TOKYO — As a tie-in to “Big Hero 6,” the first-ever Disney-Marvel animated feature, Disney is collaborating with the release of a manga in Japan based on the pic’s story.

Called “Baymax” — the pic’s Japanese title — the manga will be serialized in Magazine Special monthly comic starting on Aug. 20.

A prequel, “Episode 0,” will appear in Weekly Shonen Magazine on Aug. 6.

Both comics are the work of Haruki Ueno, who is also responsible for “Phi Brain: Saigo no Puzzle” (“The Last Puzzle”), a popular mystery manga that debuted in Magazine Special.

The comic features the title robot, Baymax, and its boy companion, Hiro, whose adventures unfold in the fictional city of San Fransokyo.

The Disney pic will be released on Nov. 7 in the U.S. and on Dec. 20 in Japan.

Disney has not yet announced how long the comic will run beyond those dates or whether a TV toon — the usual progression for a popular manga in Japan — is in the works.
