The brand-new film's teaser trailer then confirms that the enemy in the film is Gatlantis. The film will depict "the struggle between the mysterious power Gatlantis and the Yamato crew who encounters it". Before the battleship Yamato returns to Earth, it receives a demand to surrender from a fleet that suddenly appears and calls itself Gatlantis. The Yamato warps to escape and arrives at a mysterious planet floating in an eerie alternate dimension.
Gatlantis also appeared in the 1978 film "Farewell Space Battleship Yamato" and other "Yamato" works before "Yamato 2199". However, the brand-new "Yamato 2199" film will have an original story.
