Lamprey Mask was part of an squadron who attacked an EAGLE warship, setting up upon it a powerful bomb that not merely would make the ship explode but cause a massive explosion to attack a large area when it went off. When Shinmei and Oiwa discover that the bomb was set there and with lack of their own knowledge, the Gorengers attempt to transport Peggy to the site; but Lamprey Mask attacks Momorenger en-route, hurting her and making it harder for the Gorengers to defuse the bomb as the time continued to count down.
