Yanki J is a character played by Justin Carmical (Jew Wario). He's a gangster type character with a baseball bat, and a love of the Kunio Kun games. The name Yanki is a direct reference to the Japanese term "Yankii" that describes delinquent, troublemaking students who are usually involved in school related gangs. He first appeared in the Ike Ike! Nekketsu Hockey Bu review and reviewed the game alongside Jew Wario. His second appearance was in the Nekketsu! Street Basket review, where he took over the show by tying up Jew Wario and performed the review himself.
