- Mycroft: "For goodness' sake! I occupy a minor position in the British Government."
- Sherlock: "He is the British Government – when he's not too busy being the British Secret Service or the CIA on a freelance basis. Good evening, Mycroft. Try not to start a war before I get home, you know what it does for the traffic."
- ―A Study in Pink
Mycroft Holmes is the older brother of Sherlock Holmes, and is seven years his senior.
Mycroft claims to merely "occupy a minor position in the government". However, according to Sherlock, he occasionally is the British Government, functioning as the control centre or "clearing house" for all government actions and decisions. Mycroft tells John that Sherlock may even consider him his arch-enemy. Sherlock neither confirms nor denies this statement.
There are signs throughout the series that Sherlock Holmes is right about Mycroft's high position in the UK Government, such as his ability to control CCTV cameras at will. He also is shown to have the ability to hack into cash machines and make them display messages he wants the user to see.
Mycroft has a habit of kidnapping people to talk to them, instead of using more conventional methods. He has very good connections; it is implied by Sherlock that he knows the Queen, when Sherlock starts to play "God Save the Queen" on his violin, and he is able to pull strings to allow Sherlock access into a top secret military base. In this episode, it is also asserted that his priority level is "Ultra". Unlike his brother, Mycroft is also known to only text when he cannot talk.
Mycroft occasionally warns John when he thinks that it is a "danger night" with Sherlock ("A Scandal in Belgravia"), and has John search the house. On those nights, he needs John to stay at home with Sherlock (and look out for him). However, Sherlock knows that John has been searching his stuff, and may be aware of what Mycroft has done (and asked John to do).
- "Balance of probability, little brother."
- ―Mycroft to a young Sherlock [src]
Despite the hostility/rivalry between them, Mycroft cares greatly for his brother, although his ways of watching out for his brother are unorthodox in the extreme. He is an almost entirely cynical, socially detached, and calculating individual with an exceptional degree of self-control. His analytic abilities are incredible, beyond the standards of Charles Augustus Magnussen himself, despite the fact that Mycroft relied on the latter most heavily.
His powers of deduction surpass that of his younger brother, Sherlock, when he discovered what had happened to a hiker by simply "glancing over the police reports". At one point, he and Sherlock have a deduction battle and, as always, he wins. He has always been 'the smart one' according to them both, which caused Sherlock to believe that he was an idiot, until they met other children. He also corrects Sherlock's deduction of John and the lilo, by saying it was the sofa. However, even though he is more intelligent, he is also lazier and he could do the investigations himself, but that would require 'legwork', which he was not very keen on.
After he has first witnessed Sherlock and John working together, he tells his assistant to update Sherlock and John's surveillance status to level 3, implying that he already had governmental surveillance on Sherlock. In tandem with his high intelligence, his self-confidence and mental resilience are almost inhuman, as he is practically immune to even his own brother's probing.
Mycroft is shown to be much more capable of faking normalcy than his brother, and where as Sherlock is ostracised for his behaviour, Mycroft is highly respected by his (seeming) peers. However, he is apparently just as cold as his brother, once informing him categorically that caring was not an advantage.
He is thought to be very lonely and isolated. Sherlock has said this to him too, as even Sherlock has friends but Mycroft has none. Mycroft believes himself to be "living in a world of goldfish", showing how he believes himself to be surrounded by people of lower intelligence.
However, despite his lack of romantic interests, it is suggested that he is not a virgin unlike his brother Sherlock. When in Buckingham Palace, upon telling his brother not to be alarmed as Irene Adler's job was to do with sex, Sherlock replied "Sex doesn't alarm me", to which Mycroft sarcastically asked him "How would you know?". On other occasions, Irene Adler had informed the Holmes brothers that Moriarty's nickname for Mycroft was "The Iceman" whereas his nickname for Sherlock was "The Virgin". Also, during the wedding of John and Mary, Sherlock had phoned Mycroft just after Mycroft had finished exercising and asked him why he was out of breath. He then stated that he had either caught Mycroft in a 'compromising position' or he had been working out again. He might work out primarily to keep his body healthy and thus his mind sharp as it seems he is quite physically weak. This is demonstrated when he condescendingly referred to Sherlock as "brother mine" and Sherlock effortlessly twisted his arm up his back. John even warned Mycroft that Sherlock could easily injure him severely and Mycroft reluctantly departed, indicating he is capable of picking and choosing his confrontations, a trait Sherlock either lacks or dismisses.
Again, despite his seeming lack of empathy, he still cares greatly about his younger brother Sherlock as seen in the first episode, when he had informed John that he "worries about him constantly". In another episode, Sherlock and Mycroft are seen to be smoking outside their parents' house on Christmas day, where Mycroft says to Sherlock "Your loss would break my heart".

- "Too much history between us, John. Old scores. Resentments."

- "Nicked all his Smurfs? Broke his Action Man?"

- "If you seem slow to me, Sherlock, can you imagine what real people are like? I'm living in a world of goldfish."
- ―Mycroft to Sherlock [src]
- "I am the smart one."

- "Mycroft is the name you gave me, if you could possibly struggle all the way to the end."
- ―Mycroft to his mother, when addressed by her as "Mike"
- "Both of us thought you were an idiot, Sherlock. We had nothing else to go on, until we met other children."
- ― Mycroft to Sherlock
- He is on a diet, which Sherlock comments about frequently. He is also made fun of for his working-out.
- He wears a ring on the ring finger of his right hand. It is unknown if this is symbolic of anything. Show co-creator and actor of Mycroft, Mark Gatiss, has stated that it is not a wedding ring, but that he likes to think there is a story behind it.
- He does not appear during the "Unaired Pilot", and his lines during the ending scene are given to DI Greg Lestrade.
- Mycroft is a member of the Diogenes Club, a private establishment that requires silence at all times, as in the canon.
- Irene Adler revealed that Jim Moriarty's nickname for him was "The Iceman".
- He and Sherlock may have had another sibling, as he was speaking to another government official about the country needing Sherlock Holmes. As he dismissed the official about feeling sentiment for Sherlock, he briefly told the official "you know what happened to the other one".
- It is heavily suggested that Mycroft might just be smarter than Sherlock in many respects, his presence in Sherlock's mind palace after the latter was shot corroborates this even further.
- He is considered by those in his rarefied circle to be the most powerful person in England.
- Sherlock tells John that Mycroft has OCD.
- Mycroft is fluent in Serbian. He appears to be very adept at learning languages, claiming to learn Serbian in only a few hours.
