Toro Calican is the main antagonist of The Mandalorian episode "Chapter 5: The Gunslinger". Toro was a bounty hunter during the time of the New Republic. Looking to get into the Bounty Hunters' Guild, Calican took a job to find the assassin Fennec Shand on Tatooine.
Calican encountered the bounty hunter known as the Mandalorian in the Mos Eisley Cantina, seeking assistance with the job. They managed to capture Shand, who informed Calican that the Mandalorian was a target of the Guild. Calican "killed" Shand, and instead sought to turn in the Mandalorian. Returning to the Mandalorian's starship, the Razor Crest, Calican captured the child that the Mandalorian had rescued from the Guild. The Mandalorian killed Calican, leaving Tatooine with the child.
