Hunter × Hunter: Phantom Rouge
"Hunter × Hunter" creator Yoshihiro Togashi wrote the two-part manga to act as a prequel to the film. A collected version of the story, referred to as "Volume 0" of the series, was given to the first million moviegoers. A light novel adaptation of the film was released by Shueisha on January 15, 2013.
Maverick Hunter
"Maverick Hunter" was in development by Armature Studio and was to be published by Capcom for the "Mega Man X" series. The collaboration was established by Keiji Inafune, who had previously worked on the Mega Man series as an artist and producer. He had since rose in the ranks at Capcom to become a producer. The goal was to attract a new audience to the "Mega Man" series. Its development would have been overseen by former Capcom producer Ben Judd. The redesign for the Mega Man character was to be done by Adi Granov (the concept artist responsible for the Iron Man redesign found in the 2008 film of the same name). An initial concept design showed X with a red glowing 'X' on his face.
