The Vacuum Banki is a dumb and bumbling Savage Sky Barbaric Machine Beast. Kitaneidas wanted to target the Go-On Wings, but Vacuum was unsuccessful in capturing Go-On Gold. Vacuum Banki has the power to suck things into his vacuum bag. He was indeed successfully in capturing Go-On Silver and held her hostage, demanding Gold for his henshin items. He refused but Go-On Red arrive and obliged to give him his items, which he sucked into his bag and retrieved after Gold blasted him. He is the first Banki to be destroyed by Engine-Oh Jetripter.
