Return of Ultraman
Alien Cygnus-61 was orginally a peaceful alien who was kidnapped by Alien Messie to do his bidding. She is first seen watching over the fight with Robonez and Ultraman Jack. After his defeat, the alien then blew up a plane by sneaking in a bomb in the shape of a pen,this was the plane that Goh originally booked. She then takes the name of Erika Shiratori and makes friends with some of the kids at school (with some the kids liking her a lot). She then gave it to Jiro, who brought it to Hideki Goh. She was soon found and her control band was shot off. Out of Messie's control temporaly she told a MAT Doctor that Alien Messie killed her dad and forcefully controlled. However her and a MAT doctor where controlled. They then ambushed Hideki Go before Alien Messie grew big. After the aliens defeated, both are freed from the aliens control and she then returns back to her planet, thanking everyone for their kindness.
- Alien Cygnus-61 is one of the few aliens to not have a subtitle, possibly because her intentions were not malicious.
