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.
Examples:Anime and Manga
- From the manga Project Arms, there are Al and Jeff Bowen, evil genius identical twins until Al's Heel-Face Turn and Jeff's death, and also Katusmi and Kei, who are identical female twins; Kei's The Chick, and Katsumi's a Damsel in Distress and a major plot point.
- 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).
- The twins in Men In Black
- 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.
- 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.
- Power Rangers RPM had genius twins Gem and Gemma, though their intelligence was heavily overshadowed by the fact that they were Cute and Psycho Cloud Cuckoolanders. They instead collectively filled the Sixth Ranger role, leaving Mission Control duties to Dr. K.
- The Edison Twins.
- The Bynars from Star Trek: The Next Generation are an entire alien species of cyborg Think Twins.
- Though they aren't related, Leopold Fitz and Jemma Simmons (colloquially known as Fitz-Simmons) on Agentsof SHIELD qualify.
- Doug: Al and Moo Sleech
- Detention: Orangejella and Lemonjella LaBelle
- The "tweebs" from Kim Possible. Granted, everyone in the Possible family is a genius, but the twins are significantly smarter than their older sister. And also twelve. And in high school.
- Johnny Test: Susan and Mary Test.
- 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's an only child, and Andy's an android she built.
- Can be truth in television, as research studies of twins can attest.
