A 30 minute Battle of Gods discussion panel was held at Jump Festa 2013; on the Jump Super Stage, on December 22, 2012. Along with the voice actors Masako Nozawa, Mayumi Tanaka, Toshio Furukawa, the film director Masahiro Hosoda, editor-in-chief Akio Iyoku, and Toei Animation producer Gyarmath Bogdan took part at the discussion which was overseen by former YBS TV announcer Mariko Nakagomi.
Masako Nozawa read out a letter from Akira Toriyama saying he tried hard as personal revenge for the live-action film which was bad, and that he and the scriptwriters reworked the story a bunch of times. The character images Toriyama drew for the movie were displayed; he drew Android 18 with purple hair instead of blonde and he had to have this pointed out to him.
