Robotnik (Green Hill Zone Boss)

From Sonic Retro

The Green Hill Zone Boss is the first boss encountered in Sonic the Hedgehog. Today, it remains one of the most famous boss fights in video game history, with its ball-and-chain recreated in other Sonic games and parodied by other series. The checkered ball appears to be leftover art from a pre-release of the game, which included a rolling ball for Sonic to interact with. A pre-release version of the boss itself is different in that it shows a red ball with a spinning diamond around it.

Defeat Strategy

The attack pattern of this boss is quite predictable. Dr. Robotnik will swing the checkered ball back and forth, trying to hurt you with it. When he swings the ball toward you, the safest place to be is under one of the two platforms, where he cannot harm you.

First off, get on one of the platforms. When Robotnik swings the checkered ball in the opposite direction, jump and hit him once. When he swings the ball in your direction, quickly get under the platform, and back onto it once it's safe. Repeat the process from here. You'll need to hit him 8 times before he's destroyed.

There is also an alternative, and quicker way of defeating Robotnik. You can attack Robotnik at any time, due to the platforms. These are high enough so that you can simply attack. First, when you hear the music start, quickly get on the right platform and attack Robotnik as many times as possible during the fall. Now, stay on this platform as he'll strike to the left first. Attack quickly and you'll get probably 2 hits. Do the above until defeated.
