Sonic the Hedgehog 3 & Knuckles
Seeking to stop the Death Egg as it relaunched from Angel Island, Sonic the Hedgehog and Tails made their way through Sky Sanctuary and eventually boarded the Death Egg. Knuckles himself later traveled to Sky Sanctuary to recover the Master Emerald, whose theft had been engineered by Dr. Julian Snively. There, he battled Mecha Sonic over the Emerald while Snively escaped.
