Kamen Rider × Super Sentai: Super Hero Taisen
When the Den-Liner took Joe Gibken and Don Dogoier with Daiki Kaito and Hina Izumito Winter 1976, they met Baseball Mask, who was quickly destroyed by Akarenger (later revealed to be Captain Marvelous in disguise).
- Considering he has a baseball for a head and his crime life is centered around baseball, he could be an evil take on the New York Mets' mascot, Mr. Met.
- His appearance in Kamen Rider × Super Sentai: Super Hero Taisen sees him in Winter 1976, the days of Himitsu Sentai Gorenger, making Baseball Mask the only monster in the movie not to be a part of the present day Shocker-Zangyack Alliance.
