Mycroft Yack is a yak and international detective in Sherlock Yack: The Movie. He is also the older brother of the title character, Sherlock Yack. He is a parody of Sir Arthur Conan Doyle's character, Mycroft Holmes.

Background
Since childhood, Mycroft was an incredibly gifted genius with excellent powers of deduction. Although, this belittled his little brother, Sherlock. Seeing that his brother was better than him, Sherlock made it his goal to surpass him. Living in Mycroft's shadow has led him to go to the monastery where he trained under Master Ball of Purity to hone his detective skills. Although, it wasn't enough to impress Mycroft. He believed it was a waste of his brother's time and potential. Both brothers were gifted with playing the violin, but Sherlock has no interest. After returning from the monastery, Sherlock became very interested in playing the bagpipes, which everybody (including Mycroft) knows he's very bad at it. Although, this inspired Mycroft to practice the bagpipes himself, and he was better at it than Sherlock.

Later in his life, Mycroft lost touch with Sherlock and started a career as an international detective. He would consult with Interpol, as well as other investigative agencies. He had recently take on an assignment to hunt down the mysterious international criminal, "Moriarty". But Moriarty seem so elusive, even to Mycroft's skills. So far, Mycroft was only able to capture the birdwing butterfly, Queen. She and her twin sister, Alexandra both work as Moriarty's henchgirls. Mycroft investigation has led to finding out that Moriarty has currently settled down in a zoo run by his brother.
