Kidou Senshi vs Densetsu Kyojin: Gyakushuu no Gigantis

Synopsis

In this story, set in Universal Century 0090, the Federation sends Amuro Ray to recruit Judau Ashta to help deal with a group of Zeon remnants. While this seems routine, the Zeons have uncovered what they call the "Giant God", namely the Ideon (which is never actually called Gigantis nor Ideon within the story). While investigating, Judau learns that the Zeons are planning on using Mineva Lao Zabi's Newtype powers to awaken the Giant God and get their revenge. This manga is non-canon.
