Floki is a Jomsviking commander who was one of the principal Viking commanders under Sweyn Forkbeard during the invasion of England and subsequently under Canute. He contracted Askeladd to assassinate his former comrade Thors.
Floki has fair hair which unlike that of other Vikings is kept trimmed to medium length. His beard is also trimmed to form a rectangle, giving his face a square-like appearance. He has a large scar running down the right side of his face reaching down to his lip. He dresses in the same attire as his Jomsviking crew, although after his initial appearance when he was wearing a helmet, has since been depicted without it.
Floki was only shown briefly in combat when he crossed swords with Askeladd after the latter's assassination of Sweyn Forkbeard. However as only exceptional members of the Jomsvikings are made commanders, his combat abilities are presumably formidable.
He has been employed by Sigvaldi and Sweyn as an emissary with delicate tasks such as convincing Thors to return to the fold and attempting to convince Thorkell to renounce his allegiance to the English, indicating that he has a degree of diplomatic skill.
Floki served alongside Thorkell and Thors when the latter was still a Jomsviking and as a fellow commander is well known by them.
