Pure Chaos/The Beginning of Disaster
The arc starts with Big and his pal Froggy sleeping when something falling from the sky wakes them up. Froggy hops over to the spot and sees a Chaos Emerald. Big follows and sees the Emerald as well. Then some strange blue liquid comes up behind Froggy and he swallows it. Big asks if his pal is okay and sees that Froggy has somehow grown a tail. Then he swallows the Chaos Emerald Big picked up and hops away with Big in pursuit.

Meanwhile on the President's plane, he remembers what happened six months ago when Chaos Control erupted and two islands, one of them a falling Angel Island, from Sonic's world appear on the coast of Station Square. He and his advisors he has with him on board are planning to boost the economy by turning Mystic Ruins into a tourist attraction. The President then mentions that he's still worried that Dr. Eggman may strike any time soon, but one man says that he's got intelligence teams trying to find him. Rouge suggests that he may be taking a break to plan his next move. The President then asks Mr. Stewart how Sonic and the others are doing. He shows him some photos that they are doing okay.

At the Thorndyke Mansion, he, Chuck, Cream and Cheese are busy having breakfast. Chuck asks if Chris could go with him to Mystic Ruins where Tails has established a workshop, but Chris declines the offer as Lindsey has something to show him, Cream, and Cheese after school. After leaving the house, Chris looks up at the sky and thinks to himself, "I know you're out there, Sonic. I sure hope you're okay." Meanwhile in a valley, Sonic is heard whistling.

Elsewhere in Station Square, Amy has moved to an apartment building and thinking how bored she is and how she misses Sonic and the others. On her small TV set, Scarlet Garcia mentions that the whereabouts of Eggman are still unknown. Meanwhile, Eggman in his new fortress has finished manufacturing a new line of robots: the E-100 Series, consisting of E-101 Beta, E-102 Gamma, E-103 Delta and E-104 Epsilon. He tests them by ordering them to destroy Sonic dolls Then he says it's time to create chaos, walks over to a Chaos Emerald and launches his new flying fortress, the Egg Carrier.

Meanwhile, Lindsey shows Chris, Cream and Cheese a Chaos Emerald she got from a jewelry store. She gives it to Cream as it does not match any of her outfits. Later, the three of them are walking down the street when Cheese gets mixed up with Froggy. Later, Big accidentally piles on top of all of them and Froggy hops away again. Big tries to explain to Chris and Cream what was going on which takes all afternoon. They both offer to help look for Froggy which takes them into the night. After many hours of searching, they find something, but it's not Froggy, it's some of the strange liquid that Froggy swallowed. It reforms to show a creature. Then it starts destroying everything in sight, scaring the people away. Chris, Cream and Big start running away while it's not looking. Elsewhere, Sonic catches sight of the commotion and steps in to help stop it. Chris is happy to see Sonic again. Sonic begins to fight the creature and easily defeats it. Then Eggman shows up and takes Cream's Chaos Emerald and feeds it to the creature whom he calls "Chaos", transforming it into Chaos 1. Eggman then tells Sonic and his friends about Chaos and how each time he gets a Chaos Emerald, Chaos becomes bigger and stronger.

When Chaos 1 is about to attack, an angry Knuckles shows up asking Eggman about the Master Emerald which also made its way into the Chaos Control. Eggman then gives Chaos 1 another Chaos Emerald transforming him into Chaos 2. Sonic and Knuckles try their hardest to fight Chaos 2, and with luck they manage to defeat it. Afterwards, Eggman sucks up Chaos 2 into his Egg Pod and flies away. Sonic and his friends are positive that Eggman will be back, as well as the Chaos creature. Meanwhile, Sonic and his friends think of how powerful Chaos was with two emeralds; it makes them think, "What if he gets more Chaos Emeralds!"

A Chaotic Day/The Mysterious Life Form Chaos
Sonic, Knuckles, Chris, Big and Chuck are having a coffee break to unwrap the mystery of Chaos. Knuckles says it would be troublesome to defeat Chaos. He explains that after Chaos Control happened, Angel Island was transported into this world, and while Knuckles was guarding the Master Emerald, Chaos destroyed it; which made Angel Island fall into the ocean. Chris asks Big if he saw something in the forest that looked like Chaos while he was looking for Froggy. Big explains that after Froggy swallowed the blue puddle in the previous episode, he grew a tail. Big said he tried to catch him, but he was faster than him and hopped away with something he found in the forest.

Big said it was a purple rock, and Chris figured out it was a Chaos Emerald. Chuck says that they'd better find Froggy fast or it won't survive long, because Eggman will do anything to seize an Emerald and give it to Chaos. Sonic decides to go find Tails to help him look for the Chaos Emeralds, and Knuckles would go look for the pieces of the Master Emerald; while Chris and Big decide to find Froggy together. Sonic goes over to Tails' Workshop at Windy Valley, and explains to Tails about Chaos. Tails says he found a Chaos Emerald which it can be used to find the other emeralds. Sonic and Tails then hop in the X-Tornado and start searching in Windy Valley. Meanwhile, back at Casinopolis, Knuckles sees that police are investigating the crime that happened because of the hole in the building. Knuckles asks what the crime was, and a policeman says that a glowing object fell from the sky. Knuckles and the police go inside to look. When they find an Emerald Shard, Knuckles picks it up, but is transported to a version of Mystic Ruins 4000 years ago. Knuckles walks around and finds an echidna named Tikal with her father, Pachacamac. Tikal begs her father not to seize the Chaos Emeralds, but as her father ignores her, Knuckles is transported back to Casinopolis of the present. The police decides to let Knuckles keep the piece of the Master Emerald and Knuckles continues his search.

Back in Windy Valley, the X-Tornado has just detected a Chaos Emerald somewhere in the valley. Sonic and Tails walk around and search. Tails is almost blown away by the valley's strong winds, but Sonic catches him at the last second. Tails says that the Chaos Emerald is buried underground, so Sonic uses a Ring to dig underground and successfully finds the cyan Chaos Emerald. Eggman arrives and charges at Sonic and Tails and he misses. Tails drops the Emeralds, and Eggman steals them. As Eggman flies away, Sonic jumps on-board his Egg Hornet, but Eggman activates the Egg Hornet's drills and knocks Sonic off. Just as Eggman is about to drill a hole in Sonic's body, Tails throws a Ring in Sonic's hand and uses his Spin Attack against a drill. Eventually, Sonic's powered up spin was too much for pressure for the drill to handle and they shattered. Eggman tries to escape, but seemingly accidentally spilled the Emeralds he stole into a lake. This is part of his plan however, because Chaos is in that lake. Using the two Chaos Emeralds, Chaos 2 transforms into Chaos 4. Chaos 4 uses a windy wave to blow Sonic and Tails away. Sonic attacks, but Chaos 4 submerges underwater and Sonic lands on a lily pad just in time. Chaos uses a tornado to knock Sonic off the lily pad, but there are more lily pads around so Sonic uses them for a surprise attack on Chaos 4. Sonic and Tails think that Chaos has been defeated, but he is not. Chaos 4 uses another windy wave in an attempt to knock Sonic out, but Sonic jumps and tries to attack Chaos 4. When he goes underwater, so does Sonic. Chaos 4 keeps dunking Sonic, but as Sonic feels the wind, and it gives him an idea. He then uses the wind to charge at Chaos 4 at a speed. His plan succeeds as Chaos couldn't reform.

Upset about another losing battle, Eggman retrieves Chaos inside his Egg Mobile and they both retreat to the Egg Carrier. Sonic and Tails use the X-Tornado to give chase to Eggman.

As the Egg Carrier floats above Amy Rose and Station Square, the X-Tornado fires at the Egg Carrier. Eggman fires a Cannon at the X-Tornado, but the X-Tornado destroys it. The explosion of the Cannon causes a Flicky to fall out of the Egg Carrier. The Flicky lands on Amy though despite this, Amy and Cream feel sympathy for it and decided to take care of it. Eggman then tells Decoe and Bocoe to fire the Egg Cannon at the X-Tornado and it destroys the X-Tornado's wing. The X-Tornado goes down and Eggman laughs.

Tails and Sonic survive, however. Tails, passed out by the crash, has a dream about being attacked by an E-12 Behemoth, but Sonic pilots the Tornado and destroys the E-12 Behemoth. Then, more E-12 Behemoths come; but Tails pilots the Tornado and he and Sonic destroy them. Tails wakes up and finds bandages around his head, and Chuck tells him that the X-Tornado has taken heavy damage, but they'll get Eggman the next time. Amy and Cream went shopping, so Sonic has gone to check on them. Amy, Cream, Cheese and the Flicky decide to cook a gourmet meal for Sonic after he and Tails crashed. Cream asks the Flicky where it came from and if it has a name. Amy decides to name the Flicky "Lily" and the Flicky likes that name. Lily is happy about her new name, but the happiness didn't last for long. ZERO recognizes Lily, and grabs her and Amy. Sonic hears Amy's scream, and tries to destroy Zero, but no luck. Zero uses his jet packs to fly away and Amy and Lily are captured.

A Robot Rebels/Amy the Captive
Knuckles is pouting about failing his duty of guarding the Master Emerald and that he only has one Emerald Shard. He thinks he failed his duty, but then sees another vision of the past where the shrine is covered with flames and a worried Tikal looking on. He then realizes that feeling sorry for himself won't help and he continues his search. Meanwhile, Sonic and Tails take off in the X Tornado to go after the Egg Carrier to save Amy with Chuck, Cream and Cheese worried but Mr. Tanka and Ella reassured that the heroic duo will be determined to bring Amy home safe and sound. Sonic tells Tails that he shouldn't try to take Eggman on while still recovering, and that he should do it alone. Tails reminds Sonic that the two of them together are a team and it will be easier if they both look together. Meanwhile, Chris and Big are still looking for Froggy, when Chris spots the X Tornado flying overhead and wonders if Tails is okay.

Inside the Egg Carrier (which is hidden underwater), Amy is locked in a dungeon with Lily and calls to Eggman to let her out, but nothing happens. She was upset that Eggman had to spoil a nice gourmet meal she was going to make for Sonic. She then remembers a time chasing after him when she is suddenly attacked by an E-12 Behemoth, but Sonic destroyed it and saved her. She then said to Lily that Sonic would come to save them. Elsewhere on the Egg Carrier, Decoe and Bocoe are arguing with each other on who should test the microphone until Eggman cuts them off. The doctor gives orders to Beta, Gamma, Delta and Epsilon to find Froggy, an unusual frog with a long tail. Without questions, all of the robots leave the Egg Carrier to complete their mission.

Meanwhile, Knuckles finds more shards of the Master Emerald and is sent back into the past again to Tikal, a group of Chao and the Master Emerald shrine. The Chao lead her to the top of the shrine and show her the seven Chaos Emeralds and the Master Emerald, and she realizes that the Master Emerald is the controller that unifies the Chaos. Knuckles is then sent back to the present time in front of the shrine. He then puts together the Emerald Shards he gathered and the Emerald is almost complete. He notices that there is one piece left. The Master Emerald then shows Knuckles an image of the Egg Carrier. As Knuckles wonders why the Master Emerald shows the image, he suspects that Doctor Eggman is up to his evil schemes as usual.

Beta, Gamma, Delta and Epsilon are still searching for Froggy and they are near where Chris and Big are. Beta, Delta and Epsilon all find frogs which don't appear to represent the frog Eggman wanted. Although Gamma hasn't retrieved a frog yet, he notices Big and Chris have fished out Froggy but Gamma steals Froggy afterwards. Chris and Big follow Gamma on to the Egg Carrier. The robots all displayed their frogs with each claiming that they found the real Froggy until Decoe and Bocoe snaps at them to settle down. When Eggman sees the frogs with no tails he gets enraged at his robots, but then he sees Froggy in Gamma's hand and is delighted that Gamma succeeded. He then tells Decoe and Bocoe to eliminate Beta, Delta and Epsilon, much to the Decoe and Bocoe's dismay. Eggman then tells Gamma to get Lily from Amy. He walks into a room and sees Beta being modified. This somehow upsets him but quickly leaves to resume his mission. When he reaches Amy's cell, Gamma points its gun at Amy and demands Amy to surrender Lily to him. She refuses to give up Lily and asks him why he wants Lily. Gamma simply responds that he must obey the doctor's orders. When Lily flies in front of his eyes, his systems overload. He then shoots at the bars freeing Amy and Lily. Amy notes that Gamma isn't quite like the other robots and thanks him before prompting to leave.

Elsewhere, Sonic and Tails find Knuckles and he joins them on board. A battle then ensues between the Egg Carrier and the X Tornado. Tails then springs a surprise on Eggman and transforms the X Tornado into Battle Armor mode. Eggman then transforms his Egg Carrier into Battle Mode as well. Tails manages to destroy any missiles being fired and brings the X Tornado close enough to land. Sonic tells Tails to bring it in for a smooth landing, but Tails said that they'll have to settle for nice and bumpy as he forgot to put wheels in Battle Mode. Sonic and Knuckles both exclaim, "WHAT?!?!" as the X Tornado crash lands on the Egg Carrier.

Head's Up, Tails!/Egg Carrier Battle
After crash-landing on the Egg Carrier, Sonic, Tails and Knuckles start to carry out their missions. Doctor Eggman starts launching missiles at Sonic, but he easily dodges them. One missile hits the Egg Carrier which opens up a hole. Knuckles leaves Sonic and Tails to search for the last piece of the Master Emerald. Eggman then calls Gamma and orders him to come to the control deck.

Amy makes her way out but she's caught by Bocoe and Decoe. She then pulls out her Piko Piko Hammer but is stopped by Eggman. Sonic then says to let her go, but Amy frees herself, hits Eggman, Bocoe, and Decoe, and slams the wall making Sonic and Tails fall on Eggman. Decoe then snatches Lily, and Eggman gets Sonic and Tails off of him. He then grabs the terrified Lily's necklace and a Chaos Emerald pops out. He then orders Decoe to give back Lily. Gamma then appears to the deck, and Eggman orders him to get rid of Sonic. Amy tries to get them to stop, but it does no good. Sonic defeats Gamma and is about to finish him off when Amy gets in his way. She tells him that Gamma set her and Lily free. Sonic believes her. An explosion then goes off behind them. Tails says that the ship is losing altitude. Sonic tells Tails to get Amy and Lily down to safety while he searches for Eggman. Amy manages to get Gamma to reboot. Gamma asks Amy why he saved her. She replies that she was just returning the favor he did for her earlier. The three of them then leave the Egg Carrier.

Meanwhile, Chris and Big manage to find Froggy in a room. When they're about to get him, an explosion causes the floor in front of them to break. On the ground, Chuck sees Amy and Tails and takes them in his car back to the house. Tails is still worried about Sonic. Knuckles manages to find the last piece of the Master Emerald, and starts to find a way out, when he's sent back into the past again. He spots an injured Tikal and some unconscious Chao on the ground in front of the shrine. She tells him that she tried to stop her father, but he didn't listen to her. Knuckles is then sent back into the present and wonders why he's being sent back to the past. Big is panicking that he and Chris might not get Froggy back to safety, but a quick drink manages to calm his nerves. Big uses his fishing pole to allow Chris to try to reach Froggy, and he manages to get him. When they reach the deck, they spot Chaos and Eggman.

Eggman tells Chaos that Froggy has an unusual tail. He starts chasing Chris and Big, jumps in front of them, and knocks Big down. Eggman picks up Froggy and chokes the Chaos Emerald out of him. He then feeds it and the Emerald from Lily to Chaos 4 turning him into Chaos 6. He then feeds Froggy to Chaos 6 to give him back his tail. Big tries to save him, but his face plants into Chaos 6 instead. Chris then climbs on top of Big and attempts to rescue Froggy, but Chaos sucks them in. Froggy's tail then disappears and reappears on Chaos. Sonic then appears and sees Chris inside Chaos. He attempts to rescue him, but gets pinned down. Knuckles shows up holding up the tentacle that had Sonic down. They both then come up with a plan to free Chris, Big, and Froggy. They find Chaos' weak spot and use the Shovel Claws to expose it. Chaos 6, being defeated, is then reverted back to Chaos 0, and Knuckles picks up the Emeralds. Sonic goes after Eggman, while Chris, Knuckles and Big are left with the X Tornado. Bocoe and Decoe have no choice but to bail out.

Back at Chris' house, Lily shows Amy a picture of her brother and sister, and that she misses them. Amy offers to help find them. Meanwhile, Sonic falls off his ride with Eggman and lands headfirst in the dirt. After getting out, he finds himself in Mystic Ruins. Meanwhile, Eggman sets up a missile and it lands in the middle of Station Square scheduled to detonate in two minutes. Tails thought that Sonic would know what to do if he were here. The people nearby begin looking at Tails hoping he could defuse the missile. Tails is hesitant at first but decides to give it a go. He starts thinking of the time he first met Sonic, and how he was always there for Tails, but thinks he should start doing things on his own. He then figures out which wire to cut and successfully defuses the missile.

Meanwhile, Chris, Big, and Knuckles land the X Tornado near Mystic Ruins. Knuckles goes to Angel Island to fully restore the Master Emerald, but moments after he left, Chris spots the last Chaos Emerald near the X Tornado and rushes off to give it to Knuckles. Big and Froggy then decide to head home.

Revenge of the Robot/Gamma the Wanderer
After saving Station Square from Dr. Eggman's dreaded big missile in the previous episode, every civilian wants to see Tails after he deactivated Eggman's missile. After escaping, thanks to Ella and Mr. Tanaka, Tails was able to escape from the crowd ready to honor him. Meanwhile Gamma is remembering various moments with his other E-Series brothers and Amy. Gamma then decided to delete Eggman's control over him and set himself free with a new mission: to find his E-Series brothers and rescue their animals. Meanwhile, Sonic was chasing Tikal's soul into a petrified temple with a tree on top. When Tikal's soul went through a little waterfall in the temple Sonic went in while sad Chao were staring at him. After Sonic saw a picture of Perfect Chaos, Tikal's soul took the hedgehog back in time to Angel Island in flames. Sonic saw Tikal lying down with a Chao on her hand weeping after her father took the Chaos Emeralds, Tikal told the Master Emerald to stop them and Sonic blasted away from the past in a flash. Sonic was in front of the temple confused and knew that it was not a dream but something much more, then Sonic saw Eggman flying in his Egg Mobile.

Sonic pursued the mad scientist and smashed into his base, triggering an alarm, Eggman raged after seeing the blue hedgehog. Eggman shoots lasers beams which all miss the speedy hedgehog but Eggman managed to trap Sonic in place at a high speed conveyor belt inside a tunnel. Eggman releases big ball at Sonic but he manged to counter it causing him to blast everywhere until he hit the exit. Eggman scowls at this. Sonic, taunting that he is too fast for Eggman to catch him is rushing until Bokkun surprised him. He gave Sonic a message telling him to go to the lower chamber. Eggman, very furious at Sonic for trampling his schemes for years, unleashed his dreaded new machine, the Egg Viper. Dr. Eggman attacks Sonic but the hedgehog dodges it; the doctor then turned to the ceiling in the air which seemingly disappears making Sonic calling him a coward. The Egg Viper surprised Sonic from the floor below and crushes the hedgehog with its tail. Despite this, Sonic somehow manages to destroy the tail and destroys the Egg Viper. Eggman, swearing for eternal revenge, quickly abandons his base. Sonic escapes as well, leaving the base to explode in flames..

Meanwhile Gamma is hovering around as he managed to pick up a location of a E-series robot at Windy Valley while Amy and Lily sad that Lily's family on the Egg Carrier. Big and Froggy met Amy for the first time and told them where the Egg Carrier was. Meanwhile, Gamma deleted Eggman's data from Delta, still referring to Eggman as his master, then he found Episilon and also deleted Eggman's data from his memory banks. Then Gamma remembered that Beta is still in the Egg Carrier and he then flew off to his next destination. Then Amy and Lily were rowing to the Egg Carrier and Gamma went in the Egg Carrier to find Beta. Amy and Lily wondered if Gamma has already set free Lily's family, as she was still searching for them.

Decoe, Bocoe and ZERO chased after Amy. Then, after realizing that Beta and Gamma have Lily's siblings trapped in them, Amy fought ZERO with her hammer leaving ZERO defeated on Eggman's robot henchmen. Gamma crosses path with a newly re-configured Beta MkII Gamma are fighting. Amy told them to stop, but Beta was still loyal to Dr. Eggman and wouldn't surrender. Gamma and Beta both shot through each other at the same time leaving both destroyed on flat on the floor. Before Gamma fell, he knew his mission was completed. Then he fell dead on the floor with flames around him. Lily's family was reunited but Amy was heartbroken for his destruction and said to Gamma that she will always remember him. Sonic and Tails are relaxing while Doctor Eggman is cursing at Sonic due to his defeat and meets with Chaos. Knuckles strolls along at a different section of Mystic Ruins and then stares at the thunderstorm at Angel Island.

Flood Fight/The Scream of Perfect Chaos

The episode starts with Frances, Danny and Helen playing basketball while Mr. Stewart informs the government that Chris is missing. Chris is waiting for Sonic and Tails in Tails' workshop but the heroic duo doesn't show up as he still intends to look for Knuckles and give him the white Chaos Emerald. However, Sonic and Tails encounter Knuckles in Mystic Ruins standing beside Dr. Eggman who is lying unconsciously on the ground. Sonic questions Knuckles how Eggman came into this state with Knuckles responding that he had found Eggman this way. Tails grabs a stick and starts poking Eggman until he surprisingly wakes up. Sonic asks what happened to Eggman with the doctor responding that Chaos double-crossed him and he wants to utilize the power of the Chaos Emeralds for his own ambitions. Knuckles begins to threaten the doctor when Sonic tells Knuckles to calm down. Eggman snapped at Knuckles' actions before being escorted away by Decoe and Bocoe on a balloon.

Knuckles proceeds to tell Sonic and Tails that if Chaos gets a hold of the last Emerald, he will become too powerful. Suddenly a red orb transports Sonic and Knuckles back into the past of Angel Island, where they witnessed Tikal trying to stop Pachacamac from invading the Master Emerald's shrine. Despite this, Pachacamac orders his clan to strike. They ran over the defenseless Tikal and some Chao down to the ground. Chaos, witnessing all of what has been happening by Pachacamac and his clan, appears as they confusedly encounter him. Then, Chaos absorbs the power of the Emeralds' to destroy Pachacamac and his clan, which is their punishment. After that, the Master Emerald seals Chaos inside itself, instantly. Sonic and Knuckles rushed to Tikal's aid with her being sad of her father not listening to her. The three of them walked together to the top of the Master Emerald's shrine with Tikal saying a prayer. Sonic and Knuckles eventually are transported to the present with Tails.

Chris calls out to the heroes, running to them while holding out the seventh Chaos Emerald. Knuckles hesitates, making Chris slow down. Suddenly a burst of water appears and forms into a whirlpool, sucking Chris in. Sonic jumps in to save Chris while Knuckles punches the vortex, splitting it into halves. Despite this, the Chaos Emeralds are dropped and a hole in the ground opens up with the wave of water appearing from it and the Chaos Emeralds successfully falls into the water before disappearing. Believing that the water was Chaos, Knuckles begins to lose hope now that all seven Chaos Emeralds are in Chaos' possession, Chaos would be too powerful to defeat. Sonic, with a determined look in his face, says that they'll need to try defeating it somehow. Not far behind a colony of Chao appears.

In the relatively peaceful Station Square, the civilians are enjoying their daily activities when suddenly they hear a rumble underground. While Sam Speed warns an over-speeding driver, columns of water suddenly rocket upwards from all of the drain sewers like geysers while more water emerges from buildings and roads creating fissure cracks. While Sam escorts civilians to a nearby safe building, a tsunami forms, washing Sam away. One trail of water forms a face, the powerful deity of Perfect Chaos. Chuck, Ella, Cream and Cheese proceed to evacuate to some mountains while Sonic, Tails and Chris take off to the flooded and ruined Station Square. The government attempts to shoot down Chaos with choppers but their weapons prove no match against the water monster's watery skin. Perfect Chaos launches the missiles back at their sources, destroying the choppers but the pilots survive. Meanwhile, Eggman, Decoe and Bocoe launches the Egg Carrier 2 in hopes of defeating Perfect Chaos as revenge for betraying Eggman. Sonic attempts to take down Perfect Chaos but serves no match to it. Perfect Chaos creates another tidal wave to drown Sonic only for the blue hedgehog to be alive surfing on a wooden plank. Chris rescues him back on to the X-Tornado. Chaos then tries to shoot down the X-Tornado using spears of water but the X-Tornado dodges them and flies past Chaos. Looking upwards, Sonic notices the Egg Carrier 2 who Eggman is attempting to defeat Chaos with but it gets shot down with a powerful laser.

Suddenly a bright light blinds Chaos and the X-Tornado's passengers as the X-Tornado lands on a piece of highway by the light. The light reveals itself as Tikal who has arrived from the past who also wishes to stop the water monstrosity. Sonic suspects that Eggman initially somehow figured a way to revive Chaos so he can use it to take over the world. Perfect Chaos then spits out the Chaos Emeralds, now drained of their power. Tikal states that Perfect Chaos is only full of hatred and sadness and suggests sealing him back in the Master Emerald before it is too late, but Sonic replies that it will not work, if they do that, the same thing will only happen again and they have to solve the problem once and for all. Tails, Amy, Cream, Knuckles, Chris, Big and Eggman find the Chaos Emeralds and meet up with Sonic. The crowed cheers the blue hedgehog on; suddenly, the Chaos Emeralds started to glow and rise up. Their powers transform Sonic into Super Sonic, much to the surprise of Tikal who thought that the Emeralds could only be awakened by hate and anger. Tails and Knuckles reply that there are other more powerful feelings such as caring and friendship.

With his new powers, Super Sonic proceeds to fight with Perfect Chaos. Despite all of Perfect Chaos' attacks, they proved ineffective against the super-powered hedgehog though at one point it fires a laser at Sonic' friends but Super Sonic arrives to the scene and stops the laser, which only provokes Super Sonic to redouble his attacks. With one final punch with stopping the laser and charging into Perfect Chaos by plunging right down its gullet, Super Sonic defeats the water monstrosity for good but Chaos 0 emerges from a water puddle; he is not defeated entirely yet and is still alive. A Chao colony arrives, much in the favor of Chaos and Tikal tells Chaos the truth that the Chao are living in Earth at peace before they both disappear together. While the heroes are happy with the resolution, they realized that Dr. Eggman has left the scene.
