Repairing the Death Egg[]

Sonic 3 and Knuckles History

Knuckles attempts to stop Dr. Eggman from stealing the Master Emerald.

After his defeat at the hands of Sonic and Tails in the skies above Launch Base Zone, Dr. Eggman's Death Egg crash landed once again on Angel Island, this time on top of the volcanic crater, Lava Reef Zone. He eventually obtained the Master Emerald from the Hidden Palace Zone during a battle between Sonic and Knuckles and used it as an energy source to fuel his Death Egg. His repaired flying fortress then took off into the sky with Sonic, Tails, and Knuckles in pursuit. (VG: S3aK, SU: #64)

Knuckles later passed through Hidden Palace Zone to reach Sky Sanctuary Zone, where an Eggrobo (piloted by Snively) fled to after multiple encounters on the island. (VG: S3aK, SSD: #12)

Background Information[]

  • The Hidden Palace Zone is named after two locations of the same name. The first was a cavernous area meant to be put into Sonic the Hedgehog 2. To this day, many video game enthusiasts have tried to figure out what purpose the area held, especially with the mysterious Master Emerald-like rock in the Zone. The second location was the third-to-last stage (not counting Doomsday Zone) in Sonic and Knuckles. Here, the Master Emerald and the Super Emeralds resided.
