Amazing Captain Rainbow

On the surface, Nick seems to be just like any other ordinary guy living in Mameruka, but in reality he is anything but! He is able to transform into the yo-yo wielding superhero Captain Rainbow, but as trends changed and newer heroes appeared, he was forgotten about. In a bid to regain his popularity, Nick travels to Mimin Island, a place where wishes are said to come true. While there, he meets a variety of lesser-known Nintendo characters, each with their own hopes and dreams that Nick must now help them achieve!

Amazing Captain Rainbow was a doujinshi created by Rui Nakagawa, and was based on the Japan exclusive Wii game "Captain Rainbow" developed by Skip Ltd. and published by Nintendo. Amazing Captain Rainbow went on indefinite hiatus midway through the second volume.
