The Masked Monster discovers that the key for dealing with the Gorengers both involved taking care of their teamwork and destroying Variblune: to deal with both, he creates a scheme where he lures two of the Gorengers, Peggy and Asuka, to a location where he abducts Momorenger and hypnotizes her into hating her Gorengers teammates as well as planting a bomb on her for destroying Variblune. When she finally is reunited with the other Gorengers, she throws down the bomb within the airship, it damages the engine but the male Gorengers escape while Peggy continues to have problems in trying to transform into Momorenger.
