The 2013 anime special, which also features characters from Toriko, will air during Toonami next month.
The heroes of the manga anthology Shonen Jump—Luffy from One Piece, Deku from My Hero Academia, Goku from Dragon Ball Z, Naruto from Naruto, Ichigo from Bleach, etc., etc.—aren’t exactly strangers to each other, having appeared in countless video games and promotions together. But strangely, the manga anthology’s two biggest stars (that would be Luffy and Goku) have only met in animated form once, back in 2013, in a special that never made it to America. Well, not until next month, at least.
The crossover is really an episode of One Piece preceded by an episode of Toriko, another Shonen Jump manga/anime that was popular at the time, and which was also part of it.
