A supergroup is a group of people who have superpowers and play music together. Common supergroup bands include the Justice League (they're R&B and Gospel), Fantastic Four (Rap/Hip-Hop), and Scooby Doo (Mystery-rock). Supergroups are commonly from Pittsburg, Oklahoma, but one of them were from Canada and were shot when trying to cross the United States's border, the marshals thinking they were Mexicans, but instead, they were Canadians, but they were just like "Oh well" and started shooting random people after traveling to Vancouver.
