Bill Denbrough

The de facto leader of Shark Puppy as well as the Loser's Club, William "Bill" Denbrough is the oldest son of Zack and Sharon Denbrough, and the older brother of George Denbrough (deceased). He is canonically both an artist and a writer, and much of his songwriting is informed by his lingering guilt at his brother's death, his god complex, especially in regards to the other Losers, and self-image issues stemming from his stutter.

Musical Origins
"Bill is starting to get serious about creative writing and scribbles lines in the back of his notebooks, just things that form in his brain that he doesn't want to hold there; a few weeks later, he realizes most of it is about Georgie, even if not in so many words. He thinks and feels deeply, sometimes so deeply that he doesn't know where the thoughts and feelings are coming from. He finds comfort in gothic horror, comfort in the knowledge that terrible things can also be beautiful, and that he's not alone in his pain and grief. He feels the weight of responsibility on his shoulders, not knowing that he'll have the strength to protect his friends when they need him to. Because they will need him to. He's Big Bill, and that's his duty to them. It was his duty to Georgie. When it all becomes too much, he buys a new notebook, one especially for these thoughts and feelings, and he copies down everything he's already written, carefully turning them from scribbles in the margins of his homework to something much more sacred. He starts writing poetry, and he tells no one."
