Dyson (portrayed by Kris Holden-Ried) is one of the main characters from the Canadian fantasy series Lost Girl. He is a Light Fae Wolf-Shifter and serves secretly as Trick's 'lieutenant'. Dyson works in the human world as a homicide police detective in the 39th Division Homicide Squad. Though at first glance he appears middle-aged, he is actually 1,500 years old. He spent centuries in Ireland serving the Laignach Faelad wolf-shifter King of Ailech with his best friend, Stefan. In terms of shifter tradition, warriors like Dyson fearlessly and unquestioningly believed in total loyalty to their King. This changed when the King betrayed his wolf pack and had his best friend, Stefan, killed to take his wife, Ciara, for himself. After this, Dyson left his pack for good, becoming, in effect, a lone wolf. Like all Wolf-Shifters, Dyson can shift completely into a wolf or partially. When he part-shifts, the nature of his eyes change and his teeth become lupine with fangs. In terms of personality, Dyson is often short tempered and easily aggravated. However he is also fearlessly and unquestioningly loyal to his friends and displays a certain respect for rules and the law. However, he shows willingness to bend rules in order to serve his friends, particularly Bo and Kenzi.
