|Game: Sonic the Hedgehog 2 (8-bit)|
|Level: Sky High Zone|
|Hits to defeat: 6 (excluding Mecha Chicks)|
Before Sonic can fight the boss itself, he must fight two waves of Mecha Chicks, at which point he drops through the clouds to smash the cybernetic eggs which create them. Spin rolling works well in this part of the boss fight, and do note that the eggs will still produce the bird badniks while Sonic is attacking them.
Only when its 'nest' has been destroyed does the boss rear its chrome-plated head (on an extremely extendable neck). It proceeds to fire energy balls in Sonic's direction, which possess a limited degree of homing. Six spin attacks will finish it off, and if Sonic is fast enough the Gachou Mecha can be defeated without ever giving it a chance to attack.
