Think Twins

Go To

Twins are often treated as the "thinking engine" who come up with plans (be those devious or truly smart) because, well, there are two of them, and they are on the same wavelength (more so than just regular friends) so they can come up with things among the two of them more effectively than other two characters, which would involve a lot more explaining yourself and arguing.

Putting these guys on Mission Control is also quite logical - often you need to show that technical equipment takes more than one person to operate, but both people essentially do the same task, and it would be a waste to characterize separately two people who essentially fulfill the same role on the team (or, on the other end, sacrifice two interesting characters to do one job).


May overlap with Trickster Twins.

    Anime and Manga 
  • In K, the Weismann twins were this, as the head scientists working on the Slates, even at a young age. Claudia dies and Adolf becomes immortal, but retreats to live in a blimp for 70 years because of his grief. When he does return and must solve a new problem with the Slates, he relies on Claudia's notes a lot, and says she was always the smarter one and it's incredibly hard for him to do this without her.
  • In Project Arms, there are Al and Jeff Bowen, evil genius identical twins until Al's Heel–Face Turn and Jeff's death, and also Katsumi and Kei, who are identical female twins; Kei's The Chick, and Katsumi's a Damsel in Distress and a major plot point.
  • Jin and Mikoto Ishino from Tomica Hyper Rescue Drive Head Kidou Kyuukyuu Keisatsu are both shown to have very high mathematical skill. In one episode, they're seen playing a prime number game just for fun.

    Fan Fic 
  • In Harry Potter fan works, Luna Lovegood's twin sons, Lorcan and Lysander, are often depicted as this. Not surprising, as their parents are both world-renowned naturalists and their mother at least was in Ravenclaw House during her schooling (the House that values intelligence above all else).

    Film — Animation  
  • 3 and 4 from 9, also Single-Minded Twins (and, if it means anything, mute).
  • The Barnabys from The Willoughbys are into engineering contraptions. They're fascinated when they see an entirely automated candy factory and in the third act use it to engineer a balloon airship that runs on sugar.

    Film — Live Action  

  • Fred and George Weasley from Harry Potter, even though they're more Trickster Twins, it did take a certain amount of brain power to make all the Weasley Wizard Wheezes. They do pretty poorly in school, though, if only because they don't care about their grades.
  • Beltira and Belkira of the Belgariad and Malloreon. They spend most of their time in the Vale of Aldur trying to decipher a multitude of complex prophecies, while the other sorcerers act on what little information they can find.
  • Isadora and Duncan Quagmire of A Series of Unfortunate Events are as intelligent as main characters Violet and Klaus Baudelaire and help them come up with plans to escape Prufrock Prep. Subverted in that they’re not twins; they’re two of a set of triplets, who supposedly lost their brother in a house fire.
  • In Robert A. Heinlein juvenile Time for the Stars, Pat and Tom are two of a selected group of twins and triplets who can communicate telepathically with each other.

    Live-Action TV 

    Western Animation 
  • Doug: Al and Moo Sleech
  • Detention: Orangejella and Lemonjella LaBelle
  • The "tweebs" from Kim Possible. Granted, basically everyone in their family is a genius, including Kim (who's simply not as into science as the rest of her family is). They also end up starting high school at only twelve.
  • Johnny Test: Susan and Mary Test, Johnny's older sisters.
  • A set of overachiever twins seen in one episode of Static Shock.
  • Thunder Cats had Wily Kit and Wily Kat, who, as their names suggest, were quite wily. Lion-O had to face the pair of them to overcome the Trial of Cunning.
  • The Platypus Brothers from Tazmania.
  • Rhona and Andy in Iron Man: Armored Adventures. Subverted in that Rhona turns out to be an only child and that Andy's an android she built.

    Real Life 
  • Can be truth in television, as research studies of twins can attest.
