Bowser Jr. (known as Koopa Jr. (クッパJr., Kuppa Junia) in Japan) is a fictional character who appears in Nintendo's Mario franchise as an antagonist. He is the son of the series' main antagonist, Bowser. Since his debut in Super Mario Sunshine in 2002, Bowser Jr. has been a recurring character in the Mario series and has been made playable in several spin-offs, such as Mario Superstar Baseball, Mario Strikers Charged, Super Smash Bros. for Nintendo 3DS and Wii U, and Super Smash Bros.
