They continue their journey for the Master Emerald.
Somewhere in the distant future, Silver is seen confronting Dr. Eggman Nega's base. Battleships and troops are seen entering and exiting the base.

Fleet: Boss: Gravitus Marshall) (Playable Characters: Shadow, Rouge, Omega).

Eggman agrees and orders his robots to strike the Gravitus down with his Egg Fleet at the skies of Angel Island. (You can click here to see an image from DeviantART to get an idea of how the Angel Island would look like.)
(Angel Island: Regal Sanctuary) & (Angel Island: Hidden Palace) (Playable Characters: Sonic, Tails, Amy, Zeline). The team arrives at the Master Emerald shrine. Suddenly, Dr. Eggman Nega appears with the Gravitus fleet in the sky and unleashes its army to steal the Master Emerald and capture Sonic and his friends. Sonic, Tails, Amy and Zeline battle their way through Dr. Eggman Nega's mechs but are unable to defeat them all due to being unlimited. At that moment, Knuckles jumps out of the bushes along with Shade on his side and assist the heroes. (Angel Island: Mission: Defeat 25 enemies) & (Angel Island: Boss: Egg Brawler) (Playable Characters: Sonic, Tails, Knuckles, Amy, Zeline, Shade). Dr. Eggman Nega's army surrounds Sonic and his friends with no way to escape. Knuckles, then, punches the earth and creates a pit which causes the heroes to fall in it. After being unconsious for a while, they wake up in front of a large gate. They examine it. Sonic notices seven large carvings on it and the first two of them have been lit and pushed inside. Shade explains them that these carvings were created thousands of years before by the Echidna Tribe, that represent 7 prophecies. The first carvings decipts a comet while the seconds decipts a strange-looking creature, heavily armored. The third one, which has not yet been lit decipts a talisman followed by the fourth which decipts a gigantic half-moon-like thing. The fifth carving decipts a city with tall buildings. The seventh decipts a blur silhouette and the seventh final carving decipts a huge, terrifying monster. However Sonic spots another carving behind some rotten vines. It is half-destroyed and the only thing visible is the body of someone. The heroes do not understand what those carvings mean. Tails takes some pictures with his his camera to analyze them later. Amy spots a text written below all these carvings. Knuckles tries to read it but doesn't succeed since he isn't familiar with the language. Shade gives it a try and succeeds.
As the gate opens, the heroes witness a golden empire with large mausoleums and water. They wander around until they are seized by hooded figures and taken to the emperor's palace. There, they witness that the entire civilization are Echidnas. When they arrive at the emperor's palace, the emperor appears wearing the Enerjak suit. He walks down the palace and takes off his mask. Knuckles instantly realizes that the emperor is his father Locke. Locke recognizes Knuckles as well and orders his servants to set them free. He then tells them to meet him in his temple to talk. (Teotihuacan: Gold Kingdom) (Playable Characters: Sonic, Tails, Knuckles, Amy, Zeline, Shade). At the palace, Locke explains the heroes their story. Once, two different tribes lived together on the Angel Island. The one was known as the Knuckles Clan, while the other one was known as the Nocturnous Tribe and was ruled by Imperator Ix. The Knuckles Clan guarded the Master Emerald for generations. There were times of peace and prosperity. But one day, Imperator Ix's clan declared war against the Knuckles Tribe to take control of the island. The two tribes fought together for years, until Ix's tribe defeated the other. The Knuckles Clan was then sealed in the centre of the Angel Island for all eternity, with no help, and no salvation, never again able to witness the daylight. Sonic explains to Locke their story too and how they got here.
Meanwhile on the surface of Angel Island, Immarius uses the power of his Chaos Emerald to create an earthquake that will allow his army to invade Teotihuacan. Sonic and the others, after realizing the earthquake, rush to the exterior of the palace to see what is going on. The ground of the Angel Island collapses and Immarius appears with his army. He commands his soldiers to attack and destroy the city. They imprison all of the Echidnas and take them to their mothership. They eradicate the entire civilization and grab all of the gold. They also capture Locke. Knuckles wants to go and rescue him but it's too late. Locke gives him a Chaos Emerald and tells them to MountBlueChaos to search for the Pendent of Hope. The heroes flee from the destroyed city, unable to rescue the Echidna Tribe. (Teotihuacan: Lost Relic) & (Teotihuacan: Boss: Gravitus Sentinel) (Playable Characters: Sonic, Tails, Knuckles, Amy, Zeline, Shade).
The game switches back to Silver and Blaze. They find themselves in the ruins of Central City via Dr. Eggman Nega's time machine. Since they do not know where they are, they decide to ask the townspeople for information. After that, they learn that they are at Central City and that certain townspeople saw an "egg-shaped" man heading east. They decide to go that way in order to find Dr. Eggman Nega. (Nonduria: Walking Acropolis) & (Nonduria: Mist Mausoleum) (Playable Characters: Silver, Blaze). Silver and Blaze fail to catch Dr. Eggman Nega. (Nonduria: Boss: Egg Harvester) (Playable Characters: Silver, Blaze). After finding the Chaos Emerald, Silver and Blaze witness a roaring, dragon-shaped cloud in the sky. In order to find out what it is, they head towards its direction.
Shadow, Rouge and Omega, after waking up, appear in a digital cyberworld, the Cyber Circuit. They find some binary codes which form the shape of Immarius' head. Immarius introduces himself and tells them that he is responsible for transfering them here. Omega implies that the only way they can get out of here is to find the Master Core. They then set course to finding the Master Core. (Digital World: Crazy Track) & (Digital World: Cyber Circuit) (Playable Characters: Shadow, Rouge, Omega). Shadow, Rouge and Omega find the Master Core but have to beat a Gravitus guarding it in order to pass through. (Digital World: Boss: Gravitus Virus) (Playable Characters: Shadow, Rouge, Omega).

At another part of the Angel Island, Cream and Cheese are picking up flowers when they are suddenly attacked by Gravitus. Big ends up in the same place while chasing Froggy and encounters Cream in danger. He rushes to the rescue to save his friend. (Mystic Ruins: Mission: Defeat 30 enemies) (Playable Characters: Cream, Big). After saving her, he explains to her that he is searching for Froggy who has ran away cause he got frightened by the earthquake. Cream and Cheese offer to assist Big in finding his frog.
Immarius' mothership launches 6 massive chains which are attached to the Angel Island and starts absorbing its energy. The mothership prepares to depart. Sonic and his team escape from the city and are attacked again by Gravitus. (Teotihuacan: Mission: Defeat 35 enemies) (Playable Characters: Sonic, Tails, Knuckles, Amy, Zeline, Shade). Before Immarius' armada can depart along with the Angel Island itself, the Egg Fleet appears in the sky and launches a laser beam which destroys 2 of the 6 chains. He then releases his troops to battle the Gravitus. However, Amy somehow gets mixed up in the battle, causing her to get kidnapped by one of Eggman's robots. Sonic and the rest head to Eggman's air fleet in order to rescue her.

Back at the Egg Carrier, Amy is trying to escape while hiding from the Egg Troops. She enters a secret room in which there is a tube with E-102 Gamma in it.

He remembers that it was Amy who saved him from Sonic at the Egg Carrier in Sonic Adventure and immediately takes action. He breaks out of the tube and attacks Eggman's robots, saving Amy.

After defeating Eggman, Sonic asks Eggman what his relationships with the Gravitus are and what are his plans. Eggman tells them that he is not working for them and wishes to exterminate them in order to conquer the world himself. Eggman then tells the heroes that they should work together to stop the Gravitus since they both have the same enemy. The heroes doubt that Eggman will help them since he is their arch-enemy. Eggman insists that he will and tells them that he will guide them to the Chaos Emeralds. Sonic accepts his offer. Eggman searches his computer and detects the 5th Chaos Emerald in a place called the BlueChaos Mountain. Eggman tells them that he cannot go with them because he has to stay in E.G.G.

He tells them that Immarius is actually searching for the 7 Chaos Emeralds in order to revive a fearsome creature from beneath the Earth known as Dark Legion. He was once a very powerful demon who caused chaos and destruction to the world but was sealed inside the Earth's core for eternity and the only way to awaken him is with the power of the Chaos Emeralds or the Master Emerald. Tails gives out Professor Pickle some of the pictures he took from the mysterious gate. Pickle and his assistant examine them. He tells the heroes that these are the 7 prophecies. Each one represents 1 prophecy and those which have been lit have already come true. The explains them all. The first one is a comet, the second one is a mere Gravitus soldier which decipts the invasion of the Gravitus.

Suddenly, the Chaos Emeralds start glowing and a blue flame surrounds them, somehow triggering Chaos Control and teleport all of the heroes. Sonic wakes up in a jungle. He decides to explore it if he can find any of his friends. (Destiny Path) (Playable Characters: Sonic, Jet, Omega, Cream, Amy, Shadow, Blaze, Espio, Mighty, Charmy, Metal Sonic, Tails, Gamma, Rouge, Dr. Eggman, Shade, Big, Zeline, Silver, Vector, Knuckles, Fang) (NOTE: Sonic is the only available character at the start of the stage, the rest are found during the stage, Wave, Storm and Omni-Viewer can also be found but not played).

Eggman tells them that the power of the Chaos Emeralds activated, resulting to Chaos Control which teleported them here. Mighty spots a large ancient temple just a little further. The heroes go into it and as the gate opens, they enter a dark world similar to a digital one. As they wander in it, they find Immarius on top of an altar. The heroes and Immarius have a short conversation about his plans until Zeline steps in and hands the Chaos Emeralds over to Immarius, betraying the heroes. Zeline explains them that she had been working with Immarius from the beginning. She tells them that Immarius and her made a deal. She would gather all of the Chaos Emeralds for him in order to ressurect Dark Legion and Immarius would free her people and her family. Zeline starts crying and regrets everything she had done. Sonic tells her that she has another option and that she can still help the heroes. Together, they can stop Immarius' plans and free her family and people. Knuckles gets frustrated with all the talking and attacks Zeline. Immarius creates a field and protects her. Immarius then tells Zeline that her people and family are all dead and that he had lied all along about them being in captivity. He grabs his sword and stabs Zeline, stealing the Chaos Emeralds from her. The heroes rush to her side. Immarius places the Chaos Emeralds on the altar in proper order and uses Chaos Reverse to ressurect Dark Legion. Immediately, Sonic runs to the altar and touches the Emeralds, absorbing their energy and transforms into Super Sonic. Immarius unleashes an army of Gravitus from his flame core. The heroes protect Zeline while Sonic battles Immarius in his super form. At that moment, Cheese rises in the air and covers himself in a blue barrier of water and transforms into Chaos, revealing that Cheese was Chaos all along. (Supremacy) (Playable Character: Super Sonic). Sonic continues to fight Immarius in his super form while the rest of the heroes battle the Gravitus army. Since Immarius can control this world, he rises buildings from the floor to hit Sonic. Despite Immarius' efforts, Sonic breaks his sword and punches him in his core, ultimately defeating him. On the ground, Immarius tells Sonic that the battle is over and that he (Sonic) lost. He grabs the remaining flame from his core and frees it into the sky which attract the Chaos Emeralds with it and seperates each one of them to a different place. Immarius' armor breaks into pieces. The heroes realize that it's too late and Dark Legion has already been ressurected. Suddenly, the entire place starts collapsing.

Zeline, hoewver, tells them that Dark Legion cannot die in their world because there is danger that if he dies in the same world as the heroes, he might one day be ressurected again and destroy the world. The only way is to use Chaos Control and teleport him into another dimension and seal him there forever. Doing this will result in getting herself sealed in that dimension for ever as well. Sonic tells her that it's too dangerous and that he will do it as he is fast enough to escape. Zeline denies; he must remain here to protect humanity at all cost and stand up for his friends.
