It's Santa Claus's nephew Larry. He was neglected at a young age, and laughed at. He grew up poor, and was mocked. He was an aspiring trumpet player, and wanted to join the elf marching band. His dreams were put down when his uncle forced him to work in his sweatshop in the north pole. To put him out of his misery, you must use an enchanted battle ax made of pure gold...
Or just throw a rock at him

Who is this evil warrior, and how can he be slain?
