Protagonists
- Quentin MacLeod: The titular character of the series. Raised by the Dundee clan, he was killed by Arak and subsequently resurrected as an Immortal, when Kortan sought to capture the Dundee. He usually fights with the sword that belonged to Connor MacLeod but also carries a boomerang he is quite skilled with.
- Don Vincente Marino RamÃrez: The Jettator tasked with guiding Quentin and making sure the other Jettators keep the oath. He trains Quentin in the art of combat as well as philosophy and some history. Many episodes feature flashbacks of his life.
- Clyde of the Dundee: Quentin's adoptive younger sister, though raised as his blood relative. She often ends up in danger during missions but on occasion serves as a distraction.
- Sarah MacLeod: Descendant of Duncan MacLeod, via his sister. She is a cousin of Quentin. Sarah was seen in several episodes, while Quentin is traveling. With fiery red hair and an equally fiery temper, she once aids her cousin before and after a battle.
- Gaul: Clyde's pet Gran, a hybrid of ape and canine. Like all Grans, Gaul is highly intelligent and is very protective of both Clyde and Quentin. His animal sense sometimes helps Quentin in dangerous situations.
