Seasons of Chaos
Seeking the Chaos Emeralds to conquer the world, Heavy King sent out Metal Sonic and Metal Knuckles to retrieve them. The blue Chaos Emerald, which had been found by a Pocky on Angel Island and handed over to Knuckles, was soon after claimed by Metal Knuckles follow a skirmish with Knuckles, and brought to Heavy King. Not long after, the green Chaos Emerald was found by Sonic, Tails and Amy in Spring Valley Zone. Before Sonic could take the green Chaos Emerald however, Metal Sonic swiped it in front of him and ultimately escaped with it, which he then brought to Heavy King.
The yellow Chaos Emerald, which was lying on a pillar behind a waterfall in Summer Falls Zone, was soon found by Sonic, Tails, Knuckles, Fang, Bark and Bean, the three latter having been hired by Eggman to find the Chaos Emeralds before Heavy King. During the ensuing fight between the trios, Fang grabbed the yellow Chaos Emerald, only to lose it to Tails when Tails tampered with his Marvelous Queen. However, Tails dropped the yellow Chaos Emerald when Fang retaliated. Though it got picked up by Sonic, Fang shot it out of Sonic's hands, leaving it to roll over the cliff of a waterfall and land on Mighty's head, who claimed it. Meanwhile. the red Chaos Emerald was found by Metal Knuckles while the turquoise Chaos Emerald was found by Metal Sonic. Arriving in Autumn Forest Zone on the way to Heavy King, Metal Sonic found and claimed the white Chaos Emerald as well. Meanwhile, the purple Chaos Emerald was found by Mighty, Ray and Amy, only for Fang's gang to arrive and fight them for it. In the end though, Metal Knuckles came by and stole the purple Chaos Emerald.
Ultimately, all seven Chaos Emeralds were brought to Heavy King's base in Winter Caverns Zone. Having inserted them into a platform, Heavy King harnessed the Chaos Emeralds' power and used it as energy attacks against Sonic and his assembled allies when they came to stop him. However, while Sonic distracted Heavy King, the others took back the Chaos Emeralds one by one. After then defeating Heavy King, the heroes fled with the Chaos Emeralds, which they decided to share between them to keep Eggman from easily getting to them; Fang's gang took the purple Chaos Emerald, hoping to trade it in for a hefty reward; Knuckles took the green Chaos Emerald back to Angel Island; Mighty and Ray took the turquoise and white Chaos Emeralds with them; Tails took possession of the yellow Chaos Emerald to hide it somewhere; Amy got the red Chaos Emerald to hide; and Sonic took the blue Chaos Emerald away to hide it elsewhere.
