Is Floki based on a real person?

Could you please clarify for me? Is the character Floki, as mentioned in the context, inspired by an actual person from history or mythology? Or is he a figment of the creator's imagination, a completely fictional character with no real-world counterpart? If he's based on a real figure, could you provide some brief details about that person and the similarities between them? Conversely, if he's entirely fictional, what are the creative inspirations behind his creation? Thank you for your clarification.
