Hopper1 (ホッパー1ワン, Hoppāwan) is an Insect Chemy based on a grasshopper and one of Houtaro Ichinose's main allies. It has a small body but a fiery heart. Hopper1 later transmutes itself into Crosshopper once all the Level Number 10 Chemies entrust their power to the Grasshopper Chemy. It would later be transmutated into the Hopper1 Malgam (Dark) (ホッパー1ワンマルガム (冥黒), Hoppā Wan Marugamu (Meikoku)) by Gigist's power.
