Chapter 4: The Chai
The group is left scratching their heads after the Chaos Emeralds fail to produce the Chaos Force, but rather, the evil Chaos Eater. The dark demon mocked the idea of granting wishes as Blaze demanded he do so. Calmly lighting a marijuana cigar, he took pleasure in Blaze's fear, flaunting his superiority over the group. Using his power, the demon levitates the Chaos Emeralds around himself before sucking them into his body and unleashing the Chai on the world, leaving behind a beautiful aurora across the sky.
Just then, King Lazaar begins to telepathically communicate with the group, warning them about this demon. Before King Lazaar can explain what is happening, Old Lazaar interrupts to lecture the group about overuse of the Chaos Emeralds and disruption of the natural orders of things. He goes on to explain that the Chai which were created are not only capable of destroying Mobius, but the entire universe as well. Annoyed by the elder's yelling, Rouge demands he be quiet and they enter into an argument about respect and who is to blame for the overuse of the Chaos Emeralds. Mogul Lazaar brings order to the group and explains that with every wish they made with positive energy created equal and opposite negative energy. Without proper time to dissipate naturally (100 years per wish), the evil reached a critical mass and was unleashed upon the universe. This happened before with the Super Emeralds on Chidnai, but the Echidnas were able to deal with the problem while it was in the early stages.
Old Lazaar reiterates the dangers of overuse of the Chaos Emeralds and again blames Rouge, who shifts the blame to Tikal for not warning the group. She then tries to get the entire group to stand behind her, but they do not. She finally reimagines the events of Sonic to the West in which she was helpless and corruptible until Sonic came along and caused her to hunt for the Chaos Emeralds. To Rouge's surprise, Sonic takes full responsibility without argument and calmly prepares to fix the mess he got everyone into. Old Lazaar tells Sonic that time is running low and he is all the more ready to fight. Charlie tries to join his father, but Sonic insists against it being overly confident having achieved Omega Hedgehog. The family sends Sonic off on the Tornado (so the Chai don't sense his energy) with well wishes. As he flies away, Blaze slips away unnoticed.
Not long after leaving, Sonic recognizes a horrible trail of devastation stretched out below him. All of the Chai are shown making home in their respective environments: Flame Eater finds home inside of a volcano causing it to explode and destroy a village, Ice Eater flies through the mountains coating his body in ice before finally stopping, Spark Eater is seen as lightning in a thunder storm coming down into a city and causing a massive explosion, Water Eater is shown decimating a city with a ferocious tornado, Nature Eater is shown coming out of the ground as a glorious dragon made of dirt, and Poison Eater is shown as a large whirlpool dragon which comes out of in his more familiar form before polluting and destroying all living things over a large radius.
As he begins his search Sonic remembers that he can sense the Eaters' powers, but not the Chaos Emeralds. As he turns around to go back, he sees that Blaze has been following him the whole time. Lucky for Sonic, Blaze had the forethought to bring Yacker (who has the ability to sense the Chaos Emeralds after eating the Chaos Radar) along with her. However, Blaze insists that if she does not go either does Yacker. Against his best judgment Sonic reluctantly allows Blaze to come along with him. They ask Yacker where the Chaos Emerald is located and out of fear he will not give any answer more specific than "down below." Without help from Yacker, Sonic and Blaze notice villagers running through a polluted corridor of sludge. They spot Poison Eater terrorizing and innocent woman, and Blaze becomes so angry that she goes flying towards Poison, kicking him in the face. To everyone's surprise he is sent flying. He tries to respond by speaking aggressively, but is made to look like a fool when rubble lands on his foot leaving him sobbing in pain.
Sonic, Blaze and Yacker confront Poison Eater, the Orange Chaos Eater, who is terrorizing a village near a lake. All of them believe that he is unbelievably weak, but Poison Eater insists that he is the strongest of the seven evil Chai. Blaze smacks Poison Eater into a cliff and asks for the Orange Emerald. Poison Eater begins to grow in size, making Sonic believe that he'll transform, but the Chai says that he doesn't have that ability. He says that transformations are for cowards who are cornered and that a truly strong warrior doesn't need them. Blaze begins to use Poison Eater as a punching bag and beats him all over the area. Blaze then asks for the Orange Emerald again, but Poison says that the fight has just begun. Sonic says that there's too much difference in power between them and that the evil Chai is just like Fang.
Poison Eater attacks with his tail, but Blaze dodges out of the way and drop kicks him from the sky. The Chai asks Blaze if she is collecting the Chaos Emeralds to make herself less ugly and, for that remark, Blaze beats him up worse than before. Poison begins to laugh and Sonic says that something strange is happening because Blaze is getting more fatigued while Poison Eater isn't even out of breath. Blaze attacks again but to her surprise Poison is able to block all her punches. The Chai then punches Blaze in the stomach and Sonic charges at him, but his attack is dodged and both Blaze and Sonic are head-butted together. Blaze and Sonic attack again, but Blaze is locked in Poison Eater's grip while Sonic is tail-slapped away. Poison says that he is going to eat Blaze now, but Sonic is determined to stop him by transforming into his Super Hedgehog form. However, he reverts back to normal and wonders what happened.
The evil Chai tells them to look at the polluted lake to find out why they are losing their power. Poison Eater's body releases minus energy which turned the lake's water into poison. Furthermore, it turns into minus fog, giving off poison minus energy all around the area and the minus energy got into their bodies while they were fighting the evil Chai. Blaze understands now that it is not Poison Eater who got stronger, but they got weaker instead. Sonic says that it is an unfair trick, but Poison says that it is their fault that they didn't notice the minus energy. Blaze wants to know what minus energy is, so Poison Eater explains it by asking Sonic if he knows a girl named Cream. Sonic then remembers when, many years before, Mercenary Sleet killed Cream's father and he used the Chaos Emeralds to ask the Chaos Force to resurrect him.
Poison Eater says that he was born from the minus energy of that wish and thanks Sonic for bringing him into existence. The evil dragon then uses Blaze like a bowling ball and rolls her at Sonic, striking him. Sonic says that he must defeat him, but Poison says that he can barely stand and fires a mouth blast at both of them. Poison Eater is about to throw them both into the poisoned lake but Yacker tries to stop him by firing missiles at him, which does no damage to the Chai.
Poison tail-smacks the alien into the lake and throws Sonic and Blaze into the water as well. Blaze wants either her parents, Silver, Manik or even Fang to save her, but she is saved by Yacker instead. Yacker drags both Sonic and Blaze into an area of water that is uncontaminated. A water spring is keeping the water pure in that area of the lake and Blaze comes with the idea of riding it to the surface using the Turtle Destruction Wave to gain impulse.
Outside the lake, Poison Eater celebrates his apparent victory and says that if he can cover Mobius with his minus fog, then the planet will become his paradise. Suddenly, Blaze and Sonic appear behind him, fully restored thanks to the water spring, and say that this time they are going to attack at full power. Poison Eater is now scared and runs towards the lake, but Sonic and Blaze fire a Turtle Destruction Wave together at the Chai, disintegrating him except for the Orange Emerald. The blackened and cracked jewel then heals itself and becomes bright and whole again. Sonic and Blaze are happy for recovering their first Chaos Emerald, but there are still six Chai left and they won't be as easy to beat as Poison Eater was.
During Sonic and Blaze's continuing quest for the Chaos Emeralds, they stumble upon an abandoned city. They are warned away by a couple that blames the mass exodus on a slime that absorbs electricity. After resolving to stay and complete their task, they find Spark Eater, the Blue Chaos Eater (born from the wish to revive Sonic during the Nikuhog invasion). They are, however, very unimpressed by his tiny appearance, not being much taller than a steel can. However, Spark Eater still boasts that his abilities are far superior to anything Sonic or Blaze can achieve. Spark Eater demonstrates his abilities with his Electric Slime, a slimy substance that can electrocute anything it is latched onto. Spark Eater then demonstrates his ability to turn himself into a titan by absorbing his energized electric slime. Sonic transforms into his Omega Hedgehog state, which angers Spark Eater. Spark Eater's electric attacks prove to be insufficient against the Omega Hedgehog, as Sonic is not affected at all. Sonic attempts to finish the fight by destroying Spark Eater and his electric slime with a 10x Turtle Destruction Wave, but surprisingly, much to Spark Eater's credit, had not only survive the attack, but his electric slime is able to conceal the energy from Sonic's attack before sending it back toward Sonic. Sonic shields Blaze from this counter move thus taking the brunt of his own attack. Sonic takes a tremendous amount damage and is forced to revert back to his child-like normal state. Spark Eater proceeds with his assault by draining the remaining amount of electricity in the city, making his electric slime grow to a massive size, making him very difficult for Blaze and Sonic to escape. Spark uses his slime to capture Blaze and Sonic and attempts to kill them both.
Unfortunately for Spark Eater, it begins to rain, inducing an explosive short circuit throughout his entire slime body. Withdrawing to a safe distance, Sonic and Blaze watch as the Chai tries in vain to scatter his electric slime again; this, however, proves impossible due to the slime's enormous surface area, which prevents Spark from taking shelter. Following the explosion of his slime body, Spark Eater returns to his original size. Sonic and Blaze find the badly injured Spark Eater amid rubble and ask that he give up. Spark Eater consented, stating that Blaze can take his Chaos Emerald, that she and Sonic had earned it. However, as Blaze reaches out her hand to take the Chaos Emerald, Spark Eater attempts to kill the young girl; Sonic promptly destroys the Chai with a close-range Turtle Destruction Wave.
As Sonic, Blaze and Yacker continue their search for the Chai, they come upon a seemingly deserted village. All is quiet until an octopus falls from the sky onto Blaze's head. Soon more fish and other sea creatures follow, prompting the men of the village to come and gather up the rich harvest. Soon afterward a skeptical young boy appears who explains that the fish are ruining the village's men, causing them to be lazy and only party all day. He mentions that all the seagulls in the area have been harmed in some way and can no longer fly; he carries one around with him, probably to keep it safe. He also explains that the food is being dropped from the sky by Princess Tethys, who is really Water Eater. The next time she appears, Yacker detects a Chaos Emerald coming from her direction. It was then that Sonic and Blaze realized that she was not who she seemed. Sonic warns the villagers and they all run for safety, this angers Water who flies up to Sonic and Blaze and reveals her name (Water Eater, the Indigo Chaos Eater)), her dominion over air and water, and that she was created when Hamlin wished for a pair of panties to foil Lord Snively's scheme, which she is very embarrassed about.
In a fit of anger she attacks Blaze and Sonic and they promptly strike back, but she deflects them without as much as blinking. She then counters with an attack that completely tears of Sonic's clothing, leaving him buck naked. Blaze screams "Grandpa, that's not cool!" and additionally blushes, with Water agreeing with her. Sonic then states that he does not mind being naked at all, to which Pan then responds by only giving Sonic another set of clothing without a single word being said. This last attack lends information to Sonic: he realizes that the secret of Water Eater's attack is in the way she spins while attacking. After Sonic informs Water of this, she transforms from a beautiful woman into a rather hideous demon. Water transforms back into the woman and says that no one who has seen her true form has ever lived to tell about it. Sonic decides to try out her spinning technique and the two continue to battle as vortexes.
Sonic lands a solid punch on her face but Water returns with an enormous gust of wind that sends Sonic deep into the cliff behind him. Sonic is being battered by the attack and it looks as if there is no way to stop it when the seagull that the boy was carrying unexpectedly flies into the eye of the tornado surrounding Water Eater and begins to attack her face. This distracts Water for a little while but not long enough for Sonic to recover and she uses the same attack again, pushing him further into the cliff wall. Blaze realizes that it the eye of the tornado, surrounding Water Eater, is the key to defeating Water, and fires a Turtle Destruction Wave into it, striking Water Eater and causing her to re-transform into the hideous demon that is her true form. Sonic seizes this opportunity to attack and uses a massive Turtle Destruction Wave that totally obliterates Water Eater and the Indigo Emerald is once more in the possession of the Freedom Fighters. The fishermen of the village express their gratitude to Sonic and Blaze and promise to work harder than ever. Blaze invites the boy to Green Hill for flying lessons when this is all over. Sonic, Blaze, and Yacker then fly off into the distance, continuing their journey to save Mobius.
Sonic, Blaze, and Yacker are flying through the air in search of the next Chai, when Yacker senses a Chaos Emerald below them. The trio land with no Chai in sight, but Yacker repeats that the Chaos Emerald is underneath them. Sonic begins to dig, but is interrupted by an earth-shaking force and tone-deaf singing. The source of both is Nature Eater, a purple mole-like creature, digging through the earth and singing (extremely poorly) about his love for causing earthquakes. At first it appears that he cannot see Sonic, Blaze, or Yacker so Sonic screams into his ear, getting his attention.
Nature is surprised to see Sonic and admits that he is "not much of a fighter", but he still refuses to give up his Chaos Emerald. He resumes his digging while Sonic tries to anger him with insults. When that fails, Blaze fires a mass of Energy Blasts at the Chai, to no avail. Nature continues tunneling, causing Sonic and Blaze to realize he is headed right toward a city. Sonic rushes off to warn the people of the city and Blaze follows suit after stuffing Yacker in her backpack. The heroes arrive just as the earthquake is starting to be felt, and they immediately go to work saving the people from certain doom.
As Blaze destroys falling rubble and retrieves trapped civilians, Sonic transforms into an Omega Hedgehog and fits the pieces of shifting earth back into place, saving the city. When Nature Eater realizes that his plan has failed, he finally attacks Sonic and Blaze with a punch. Sonic easily dodges the attack and counters with a kick to the stomach, followed by a series of blows that end with Nature being sent flying out of the city. The pureblood Nikuhog admits that Nature is a decent fighter when motivated, but Nature brags that he is "ten times the fighter you just fought" when he gets serious.
Joining the fray, Blaze wonders what wish spawned Nature, and the dragon reveals that he was created by the wish that brought back the people killed by the Shadow Android at the 25th World Battle Royale. He then attacks with his Aftershock Technique, but Blaze quickly realizes that the blasts can be avoided easily if they take to the air. This further angers Nature Eater and he fires a barrage of Aftershocks at Sonic and Blaze, which they easily dodge before landing on the monster's head, frying him with his own attack. Sonic and Blaze easily evade the blast (with the former returning to his normal form), and Blaze admits shock that Nature fell for "the oldest trick in the book".
Lamenting the humiliation of beating himself, the charred Chai falls to the ground and explodes, sending the Purple Emerald into the waiting grip of Blaze. Suddenly, the still-corrupted gem turns into a jewel of blue light, sucking Blaze into itself. Despite Sonic's efforts, Blaze is absorbed by the gem, which swells and transforms into Nature Eater, but bigger, bluer, and more demon like than before. The Purple Chaos Eater laughs at Sonic, explaining that he was tricking them the whole time. He reveals that he had taken over the body of a mole until the heroes defeated him, allowing him to use his Chaos Emerald to possess Blaze's body. With his power exponentially increased with his new host, Nature attacks Sonic, intent on wearing out his current body before possessing an Omega Hedgehog.
Nature Eater's secret has come out: the Chai can possess another body and take on the powers of whomever he possesses. After the Chai takes control of Blaze, Sonic is forced to make the most heart wrenching decision of his life. The shot to possess the Chaos Emerald lies directly through his granddaughter. Sonic transforms into an Omega Hedgehog after Nature Eater hurts people. Nature panickly reminds him that he will also kill Blaze, and he notices the Nikuhog hesitate, and mocks him for it. Realizing Blaze would rather die than see more people get killed, Sonic unleashes a Turtle Destruction Wave on Nature. However, the blast does not have enough energy to kill him because Sonic realizes that Blaze is still inside of him, causing him to subconsciously hold back.
Sonic begins to give in, rapidly losing energy as he is beaten and blasted, and is eventually knocked onto a nearby roof. Nature gets cocky and claims that he is the most powerful out of his brothers and will be the one true Chaos Eater. He starts using some of the Chaos Force's classic lines, such as "What is your wish?" Sonic does not answer him, and suddenly closes his eyes. Thinking that he has won, Nature taunts Sonic by partially releasing Blaze from his stomach. The young girl tries to convince her grandfather to fight, but her pleas are seemingly in vain. Tiring of his game, Nature begins to reabsorb Blaze, stating another Chaos Force quote ("Your wish... has been granted") in the process. Suddenly, Sonic wakes up, grabbing Blaze and pulling her out of Nature. At this point, Sonic reveals that he deliberately held back with the Turtle Destruction Wave and allowed Nature to beat him up to make the Chai confident enough to taunt him by partially releasing Blaze, giving Sonic the opportune moment to remove his granddaughter from the demonic Chai's body.
With Blaze gone, Nature reverts back into his true form: a small brown creature whose head is barely larger than the Chaos Emerald on his scalp. It is revealed that Nature himself is very weak; the only way to increase his power is to absorb another living thing. Desperate, he tries to absorb a bird, but Sonic blocks his path, berating Nature off for harming others. Nature tries begging for mercy as a ploy to lower Sonic's guard (similar to what Spark Eater did against Blaze), but his Energy blast does not even faze the Omega Hedgehog. Sick of Nature's dirty tricks, Sonic brutally beats up the diminutive Chai and kills him with a 10x Turtle Destruction Wave.
With four Chaos Emeralds safely in their possession, Sonic and Blaze set off in search of the fifth. Standing in their way is the incredible Flame Eater, the Green Chaos Eater (created from King Knuckles wish to return to his youth), which Blaze meets and attacks while she is alone, but Flame Eater knocks her out. Sonic and Flame start to fight. Sonic quickly learns that his hand will burn off if he punches him and that he will lose his toes if he kicks him because of Flame Eater's ability to make his body reach temperatures higher than even the Sun. When Sonic and Flame go back outside during their battle, Sonic learns that Flame gets his energy from the Sun and that it never runs out. Sonic hits him with a Fist of the Sun. After that, Flame powers up to his second form and Sonic powers up to Omega Hedgehog.
Through the years Shadow, Prince of Nikuhogs, was forced to bear the burden of being second best to Sonic. Though Shadow and Sonic set aside their differences many years ago and became friends, Shadow once again recalls the bitterness towards Sonic that was once within him. He remembers how when he first met Sonic, and that he did not think he could be beaten by a lower class Nikuhog, and yet he was. Then he recalls all the times he surpassed Sonic, only to have Sonic find a higher level and surpass him once again. Shadow begins to question whether it is his destiny to always be second best.
After straightening his thoughts out, Shadow grabs a soda and heads out to see Rouge, who is working on her computer. They watch a replay of the battle between Sonic and Shadow (when the latter was possessed by Juvie) and make an astonishing discovery: a way for Shadow to reach the same power as Sonic, Omega Hedgehog. Rouge even begins to joke that Shadow could reach "a fifth level of Super Hedgehog", but first they make it a goal to have Shadow reach Omega Hedgehog and finally be even with Sonic.
As Sonic and Flame Eater continue their fight, after Flame manages to outrun Sonic's Turtle Destruction Waves, Sonic manages to trick Flame in an abandoned building and corner the Chai. With Sonic winning his battle against Flame Eater, he spares the dragon's life in exchange for not killing Blaze when he had the chance. But things get complicated when Ice Eater, the Yellow Chaos Eater (born from the wish to remove the memories of Mephiles) shows up to reveal a shocking secret that no one saw coming.
With the odds stacked against him, Sonic fights for his life against the terrible twosome. During the battle, Ice Eater uses his Ice Rays to freeze Sonic's limbs one by one, starting with his arms. After Sonic shows he can still fight well with just his legs, Ice freezes those too, eventually freezing up his entire body. When Ice is finished, he orders his brother Flame to finally finish off Sonic. Flame however, only melts the ice off of Sonic's body with his Nova Star technique, much to his brother's frustration, and thus Sonic continues to battle the meddling Ice Chai once again.
Having encased the entire city in ice, Ice Eater begins his fight with Omega Sonic, agreeing to give him five seconds to defeat him (the only time Ice even plays fair). After pummeling him into the ground, Sonic is about to finish Ice off, but Ice finds an unconscious Blaze, and uses her as a shield, causing Sonic to drop his guard. Ice takes the opportunity to throw Blaze at him, who catches her, and then kick him while he's down and defenseless. This, however, does not last, as Sonic grabs hold of Ice' foot, and gets right in the Chai's face about having used his granddaughter as a shield before throwing him into another building. Sonic then prepares another finishing Turtle Destruction Wave, but then Ice flies around Flame Eater, using him as a shield to get Sonic to drop his guard once again. Ice takes advantage of Sonic's guard being down and freezes him in ice again. After being berated by his brother for such cowardly moves, Ice is about to destroy Sonic with his Chaos Blast (don't ask me how he learned that), until Sonic successfully breaks free from the ice, and stops Ice' energy beam dead in its tracks.
Still furious at Ice for using both his granddaughter and Flame as shields, Sonic threatens to kill the cowardly dragon at point blank range, until Ice begins to beg for his life, and even offers up the corrupted Chaos Emerald. Flame is even respectful enough to advise Sonic to just take the Chaos Emerald from him, rather than killing him. Sonic agrees and orders Ice to give up the Yellow Emerald, leave, and never show himself again. This is all just an act however, as Ice discretely digs his fingers into the ice, forms Ice Blades on his fingers and swipes them across Sonic's eyes, blinding him. Ice is about to finish him off, but even Sonic's blindness does not stop him, as he makes use of his other four very sharp senses and impales Ice through the chest with his fist. Sonic finishes him off with the mighty Rolling Explosion Fist.
While washing his eyes out in a feeble attempt to reverse his blindness, Sonic is given an antidote by Flame Eater, which will restore his sight. Flame explains to Sonic that, unlike Ice, he has respect for a fair fight, and will return once his eyes are healed. However, Flame is shot in the back by an energy beam, which also shatters the antidote Sonic was holding. The stranger steps out of the shadows to reveal himself to be Sin Eater, the Red Chaos Eater (born from the wish to revive everyone killed by Eggman and his followers), and the most powerful Chai. Disgusted by Flame's mercy towards Sonic and having given him an antidote, Sin fires another blast, aimed at Sonic. Flame hurls himself in front of Sonic, fatally taking the energy blast. Before he dies, Flame apologizes to Sonic, saying he wanted to settle their fight fairly. Enraged, Sonic gets up, ready to fight. Disregarding Sonic's outrage, Sin condemns him by reminding him that it was his fault that the Chai were born, due to overusing the Chaos Emeralds.
The fight begins, with Sin having the upper hand. Despite the power of the 10x Turtle Destruction Wave, Sonic is no match for Sin, who fires his own energy ball at Sonic, which tracks him wherever he goes, until he is hit head on and launched into a building, barely holding onto a metal rod by his pant cuff. Blaze, having regained consciousness, sees her grandfather in danger and calls for help. Is there any hope for Sonic now?
After a panicked call for help from Blaze, the Freedom Fighters descend on the battleground in a frenzy, saving Sonic at the last minute. While the brutal Sin Eater continues his assault, Sonic works up a long shot of a plan. It is going to take everyone's cooperation to pull this one off, and even that might not be enough and could end up killing him from giving him too much energy.
While the Nikuhogs give Sonic their power, Philmes fends off Sin Eater. Although it is clear Philmes is no match for the Chai, he is able to annoy him long enough for Sonic to boost up his energy level. When Sonic begins to fight Sin Eater as an upgraded Omega Hedgehog, it is shown that Sin Eater is no match for him anymore.
Desperate, Sin Eater does a last ditch effort to ensure his victory: He eats the Chaos Emeralds. After ingesting the Chaos Emeralds, the ultimate Chai, Time Eater was born. Blind and battle weary, Sonic can barely stand against the might of all seven Chai in one. To push Sonic to fight better, Time attacks his family and friends (consisting of his sons, wife, daughter-in-law, Fang, Philmes, and Silver). As expected, Sonic tries to land his best attacks on Time, but to no avail. He eventually regains his vision, much to Time's surprise, but even the return of his eyesight does not help him gain the upper-hand against Time.
Becoming more desperate to save his family and Mobius, Sonic decides to self-destruct himself. He grabs a hold of Time from behind and almost completes the technique before Shadow arrives and tells him not to do it; having firsthand experience with self-destruction, he knows Sonic will only succeed in killing himself and not Time. Shadow then tells Sonic that he has the tool he needs to reach Omega Hedgehog, much to Sonic's shock. Thanks to Rouge's Blitz Wave Generator, Shadow transforms into a Werehog.
At first, Shadow seems to have lost control of himself and begins crushing Sonic. However, Sonic states that he was simply fooling them and transforms into a Golden Werehog, and then an Omega Hedgehog. Everyone is amazed by the overwhelming power the two Omega Hedgehogs have, and Sally and Rouge have a usual quarrel over whose husband is the best. The two Omega Hedgehogs head off against Time Eater, but they are still not powerful enough to beat the fearsome dragon. So, Shadow suggests that they fuse, much to Sonic's surprise that Shadowa would suggest it in the first place, and pull out a pair of Secret Rings.
With Time Eater still too powerful even for two Omega Hedgehogs, Sonic and Shadow decide to perform the Secret Ring Fusion. Time seems more excited that he will get to fight two Omega Hedgehogs and moves in for the attack. However, Silver, Charlie, and Manik move in to stop him and buy their fathers time to fuse successfully. Shadow tells Sonic they need to hurry and fuse, but Sonic watches with pride as his and Shadow's sons fight together.
As the Half-Nikuhogs are defeated, Sonic and Shadow finally fuse and become the incredible Omega Darkspine. Although he is baffled by the technique and remarkable increase of power in Darkspine, Time still proclaims himself the strongest. However, the tables turn as Time Eater suddenly cannot seem to land a blow and Darkspine is not even working up a sweat. Darkspine might just save the day (if he can stop joking around for long enough, that is). The reason for Darkspine's stalling was to wait for his opponent to charge up his Time-Space Bomb, Darkspine then transmits some of his own energy through it, causing a change from negative to positive energy. This frees Mobius of the negative barrier that was interspersed around it by the Chai. Darkspine may have had his laugh, though: he performs his Chaos Destruction Wave on Time Eater, obliterating him, which causes the Chaos Emeralds to get out of Time Eater. The Chai manages to regenerate, but now it seems that he is near defeat.
Omega Darkspine charges up his incredible Chaos Destruction Wave once more to finish off the Chai, however at the very moment, the Secret Rings shatter from the enormous power and the fusion ends, and Sonic and Shadow separate. Shadow is angry and says that they have been fused forever, and demands an answer from Sonic. Sonic says that it might be that they are not used to the powers of two Omega Hedgehogs combined and that was too much for the Secret Rings to handle. Now, with the fusion cut short, Sonic and Shadow are again powerless to stop the Chai. Time tries to reclaim the Chaos Emeralds, but Sonic intercepts the last one, the Green Emerald, because it reminds him of Uncle Chuck. Time will not give up on getting it back, and seems happy that the Nikuhogs are at his mercy now.
Sonic and Shadow try to regain their winning form by doing the Fusion Dance, and Time Eater tries to regain his by ingesting the Green Emerald. Sonic eats the gem to prevent Time from reclaiming it and nearly chokes to death before swallowing it. Time says that he will have to kill Sonic to get it, but Shadow will not let that happen and tries to attack, but is unable to land a hit on him. Sonic also is unable to touch him, but manages to cause some pain to Time by spin dashing him on the back of the Chai's head.
Sonic later gives Time Eater a lecture how that people who are bad are scared because they know their lives can be taken away easily and that they must be good if they want good things to happen to them. Time brushes it off, and Shadow says that he himself had to learn the hard way and that Time should listen to Sonic, but Time Eater ignores them and throws them around like toys. Shadow is baffled that Time is making a joke out of two Omega Hedgehogs, which is the peak of the legendary Nikuhog transformation (aside from Holy Hedgehog). Sonic and Shadow try several times to fuse as a last resort, but Time Eater eventually realizes what fusion is and is trying to stop them because he knows he will die if they manage to fuse again.
Sonic and Shadow come up with a confusing technique; they create duplicates of themselves, that will allow them to fuse while Time Eater cannot tell which of the duplicates is them. They manage to perform the dance, but they do not fuse; Shadow asks why and Sonic says it could be that Shadow did not extend his index fingers (which is not true). Silver thinks that it could be because Sonic is out of power due to his long battle against Time. Time, realizing this, tells Sonic and Shadow that they can give it another try. Unfortunately, in this try, Sonic reverts back to his child form, much to everyone's horror. Time is prepared to move in for the kill until the Green Emerald appears on Sonic's forehead.
Sonic does not realize that the Green Emerald has appeared on his forehead, even when Shadow gives him an obvious hint, until Blaze tells him to feel his forehead. Time Eater decides to retrieve the Chaos Emerald while killing Sonic and moves in for the kill. Then, the Chaos Emerald starts glowing and flies in between Time and Sonic, revealing to be Flame Eater. Sonic is happy to see him, but Flame is cold and speaks with Time, who tells him to kill Sonic. Flame seems excited and tells Sonic that he will not be merciful. Shadow attacks Flame, but the Chai is too fast for him and blasts him away. He then attacks Sonic, who cannot land a hit on Flame.
Silver checks on his father, who is unharmed. Shadow realizes that Flame is fooling them and was not trying to hurt him and Sonic. His suspicions are confirmed when Time tells Flame to finish Sonic off so he can fight someone better, and Flame and Sonic attack Time together. Time says that Flame should have been charged up with full negative energy, but when Sonic swallowed the Green Emerald, some of Sonic's positive energy was passed into Flame. Flame binds Time and traps them in a fire ball, where Flame plans to burn and destroy Time himself.
When the ball explodes, Flame appears and it seems that it' over. However, Flame breaks apart and Time reappears; he says that he forced the six Chaos Emeralds into Flame, moving himself into Flame's Chai body. He now has all seven Chaos Emeralds and is as powerful as before. Shadow tries to power up, but reverts back to his normal form, because the Blitz Wave Generator has been destroyed. With Sonic and Shadow in their normal forms, they are at Time's mercy.
Growing bored with Sonic and Shadow's bickering, Time unleashes a Time-Space Bomb, intending to destroy Mobius with it.
Sonic steps in and holds it at bay with all his might. While struggling against the minus energy, Sonic comes to understand that Mobius has suffered far too much for too long because he and his friends abused the power of the Chaos Emeralds, and pleaded for the strength to defeat Time and in return, he and his friends will survive from now on without using them. The Negative Energy is too much for Sonic, and eventually explodes, leaving a city-sized crater in Mobius. Everyone assumes that Sonic was killed in the blast and mourn him. Time Eater summons negative energy to destroy various parts of Mobius. Growing more desperate to save Mobius, Shadow immediately orders Silver, Charlie and Manik to get the remaining people as far away from Mobius as possible while he fights Time as long as he can, and to continue the fight if he cannot. The Half-Nikuhogs get their families far away only to say goodbye to them, and return to fight to the last by Shadow's side, which expectedly, is to no avail. Just when it seems to be the end, Shadow notices something in the crater; Sonic is alive and building up the last hope of the universe: the Soul Blast.
Since Sonic used all of Mobius's energy to make the Spirit Bomb, he knows it is not going to be enough to destroy Time, so he calls King Lazaar and asks him to call everyone in the universe and ask them to give him their energy. Sonic successfully obtains all of the energy he needs, and after thanking everyone in the universe for their help, he throws the Universal Soul Blast at Time Eater, who is engulfed and destroyed in its path. With the Chai gone, the Chaos Emeralds return to normal, but then, all of a sudden, the original Chaos Force, without being summoned, appears before everyone.
The Chaos Force then heals Sonic, and informs him and the other Freedom Fighters that he will not be able to grant any wishes for a long time due to everything that has happened involving the Chaos Emeralds with its negative energy, but Sonic asks him if he will grant just one for "old times' sake". He asks the Chaos Force if he can bring everyone that died at the hands of the Chai and Super Jet back to life. The Chaos Force grants the wish. Everyone begins to worry that Sonic is leaving them again.
The Chaos Force asks Sonic if he will come along and Sonic climbs on the Chaos Force's back. After Sonic climbs on, a crestfallen Shadow runs over and asks Sonic where he is going. A moment later, Shadow realizes that Sonic is going to train with the Chaos Force and help fulfill this wish. Before going, Sonic tells Shadow that he is now Mobius's protector, and tells him that everyone is in his hands now. Sonic and the Chaos Force go flying, and the Chaos Emeralds begin circulating around Sonic. Sally tells Sonic to be home in time for dinner, but Sonic and the Chaos Force fly off.
Charlie, Mina, and Sally return to their homes. Manik and Charlie try to comfort Sally by telling her that Sonic always comes back for dinner. Blaze asks Silver if the Chaos Emeralds will ever come back. Silver talks to Blaze about the Chaos Emeralds, and is confident that they will again come back one day. Then Blaze looks worried, and she stumbles upon Sonic's fighting uniform. Shadow comes and tells her to take good care of it. Shadow then flies off, leaving Blaze alone. Blaze, with tears in her eyes, wonders if Sonic will ever come back during her lifetime.
Sonic asks the Chaos Force to stop a moment at Turtle House to see Tails, who was newly revived. They start talking about the past and end up having a little play fight. Tails wins and then Sonic disappears. Then The Turtle Hermit thanks the Chaos Force for the Chaos Emeralds. Sonic also visits Knuckles, who is now in Hell keeping watch over everyone there. Sonic tells Knuckles that he will get out of Hell someday and then leaves without saying goodbye. Many people see Sonic with the Chaos Force, including Vector and Nicole who seemed like they were fixing their car, as well as Espio and Charmy, who are busy training.
Sonic goes with the Chaos Force and lies on his back. The Chaos Emeralds enter Sonic's body, and the Green Emerald goes into Sonic's heart (this is symbolic, because the Green Emerald has always represented Uncle Chuck to Sonic). The Chaos Force roars, and then he and Sonic vanish into another dimension.
