Mako is a firebender from a multicultural family who grew up on the streets of Republic City as an orphan with his younger brother, Bolin. Mako always wore his signature red scarf that was once his father's, who was murdered along with his mother when he was a boy. He formed a pro-bending team with his brother and Hasook and aspired for his new career to bring him fame and fortune. His aspirations changed, however, when he met Avatar Korra, who joined the team to replace Hasook and became a loyal friend. Mako, with the help of his teammates, was able to lead the team to second place in the championship. After the tournament's conclusion, Mako joined Korra in her efforts to stop the Equalists. In the following months, Mako joined the Republic City Police Force, where he steadily rose up from being a beat cop to a detective. He joined his friends in an effort to stop Unalaq and Vaatu from merging. A few weeks after Harmonic Convergence, he rejoined Team Avatar in their search for new airbenders. However, they stopped when the Red Lotus attempted to kidnap Korra in Zaofu, instead working to bring down the anarchist organization. After taking down the Red Lotus, Mako returned to his work as a police officer and was later appointed as Prince Wu's bodyguard, a position he continued in after the latter's coronation as Earth King. Following Kuvira's failed invasion, Mako returned to his job as detective.
