Years prior to the present day, Sonic the Hedgehog made his way to this Zone on his own, having decided to leave behind his friends Miles "Tails" Prower, Knuckles the Echidna, and Amy Rose so that he could cover more ground at his own pace. Sonic would nearly admit defeat when he came across a wall overflowing with lava that was too high for him to scale alone. Fortunately, he was found by his friends and worked together with them to bypass the wall and enter the temple Dr. Eggman was hiding in. Sonic and Knuckles confronted the doctor's chef-inspired mech while Amy and Tails, fazed by the temperature, took a break.
Unfortunately, after Sonic and Knuckles destroyed the mech and obtained the next Ancient Gear, Metal Sonic suddenly ambushed the heroes, stealing the other five Ancient Gears and kidnapping Amy in the process, too. After forming a plan to find Metal Sonic and Eggman, Sonic, Tails, and Knuckles departed the Zone.
