William was born on October 4, 2001. He has a big rivalry with his father, sister, and sometimes his cousin and mother, but mostly his father due to him being his arch-nemesis. William is a stupid, rude, crude, moronic, short-tempered, stubborn, selfish, reckless, naive, remorseless, egotistical, and argumentative person who spends a lot of time playing on his Xbox and is usually shown destroying some of Lucy's objects, which bothers his family members (mostly his father Bill,)
