The Scavenger Probes were special robotic probes that can be used to capture a specific single target and bring it back to where they were sent from. Minimus used to them to try and capture Atomic Betty when Maximus was sick, but due to not giving a specific target and only telling the probes to capture "That girl, Betty", the probes captured many different Betty's from all over the galaxy, along with Atomic Betty.
