The Chain Machine is an enemy in Crisis Core -Final Fantasy VII-.
This robot machine is the aggressive type, as it will continuously tail Zack during battle. But it gives Zack advantages; it will be easy to get behind it and land some critical hits with Command Materia. Using Jump avoids the constant attacks, while dealing damage. It can inflict Stun frequently with its Spinning Saw and Chainsaw attacks, as well as Silence with Silence Gas and Poison with Poison Gas.
