The Combi Catcher (コンビキャッチャー,Konbikyatchā?), also known as the Combi Confiner or Combi Machine, is a diabolical trap built by Dr. Robotnik to trap his enemies in Knuckles' Chaotix. It turns the victim into a statue-like figure.
The Combi Catcher serves to hold a member of the "Chaotix Crew" when selecting a character in Newtronic High Zone. In the Bonus Stages, hitting a "Combi Catcher" block will slow down the crane the next time it is used in the World Entrance, making the character selection easier. To start the machine, all the player has to do is press down when inside the "Catcher Box" (called the "Control Box" (コントロールボックス,"Control Box"?) in Japan), then press a direction to move the catcher claw and then a button to lower it.
