The Boston Colonials were a football team.
Hailing from Boston, the Colonials were bitter rivals to the Gotham Knights. Scarecrow once tried to rig the game by poisoning Knights' quarterback Mitch Nole. On another occasion, the Secret Society hijacked the pitch during the half time interval.
Despite being from an actual city, the Colonials don't exist as a football team. The only team using the name is a vintage base ball team.
