The character known as Insect is a general within Neos' army and claims to be their strongest fighter. She has the ability to control any type of insect and uses them for attacks. Her power proved effective, leading her to eliminate a substantial portion of Earth's military forces, establishing a foothold for Neos. During her battle with Iczer-3, Insect's armor made from rhinoceros beetle shells was too tough for Iczer-3's swords to penetrate. Eventually, she revealed her ultimate weapon: the ability to transform into a giant insect larger than a five-story building. This forced Iczer-3 to call upon Iczer-Robo for aid. Despite this, Insect was ultimately killed in combat by Iczer-3, making her the only one of Neos' four generals defeated in battle.
