The final boss, the Death Egg Robot, is a massive, imposing machine. Like Silver Sonic, there are no rings in this fight. You must defeat it with your remaining lives.

Phases & Attacks:
- Jump & Crush: The robot jumps high and attempts to crush Sonic.
- Arm Punch: It extends its arm to punch Sonic.
Strategy:
- Hit Robot's Chest: The robot is only vulnerable when its arm is fully extended and its chest opens slightly. Jump and hit its chest.
- Dodge Jumps: Move quickly to avoid being crushed by its jumps.
- Dodge Punches: Stay out of the way of its extended arm.
- Patience & Precision: This is a long fight that requires perfect dodging and precise attacks.
This boss requires 12 hits. If you have Super Sonic, you can fly into its chest repeatedly to defeat it very quickly. Without Super Sonic, this is one of the most challenging boss fights in the game, demanding absolute focus and ring management from previous zones.
