When Ann began to lose energy, Alan sent Insectia to drain energy from Darien for her, but she refused to listen to him and jumped on his head. Without attacking Darien at all, Insectia attacked a school and drained energy from students there. She also came to steal energy from Miss Haruna and her boyfriend, Robert, and was scolded by Alan for her disobedience. Instead of attacking Miss Haruna and Robert, Insectia drained energy from ducks. The Sailor Scouts (minus Sailor Moon, who was in detention with Ann) attacked her but she gained the advantage. Serena transformed into Sailor Moon to fight Insectia, but was unable to use Moon Scepter Elimination against her, as Ann had drained some of her energy. When the Moonlight Knight told her to believe she had the energy to defeat Insectia, Sailor Moon destroyed her with her scepter.
