Set on some kind of orbital platform high above Sonic's world, the Zone is much like the original Death Egg Zone in that it is composed of a series of boss fights. Dr. Eggman returns with some of his most familiar boss machines:
- Egg Mobile: Hammer Ball-shiyou (エッグモービル・ハンマーボール仕様), also known as Egg Mobile-H. A return of the Green Hill Zone boss from Sonic the Hedgehog (16-bit).
- Egg Mobile: Drill Machine-shiyou (エッグモービル・ドリルマシン仕様), also known as Egg Mobile-D. A return of the Drill Eggman boss from Emerald Hill Zone from Sonic the Hedgehog 2 (16-bit).
- A new boss as the third opponent: the Egg X.
The first two bosses are weaker than their original versions, requiring only four hits to destroy, regardless of the difficulty mode. The Egg X is somewhat more challenging. By having all the seven Chaos Emeralds and then beating this level as Sonic, you can unlock true last boss in The Moon Zone.
