The Egg Beetle Security System was implemented in Eggman's Hidden Base "Egg Quarters" in Sonic Adventure 2 and Sonic Adventure 2 Battle. This machine was an ingenious innovation, that is completely incapable of being destroyed or harmed, which Eggman had created to stop anyone from infiltrating the base, the only problem is its one and only flaw, it cannot see in the dark. If Rouge were to hide in the shadows she will be protected from any detection of this robot. There are two Egg Beetles patrolling the Egg Quarters at all times.


  • If Rouge attacks the Egg Beetle it will immediately attack without any warning, even if she was in a shadow.
  • The Egg Beetle has to charge for every single attack, so after it has attacked Rouge it will be unable to attack again no matter what for at least 10 seconds when it is fully charged again.
  • Oddly, the Egg Beetle Security System was only implemented in Rouge's level "Egg Quarters" and not in the Knuckles' level "Death Chamber" which was also inside the Hidden Base.
  • In the Dreamcast Version, when the Egg Beetle enters an area, the screen will pulse green faster and faster the closer it gets to Rouge then slower when it moves away, but in the Gamecube Version, the screen simply flashes green until it is gone.
