Byle was a young stoat Captain in the Blue Hordes. Despite his position, he was quite a well-spirited captain and eager to impress Trunn. However, because of his inexperience, many Blue Horde vermin disrespected his authority. Whilst on a foraging trip, he was ambushed by the Bark Crew. Trunn later used the stoat as a shield while he was passing by the windows to divert some squirrels, who shot Byle to death.
