Zordon, and Oracle sends Sonic, and The Searchers sets out on several quests: Sonic visits Tails' workshop and finds that Tails has already gained the Green Chaos Emerald, so they use that Emerald to find the cyan Chaos Emerald; Knuckles tries to find the pieces of the shattered Master Emerald (which was shattered by the Chaos creature when Knuckles was asleep); and Big and Chris to find Big's friend Froggy. Meanwhile, Amy finds a Flickie bird with a Chaos Emerald pendant and calls it Lily. After Sonic and Tails find the Cyan Chaos Emerald, Chaos undergoes another transformation after absorbing the Green and Cyan Emeralds, and Eggman unveils his new Egg Carrier. Sonic and Tails attack in the X-Tornado, but are overcome (Sonic survives; Tails injures his left arm and head), while Amy and Lily are abducted by The Villains.
This Marks the Debut of Chaos 0
