America

USA loves Canada like a brother, as they almost never argue. They text each other frequently, maybe several times a week, unlike Britain. America doesn't talk to him very often, finding his father too prim, serious, and boring. They don't really fight, either, but America is irritated by Britain constantly correcting him or criticizing his behavior, because he believes he's already an independent adult and wants to be independent without his father's dictates.
Father - Britain, Great Britain
Younger brother - Canada

Full name: United States of America (USA)
Full name (human only known in Great Britain): William Smith Ankled
Appearance: His face is the colors of the American flag. He has blue eyes and white hair with red streaks and blue bangs on the right side of his face. He is 186 cm tall, with a slightly athletic build, a toned stomach, and a slight, yet discreet, six-pack. He usually wears jeans and a tank top or T-shirt, and wears a black suit and white shirt to business meetings.
Personality: Quite narcissistic, vain, annoying, and joking. He can be serious at times. Usually, this joker's facade is used to hide vulnerability and insecurity. He loves and supports the LGBT community, which doesn't sit well with his British father. So, he sometimes indulges in junk food.
He has a normal relationship with his father (Britain). But Britain is often angry with America because America calls Britain "England." America also has a younger brother, Canada; there's a slight age difference between them.
