A lone operative targeted Dr. Koizumi in order to keep their race's existence as a secret and killed him through a fake suicide, later pinning the blame to Ueno. While targeting Koizumi's daughter, Chidori, Go managed to gather the evidences of Koizumi's murder and free Ueno. Jack thwarted his attempt to kill Chidori and finally killed the enlarged creature with Ultra Spark. With Koizumi's notes, MAT put them into use for their war against the rest of the Kingbockle race.
