Floki
 
In the show Vikings my favorite character is Floki. His eccentricity and devotion to his gods make him all the more admirable. I am also a fan of Loki and both these characters are similar. In last season (3) His jealously caused him to act in a way he thought was pleasing to his gods. I saw the trailer for the next season of Vikings. It is a great show, on par with Game of Thrones.
