William

"I is William. You, Fenn, is my friend."

"William" was the name given to a male giant who originally lived in the North, before being saved by Ned Frost and joining his army. He considers himself "the Last Good Giant".

Physical Appearance
William stood at fifteen feet tall, which was small for his species. Nonetheless, he was still remarkably large by human standards. He is fair-skinned, with thick brown hair, brown eyes, and a clean-shaven chin. He has a voice that sounded like "war drums" and a laugh that shook the ground due to its deepness.

Personality
William generally seems to have a happy demeanor, overjoyed by basic things like presenting Ned with firewood, hearing the echo of his own voice in a well, or greeting Finn's steed Winterbolt. He is deeply loyal to Ned and the Wintermen, who treated him very well. Despite his large size and strength, William is a gentle soul who is terrified by violence - even violence done by himself, as he often cowers in fear instead of fighting back against foes who are actually smaller than he is (something Walder chastises him for). When he kills Squealer, he expresses total horror at what he had done. Even so, his loyalty to the Wintermen is so great that he continues to follow them through great dangers, even though his life was endangered.

Despite being a giant, William is able to speak quite well. However, he has difficulty pronouncing things, and thus considers Finn as "Fenn" and Ned Frost "Nuh Froz".
