English story from US manual
Tomorrow's the big opening day for Carnival Island, a huge 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 imporsed 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 resuce one friend at a time by using Ring Power...only the power that sparks between the Rings hold 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!
Translated from Japanese manual
(This is the story listed in the Japanese manual for Chaotix. Translation by Windii.)
A certain floating island somewhere in the world. Several months have passed since the island grazed the sea surface due to an accident that happened on it.
However, there is a surge of activity deep in the seabed of the southern seas, which caused one island to suddenly appear out of it. This was the resulting aftermath of increased motion in the earth's crust stimulated by the power of the Master Emerald "pillar" on the floating island. Furthermore, the island was changing its appearance in a very short time at a tremendous speed.
The energy of the "pillar" transformed the island from a mere mass of rock into a green paradise.
"There's gotta be something on that island..."
Knuckle, the guardian of the Master Emerald "pillar", is questioning the island's sudden and ever-ongoing transformations.
Could it be that the remnants of the legendary civilization that was destroyed in an instant in the remote past due to the "power stones" going awry, lay dormant on that island?
"Something must be amplifying the power of the "pillar.""
With that thought and a sense of responsibility in mind, Knuckle headed straight to that island alone.
However, he was not the only one that thought so.
The very same thought had occurred to the highly infamous genius scientist, Dr. Eggman, who was already there investigating the island.
There, Eggman found a small ring engraved with ancient characters. And he learned that the very island was a part of the lost civilization.
In addition, he discovered a Super Ring identical to the one on the floating island. It was an ancient Special Ring that was used by the legendary civilization before it was lost.
"With this, I can reach the Master Emerald once again!"
Eggman was amazed by the discovery, but the "power stones" which the Special Ring was supposed to lead to were already transferred to the floating island by the gods that flew down from the sky.
However, the mysterious dimensional space created by the special ring was filled up with the "pillar" energy and turned into a ring-shaped crystal substance called the "Chaos Ring".
"If I uncover the secret of this Special Ring, I'll be able to summon the Master Emerald, not to mention find the secret of the rings that Sonic and his gang has!"
With that thought in mind, Eggman hurriedly builds a fortress on the island. The resort spot that was named "Newtrogic High Zone" was aswirl with Eggman's horrific plan.
And when Knuckle arrived near the island, it was already too late. Eggman had succeeded in crystallizing the energy. He named the artificial ring the Dark Ring. Furthermore, he was developing the Ring Power that produces space-time connections between rings.
"As long as I have this, they'll be able to do nothing. No one will be able to get in my way! This time, the whole world will be mine!"
Eggman was well on his way to realizing his ambitions.
