Kidou Senshi Gundam: The Origin - Movie Edition

In the year 0068 of the Universal Century, Casval Rem Deikun's life is thrown into chaotic disarray after the assassination of his father, a prolific figure in the crusade towards civil rights for people who live away from the Earth's surface. Casval and his sister Artesia receive aid from soldiers who were loyal to their father, and the siblings are whisked away from their home, separated, and thrown into a twisted fate that sees them come into their own as soldiers and adults. Years before stealing the name Char Aznable or his "Red Comet" moniker, Casval must contend with the rise of a militarized version of his father's ideology and his own vengeful nature as intergalactic war molds him into a legendary mobile suit pilot.
