American football has long been a spiritual dish for Americans along with basketball, and baseball. It is understandable that DC Comics brings this sport into its cinematic or comic universe. In this article I will summarize some of the teams in the DC cinema and comic universe and the fun fact that I found. Note that the following teams are not sure to play together in a universe or a tournament.
Gotham Rouges: Appears in The Dark Knight Rises directed by Christopher Nolan. This shirt color is probably inspired by the Pittsburgh Steelers currently playing in the American Professional League (NFL). Fun fact: the stadium that Gotham Rouges plays in The Dark Knight Rises is the home of Pittsburgh Steelers, Heinz Field.
Rapid City Monuments: The team competes with Gotham Rouges in The Dark Knight Rises. Fun fact: The 19th baseballs player, Ravenstahl, is a former American football player in real life.
Gotham Knights: First appeared in the Fear of Victory episode of Batman TV series (1992), and later in the Justice League TV series “Secret”. The team uniform is gray shirt and red pants.
Boston Colonials: Team battle with Gotham Knights in Fear of Victory.
Blüdhaven Brawlers: Appeared in Nightwing (volume 2) # 26, not much is known about this team.
Central City Cougars
Steel City Tigers: appears in the Teen Titans Series on Cartoon Network. In the episode, Raven is teleported to the field where Steel City Tigers are playing and is crushed: V
Metropolis Sharks: Appears in Smallville “Reaper”. This team is owned by LuthorCorp.
In addition, some of the real-life teams that are competing in the US NFL professional league are also in comics like New England Patriots, Baltimore Ravens, Chicago Bears, Indianapolis Colts, Oakland Raiders, Pittsburgh Steelers or St. Louis Rams (now Los Angeles Rams).
