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!

A floating island somewhere in the world. It has been several months since an incident caused this island to graze the surface of the ocean.
However, an upheaval occurred deep in the south sea, and an island appeared out of nowhere. It was a product of tectonic movement, caused by the power of the Master Emerald "pillar" on the floating island. Moreover, the island was changing its appearance at a very fast pace in just a short period of time.
The energy of the "pillar" was transforming the island from a mere rocky mass into a green paradise.
"There's something on that island..."
Knuckles, the guardian of the Master Emerald Pillar, wonders about the rapid changes on the island that continue uninterrupted.
Are there vestiges of a legendary civilization lying dormant on the island, which disappeared in an instant due to the runaway "power stone" in the distant past?
"Something must be amplifying the power of the 'pillar.'"
With that thought and with a sense of responsibility as a guardian, Knuckles went to the island alone.
However, he wasn't the only one who thought so.
Dr. Eggman, the infamous genius scientist, was also one of them, and had already gone to the island to investigate.
There, Eggman discovered a small ring with ancient writing carved on it. It turned out that the island had been indeed part of a lost civilization.
He also discovers a super ring that looks exactly like the one on the floating island. It was an ancient special ring that was used before the legendary civilization was lost.
"Now I can reach the Master Emerald again!"
Eggman was astonished at the discovery, but the power stone that the special ring was supposed to guide him to had already been moved to the floating island by the gods who descended from the sky.
However, the mysterious space created by the special ring was filled with "pillar" energy and turned into a ring-shaped crystalline body called a "Chaos Ring."
"If I can find out the secret of this special ring, I can not only find the secret of Sonic's gang's rings, but I can also summon the Master Emerald!"
With that thought in mind, Eggman hastily builds a fortress on the island. The resort, named Newtrogic High Zone, is where Eggman's terrible plans are aswirl.
And when Knuckles arrived near the island, it was all too late. Eggman succeeded in crystallizing the energy. He named the artificial ring the "Dark Ring." He also developed a "ring power" that could generate a space-time connection between the rings.
"With this, there's nothing anyone can do to stop me. No one will be able to get in my way! This time, the whole world will be mine!"
Steadily, Eggman's ambitions were being realized.
Knuckles the Echidna
Guardian of the Master Emerald "pillar" on the legendary floating island. He feels more than a little responsible for the recent commotion.
Espio the Chameleon
Age: 17 years old
Occupation: Private detective
Hobbies: Combat training, intelligence gathering
Dislikes: Dr. Eggman
A single-minded individual with a very strong sense of justice. He is interested in the legendary civilization and decides to visit the island to investigate its relationship with the floating island. For this reason, he is actually envious of Knuckle.
Mighty the Armadillo
Age: 16 years old
Hobbies: Forest bathing
Likes: Tranquility, nature
A traveler who feels that his purpose in life is journeying around the world. When in a tight spot, he can turn on a dime and show off his amazing abilities, but he doesn't like to be rough and is a calm person. He happens to arrive on this island and gets caught up in the commotion...
Vector the Crocodile
Age: 16 years old
Hobbies: Music, dancing, basketball
Likes: Sports drinks
He is boundlessly cheerful and quite an optimist. However, he actually has a stronger sense of camaraderie than anyone else, and has the strength and kindness to face up to any challenge. He believes in the existence of God, and came to this island after hearing the news about an island of miracles.
Likes: The sun, honey
Dislikes: Being mocked
He was the first insect to cross the speed of sound, so he is very proud and can't keep quiet when he is denied. He is also very moody and mature in his words and actions. He is a self-proclaimed "fastest insect in the world" who flew to a new island in search of new flowers.
He is still the same infamous genius scientist. This time, he has his eyes on an ancient special ring on the island of a lost civilization, and plans to get his hands on the Master Emerald, which he says can be summoned by it. His goal, of course, is to become the ruler of the world.
Kameka: It flies unsteadily, but when you pass below it, it swoops down and tackles you. But...
Carry: It carries a heavy-looking cargo. But what's inside that cargo...?
Dribbler: It energetically dribbles bumpers with its two large hands. A bit of a challenging opponent.
Juppun: It swings a spiky pendulum back and forth and slowly moves left and right.
Zakku: It fires out its hook into the ceiling and threatens by swinging its body's spikes.
Gacchi: If it captures you, it traps you in a barrier for a certain time.
Piranie: It slowly flies left and right. Will spit out a bomb from its mouth if approached.
Metal Sonic Kai (Rev.)
A Sonic-shaped robot created by Dr. Eggman. The main and sub CPUs were recovered from the body that was destroyed in a previous confrontation with Sonic. It was replaced by a spare fuselage, which was reborn with Dark Ring power. The newly installed Plasner allows it to perform a plasma pulse attack from its chest.
