The Metropolis Zone boss is a large, multi-jointed robot that attacks with its arms. The arena is a small, enclosed space with a central platform.

Phases & Attacks:
- Arm Swing: The robot swings its arms in a wide arc, attempting to hit Sonic.
- Arm Extend: It can also extend its arms to reach Sonic on the central platform.
- Body Slam: Occasionally, it will jump and try to body slam the platform.
Strategy:
- Hit Robotnik's Head: Robotnik is vulnerable in the cockpit of the robot, which is its head.
- Dodge Arms: Jump over or duck under its swinging arms.
- Use Central Platform: The central platform is your primary vantage point for attacking and dodging.
This boss requires 8 hits. The challenge is finding the right timing to jump and hit Robotnik's head while avoiding its powerful arm attacks. Stay agile and use the small space to your advantage.
