Sonic the Hedgehog & Knuckles
Seeking to use the Master Emerald as an energy source to fuel his Death Egg, Dr. Eggman stole the gem from the Hidden Palace Zone during a battle between Sonic and Knuckles. Putting their differences aside, Sonic, Knuckles and Tails went in hot pursuit after Eggman from the Hidden Palace Zone. Knuckles later passed through Hidden Palace Zone during his hunt for a Eggbot controlled by Snively.
