(This chart shows how much Doctor Eggman values his minions, with top being the most loved and bottom being the least loved, by Eggman anyway)
Metal Sonic: Captain of the Badniks and Eggman's favourite son, greatest creation and favourite robot.
Sage: Eggman's personal hacker, only daughter, favourite daughter and favourite AI.
Dreamcaster: Second in command of the Badniks (if Metal is ever having a jealously episode, Dreamcaster takes over) and the robots in charge of kidnapping and hypnotising Mobians into becoming robotised.
Orbot: One of the lair's two caretakers, being a middle child, he takes most of the hits from his creator, he's also a bit smarter than his twin.
Cubot: One of the lair's two caretakers, being a middle child, and a lot less smarter than the other robots who work for Eggman including his twin, he takes most of the hits from his creator.
All other Badniks: Underlings for Eggman, whom serve no real significance.
Robo Rabbit: The only robot who rebelled against Eggman and joined Team Sonic, she is disgraced by all of the doctor's creations and even the doctor himself.
