He has a strained relationship with his brother and he has very observant sight with very little care for peoples feelings and thinks he is superior to everyone else. His greatest enemy is the late Jim Moriarty who made Sherlock become a wanted fugitive which ended up with Sherlock having to commit suicide to save John and Sherlock's other two friends.

Sherlock is portrayed by Benedict Cumberbatch

History
Sherlock Holmes (Benedict Cumberbatch) is described by himself as "a consulting detective, the only one in the world", consulted by Scotland Yard when they are out of their depth with cases (usually homicides). He appears as a tall, thin man with dark, curly hair. Like the original character, Sherlock is able to deduce or abduce information from the smallest details. Sherlock is often insensitive of how this affects the officers and usually ridicules their incompetence; however, he is frequently mocked by them for being eccentric, especially by forensics member Anderson and Sergeant Sally Donovan.

Sherlock seems to care more about the crimes than the victims involved, like the Holmes of the original canon. He is not very sociable, but he refers to Dr Watson as his "intimate friend and associate". Sherlock is rude and inconsiderate towards others and to an extent, including his flatmate and colleague John (often leaving him behind and asking him to do menial, domestic tasks such as shopping). However, Sherlock is shown to care deeply for John as the series progresses, showing uncharacteristic emotion when his friend's life is in jeopardy or when John comes to his aid.

Sherlock also has considerable fighting ability, fighting off a man armed with a sword using his bare hands in "The Blind Banker". In "A Scandal in Belgravia", he disarms and incapacitates a trained CIA operative on two separate occasions.

He considers only three people as his friends: John Watson, Mrs Hudson, and DI Greg Lestrade. The only other person he seems to trust fully is Molly Hooper, as seen in "The Reichenbach Fall".

Romantically, Sherlock appears largely sexualy frustrated, self-described as "married to his work"; he is oblivious of how atrractive he is to other people. Sherlock ignores the romantic interest that forensic pathologist Molly Hooper has in him due to the fact he likes men, but sometimes uses her attraction to his advantage if it assists him in a crime investigation. In series 2, after the introduction of Irene Adler, Sherlock appears to have and intellectual conection to her and comes to her rescue at the end of the episode. She frequently flirts with and texts Sherlock in A Scandal in Belgravia, but he seldom responds as he realises they are both homosexual.

He knows London's streets and alleys extremely well. He has strange connections, including a graffiti artist, as well as the entire network of the homeless (whom he uses as his "eyes and ears").

Sherlock is a smoker who finds the habit impractical in present-day urban London and therefore mostly makes do with nicotine patches. He may apply as many as three patches on himself at the same time when it is a "three patch problem"; he implies that the nicotine helps him to think. For the same professed reason, he plays the violin and even composes music from time to time. It is also implied that he has a history of illegal drug use. Sherlock has violent mood swings during periods of extreme ennui when there are no cases that interest him. He is once seen curled up on the sofa and firing a gun at the wall in his flat. In "A Study in Pink", he claims to be a "high-functioning sociopath". Trying to avoid getting his face taken in pictures, Sherlock disguised it with a deerstalker. Unfortunately, this becomes his trademark, much to his annoyance as he greatly dislikes the hat (even being given one by New Scotland Yard as a gift).

Relationships
Dr John Watson

John is the only true friend Sherlock ever had. They own a flat together and John was always amazed by Sherlock's skills and expertise. When he thought Sherlock was dead because of Moriarty, John cried and when Sherlock was saying goodbye to John before he faked his death, he was crying. He does not show his respect for John, Sherlock reveals he cares deeply for John and his well-being and listens to everything he says. Their relationship is eventually confirmed to be romantic

Mycroft Holmes

Mycroft and Sherlock are brothers. They have never have had a very good relationship with each other when they were younger and they make jokes about each other and always have arguments. Mycroft has never approved of Sherlock's career and thinks he is capable of much more.

Jim Moriarty

Sherlock hated Jim. They first met when Jim was posing as gay boyfriend of Sherlock's hospital partner, Molly. But soon reveals his true identity and tries to kill John AND Sherlock but leaves because he got a new job offer. The next time they encounter each other is when Jim brakes into The bank of England, Pentaville prison and where they showcase the crown jewels just to show how clever he is but he is let go in court and starts ruining Sherlocks life which ultimately ends up with Moriarty killing himself so Sherlock has to kill himself to save his friends.

Molly Hooper

Molly is the lovesick hospital partner of Sherlock's. She is in love with him even though she realizes he has absolutely no feelings for her and he is always rude to her. Molly helped Sherlock fake his death to save his friends.

Irene Adler

Irene is seen to be the only person who understands Sherlock but does not challenge him even though they compete at an intellectual level. To this day they are still close friends
