Emmy Kano arrives with the rest of the Futurians aboard MOTHER, having travelled from the 23rd Century to Japan. She witnesses the removal of Godzilla from the timeline, remains with the Futurians until she meets Kenichiro Terasawa. The Futurian then plans to defect from her superiors. M11 is sent to pursue her, but she persuades him to follow their plan. In the midst of the new Godzilla's battle with King Ghidorah, Emmy, Terasawa and M11 raid MOTHER, disabling the communicator to Ghidorah. The Futurians try to escape, but using a teleporter, Emmy moves the spaceship in front of Godzilla, who destroys it shortly after the raiders leave. Everyone aboard MOTHER died instantly, saving the world from the Futurian threat. Emmy then uses KIDS to travel back to the future with M11, and she then works on gaining the components to create Mecha-King Ghidorah. Piloting the Cyborg to defend Japan, Emmy travels back to the present with M11, now incorporated into the machine components. The battle rages, and Godzilla destroys Ghidorah's wings, causing the cyborg to fall towards the ocean. At the last minute, Emmy escapes aboard KIDS. It is first thought that M11's brain was destroyed in the wreck of King Ghidorah, but as she leaves to go back to the future with KIDS, it is revealed that she saved M11 before escaping. She then tells Terasawa that she is a descendant of him, and that she hopes to see him again in the near future, before heading home.
