JapaneseSeveral months after the events of Sonic & Knuckles, an earthquake triggered by the Master Emerald Pillar disrupts the peace and dredges up a new island from the sea floor of the southern ocean. This mysterious new island morphs rapidly and drastically from a barren rock into a lush paradise. Naturally, this bizarre transformation piques the curiosity of self-proclaimed Emerald guardian Knuckles, who suspects that ruins from the lost echidna civilization surfaced with the island, and that something there is amplifying the power of the Master Emerald Pillar. The man in red heads off to investigate, but he's one step behind a certain egg-shaped scientist...
While investigating the mysterious island, Dr. Eggman discovers a tiny ring engraved with ancient writing, confirming that the island was indeed part of the lost civilization. More interestingly, he discovers ancient Special Rings on the island. The physical space occupied by these Rings has miraculously filled with crystallized Emerald energy, forming six powerful Chaos Rings. Information garnered from analysing these Chaos Rings can be used to summon the Master Emerald, so Eggman quickly erects a new fortress right on the mysterious island: the Newtrogic High Zone.
By the time Knuckles arrives on the scene, Eggman's plan is already in full swing. He has succeeded in crystallizing Ring energy to form artificial Dark Rings which he uses to power his robot army, including the newly rebuilt Metal Sonic. Furthermore, the nefarious Doc has invented a machine capable of freezing space-time, and has already used the device on would-be dissenters Mighty the Armadillo, Vector the Crocodile, and Charmy Bee. Espio the Chameleon is next in line for the freeze treatment, but is rescued in the nick of time by a fashionably late Knuckles, who has figured out that he can release one ally at a time using Ring Power. With Rings in hand, Knuckles and Espio infiltrate the Newtrogic High Zone to squash Eggman's latest ambition.

European & AmericanCarnival Island's in Chaos!
Tomorrow's the big opening day for Carnival Island, a huge amusement resort with the latest in high-tech rides and games. As guardian of the island, it's Knuckles' job to make sure nothing goes wrong before the grand event.
Unfortunately, the evil Dr. Robotnik has other plans. He needs fuel for his latest diabolical devices, and the Power Emerald that supplies electricity to the entire island fits the bill perfectly. His awful new invention, the Combi Confiner, should help him get rid of that annoying echidna and his friends.
When Knuckles returns from patrolling the far end of the island, he discovers that Dr. Robotnik has imprisoned all of his friends- Espio the Chameleon, Mighty the Armadillo, Vector the Crocodile and Charmy Bee. After he chases the Doctor off, Knuckles discovers that he can rescue one friend at a time by using Ring Power... only the power that sparks between the Rings holds the two partners together like a magical rubber band. Never held back for long, Knuckles finds that with a little teamwork, he can use the stretching and snapping action of the Ring Power to double-even triple- the partners' speed.
And they need all the speed they can get. As Dr. Robotnik drains the power from Carnival Island, everything on the island begins to break down! Robotnik must be stopped, or by tomorrow morning- the morning of Carnival Island's big opening day- the grand amusement park will lie in ruins!
