconstruction of this trope; Temari and Kankuro were both out right terrified of Gaara and only followed him out of a mix of obligation and fear. It isn't until post Time Skip that they start following the spirit of this trope.
 * N2R from Magical Girl Lyrical Nanoha, a unit made up of four of the Sisters, namely.
 * Also, the Liese Twins from A's, although they are twin familiars rather than a real family.
 * Natsumi and Kurumi in the Ranma ½ OAV, The One To Carry On. The former uses a rug beater to project razor-sharp freezing winds, while the other uses a hair ribbon several yards long to channel burning ki. The two sisters even have a Finishing Move Combination Attack that uses both aspects to blast their enemies away.
 * From the late manga, the sisters Pink and Link, who nearly poisoned the entire town.
 * In the anime, Shampoo's childhood friends Rinrin and Ranran.
 * From the first movie, the brothers Daikokusei and Daihakusei of the Seven Lucky Gods.

 * Oishinbo: The brothers in the Ramen and Gyoza volume.
 * The Hitachiin brothers from Ouran High School Host Club are more or less inseparable twins and often partners in crime. They've also been shown beating up punks together.

 * The are an example of Wonder Twin Powers.
 * Ikki and Shun from Saint Seiya at first started off as Cain and Abel. Finally in the last movie, Tenkai Hen~ Overture, they finally worked together.
 * If you go by the manga, you could say that this had been happening for a long time since all the bronze Saints are half brothers with Shun and Ikki being the only full-brothers of the group.
 * Panty and Stocking from Panty and Stocking With Garterbelt
 * The Kongo Twins of Eyeshield 21, though Agon gets far more attention then Unsui. There's also the Gonzales brothers of the Nasa Aliens.
 * The Pichu Brothers in the Pokémon anime.
 * Magikano
 * Gedou Otome TailThe Borden Twins i
 * The eponymous characters from Chinese anime Gourd Brothers. Seven brothers born from seven gourds on the same vine, each have one color from the rainbow. Rainbow...

Comics

 * Spider Girl plays with this a LOT. Fitting for a 'verse made up of Legacy Heroes.
 * Crazy Eight and Funny Face, a villainous example.
 * May also teams up with two annoying younger kids in spider costumes, but she's not really related to either of them.

Film

 * Joliet Jake and Elwood Blues AKA The Blues Brothers.
 * The creepy albino twins from The Matrix sequels.
 * The clone army from Star Wars could be an example. All the clones grow up together, at any rate, and individual troopers have other troopers that they are especially close to. If not, the four-man commando squads, as in Republic Commando, definitely count.
 * Trinity and Bambino, the "right and left hand of The Devil", respectively, in the Trinity series of Western films (played by Terence Hill and Bud Spencer, no less). Though Bambino isn't particularly happy about having a brother like that, they make one hell of a team when they join forces.
 * in The Prestige, who live their lives as one person for the sake of their magic act.
 * From Transformers: Revenge of the Fallen, we got the sisters Arcee, Chromia and Elita-1.

 * The Bagrov brothers from Brother, but especially the second movie.
 * The Mercer brothers, full stop.

 * The sons of Fëanor from The Silmarillion.
 * And Elrond's twin sons, who get very little mention in the Lord of the Rings main trilogy.
 * Rory and Coco in Little League Family. Rory catches and Coco pitches. As pitcher-catcher are almost a subteam in baseball, that makes them a literal as well as metaphorical team.
 * The Swallows and Amazons series is mostly about multiple Sibling Crews interacting with each other.
 * Most Enid Blyton protagonist groups are at least partially family-based. The Famous Five consist of three siblings, their cousin and her dog, the 'Adventure' group are two pairs of a brother and a sister, etc.
 * Teucer and Greater Axaj in The Iliad. They're half brothers, with Teucer being the bastard.
 * Georgia and Shaun Mason in Mira Grant's Feed are adopted, but every bit as close as blood siblings (they don't like to be apart, ever). They work together on their blog network and watch each other's backs when they go into infected zones.
 * Monza and Benna in Joe Abercrombie's Best Served Cold make a very efficient Sibling Team -- he's the people person, she's the one who fights. Together, they lead a band of mercenaries. It's implied that they are closer than most siblings.
 * Half-brothers Harry Dresden and Thomas Raith in The Dresden Files, wizard and vampire respective.
 * Niko and Cal Leandros. They even have a monster hunting agency.

 * Frasier and Niles Crane automatically team up for anything; from schemes to snag Frasier a date to elaborate, convoluted escapades that end up with them both being accidentally arrested for murder. The fact that they meet at least once a day to complain about their problems and beg the other to help them out contributes to this greatly, while neither the fact that their Sibling Rivalry frequently interferes with their teamwork, nor several dozen chewing-outs from their father for blowing things, has never stopped them.
 * From Super Sentai and Power Rangers:

 * GekiBlue and GekiViolet (Retsu and Gou Fukami) from Juken Sentai Gekiranger. Not carried over to Power Rangers Jungle Fury because Theo and RJ as siblings...?
 * Subverted in Power Rangers Zeo: It's heavily implied that Tommy's half-brother David is the Gold Ranger. He isn't. It's also teased that he will assume the powers. He doesn't.

 * J.C. and Paul Denton in Deus Ex and its sequel.
 * Billy and Jimmy Lee, the Double Dragons.
 * In the arcade version of Double Dragon 3, this trope is invoked literally by having the playable characters divided into four groups of different sibling teams (the Lee Bros., the Oyama Bros., the Urquidez Bros., and the Chin Bros.), essentially an excuse to allow more than one player to control the same character.

 * Edgar and Sabin Figaro from Final Fantasy VI. Royal siblings, no less. Having them in the same team together is only mandatory for one very brief period, but their most significant scenes involve both of them. Amusingly, while Sabin can be recruited before Edgar in the World of Ruin, but because he's optional, the (mandatory) scenes for Edgar's recruitment leave him mostly silent. You'd think he'd have some comments about his brother's Paper-Thin Disguise, but no.
