Dimension Obliteration

Dimension Obliteration is the sequel to the Youtube crossover series Dimension Takeover. Obliteration, like the previous two installments in the Dimension Saga, was created by the youtuber thechocobro as well as a crossover between Calvin and Hobbes, Sonic, and Invader Zim. Dimension Obliteration picks up where Dimension Takeover left off. The heroes have once again gone their separate ways and resume their normal lives, but are oblivious of the rise of a new villain from the darkness, and the heroes must reunite again to stop the villain before he puts his plan into effect. The series so far has 14 parts since its introduction on May 21, 2012 and is still not complete. Thechocobro has promised, however, that they have not abandoned the project and that they intend to finish the trilogy.
==Sypnosis==
A number of months have passed since the Xevian Invasion and the defeat of Tak and GAMP. Earth is now peaceful again and has recovered from the Xevian Invasion. The heroes have once again gone their separate ways to resume their normal lives while also struggling to overcome the trauma of tragedies they suffered during their adventures in Mix-Up and Takeover (Shadow's disappearance, Dib's sacrifice, and Zim's departure from the heroes to assassinate the Almighty Tallest upon learning of the leaders' treachery). However, as the heroes struggle to cope with their losses, they are oblivious of a new threat as a new villain rises from the darkness. As the heroes slowly come to terms of this new threat, they realize that they must team up again in order to save Earth once more. However, this new villain is far more dangerous than any villain the heroes faced before, and his plans may threaten all of reality. In a race against time, the heroes must rejoin forces to stop the villain and save the world, or else their new menace will send all of reality on the path to oblivion...
==Plot==
It has been months since the Xevian Invasion and peace has been restored on Earth. The heroes have once again gone their separate ways and resumed their normal lives while struggling to cope with the sacrifices of Dib and Shadow during the events of Mix-up and Takeover. They are also coping with Zim's departure from the group to hunt down the Almighty Tallest, the leaders of the Irken Empire, whom Tak revealed were using Zim as a pawn to conquer Earth at the climax of Takeover. The story begins showing flashbacks of many major events during Mix-Up and Takeover (Destruction of the Death Egg, defeat of Dr. Eggman, Tak's revelation of the Tallests' corruption and treachery, etc.). The story then cuts to the present day, on the planet that appeared at the end of Takeover as the robot Omega treks the planet's rocky terrain, heading for the crash site. The screen then cuts to Earth, in Calvin and Hobbes's hometown, Calvin is released from school on a Friday afternoon. As Calvin is about to walk out of the door, Moe, a bully and enemy of Calvin, begins taunting Calvin to extort money from him. Calvin warns him to back off, but Moe refuses and attacks Calvin. Calvin quickly retaliates with a brief fight and runs out the door before Moe can punch him. Moe attempts to pursue, but is grabbed by Calvin's teacher and taken to the principal's office. Susie, who was observing the fight Moe instigated, tells the teacher that Calvin is struggling to cope with the loss of Dib during the Xevian invasion months earlier. The teacher quickly understands and thanks Susie for telling her the reason behind Calvin's recent mood swings. Meanwhile, Calvin is walking home through a snow covered sidewalk. Calvin experiences a flashback of when Dib gave Calvin his watch during the heroes' battle against the Xevians at the Nazca Lines. After the flashback, Calvin continues walking home. Meanwhile, in outer space, the Irken armada led by the Massive, the Irken flagship, fly through space over planet Blorch, the planet that appeared at the end of Takeover. Onboard the Massive, the Almighty Tallest discuss the lack of progress they have made in their conquest of the galaxy and their shortage on snacks. An Irken operative named Skoodge contacts the Tallest about the ship that crash landed on Blorch at the end of Takeover. In response, the Tallest send Skoodge to investigate the wreckage. The Tallest are shocked to learn that the ship had debris from the Death Egg. However, just as the Massive approaches Blorch, a small ship emerges from the darkness of space, the same ship Zim used to reach Xevious and escape from it with Sonic at the climax of Takeover. Zim's ship opens fire on the Massive and Tallest Red orders the fleet to return fire. When an Irken soldier reveals that Zim is piloting the ship, the Tallest freak and order the rest of the ships to open fire. Zim proceeds to destroy most of the Irken ships. Zim eventually crash lands in the docking bay of the Massive and makes his way to the bridge. The Tallest also notice Zim cutting their power and flee the Massive's bridge. The Tallest order their Irken soldiers to disperse across the galaxy and hunt down Zim. Zim boards the bridge of the Massive and attacks a squad of Irken soldiers. He kills all the soldiers save for one, whom the ex-invader questions of the Tallests' whereabouts. The soldier refuses and Zim kills him. The Tallest rush to an Irken derelict ship and blast out of the Massive. Zim quickly gains control of the Massive's systems and notices the Tallests' ship flying away. Zim begins firing the Massive's laser cannon at the Irken ships and destroys more of them. Zim manages to scratch the top of the Tallests' vessel. Tallest Purple freaks out about Zim taking over the Massive so quickly, but Red reassures him that Zim is more dangerous than ever as he is now aware of their lies. Red tells Purple to set random coordinates for hyperspeed, which Purple desperately does. Meanwhile, the remaining Irken fighters retreat and disperse. Zim prepares to blast the Tallests' ship to oblivion, but Purple jabs his finger into the hyperspeed button and the Tallest escape. Zim vows that the hunt has just begun and will bring the Tallest to justice. Meanwhile, the Tallest discuss how they narrowly escaped Zim and hope to find a safe haven until their troops capture or kill Zim. Red asks where Purple had set the coordinates for, but Purple begins suffering from paranoia as a result of Zim's attack. Purple also reveals that he set the coordinates for Luna, Earth's moon. The ship then blasts off, heading for Luna. Meanwhile, on Blorch, Omega reaches the crash site and finds Shadow, who disappeared after his sacrifice to destroy the Death Egg. Meanwhile, on Earth, Sonic is experiencing flashbacks of his adventures in Mix-Up and Takeover. Amy comes along and asks Sonic what is going on. Sonic replies that he was thinking about Dib and their adventures in the previous series. Sonic has also found himself questioning why everything happened at all and blames himself for Dib and Shadow's sacrifices. Amy comforts Sonic, saying that neither of the sacrifices were his fault and that the ones to blame are the people who caused the grief themselves. The two hedgehogs sit together and watch the clouds. Meanwhile, at the house of the late Dib, Professor Membrane, Dib's father, finds his daughter Gaz sitting on Dib's bed. Gaz tells her dad she is thinking about her deceased brother. Membrane then leaves Gaz be and enters his laboratory. Membrane replies "remarkable", indicating he has discovered something. Meanwhile, the Tallest land on Luna and set up a temporary base of operations there. Meanwhile, on Blorch, Shadow and Omega reactivate the e-series robots, who were Omega's production line. Omega then questions Shadow about the current situation of the universe. Gamma, one of the e-series robots, calculates that the stability of the universe is on overload. In response, Shadow orders the e-series to double their efforts in repairing the crashed ship to escape Blorch and return to Earth, where Shadow says a new danger has arisen. Shadow tells Omega that while the heroes were searching for the chaos emeralds five years ago, there was an attempt to seize the stability of the universe and now, stability is about to reach a breaking point. Shadow also reveals that a being seeks to obliterate all of reality. Shadow explains that while he was searching for the chaos emeralds with the other heroes, he constantly felt a surge of disruption in time and space, and decided to investigate the cause of the disruptions. Shadow grew tired of the group's arguing and decided to look for the cause on his own. After traveling through Earth for some time, Shadow discovered that someone on Earth was indeed responsible for the disruptions in time and space. However, Shadow was unable to determine the identity of the culprit. The villain's disruptions of time also forced another e-series robot, Beta, to scatter the chaos emeralds across Earth to keep them protected. Shadow went to the Death Egg with Omega to liberate the other e-series robots and disappeared after liberating them. Shadow later resurfaced on Blorch and is currently attempting to repair the ship so that he, Omega, and the e-series can use it to return to Earth and stop the villain before he puts his plan into effect. Shadow then looks into the stars and comments that it will not be long before the villain makes his next move and questions whether everyone else on Earth will be prepared when the time comes. Meanwhile, on Earth, Calvin is shoveling the snow on the sidewalk leading to his house. As he is shoveling, a snowman like monster Calvin has dubbed a "snow goon" emerges from the snow and proceeds to stalk Calvin. Calvin turns around and sees the snow goon, but not before it takes the form of a normal snowman. Calvin instantly realizes that this snowman is not of his making and dismisses it as Hobbes playing a prank on him. When Calvin's back is turned, the snow goon reverts to its normal form and attacks Calvin, and he quickly comes to the realization of the snow goon's return. At first, Calvin is driven back by a barrage of snowballs hurled by the snow goon, but quickly gains momentum and decapitates the snow goon. The headless snow goon prepares to attack, but Calvin grabs his snow shovel and destroys the snow goon. However, more snow goons emerge from the snow and advance towards Calvin. The snow goons attack and one of the snow goons grabs Calvin while another snow goon breaks Calvin's snow shovel in half, much to Calvin's shock as they have twigs for arms. Before the snow goons can get their revenge on Calvin for defeating them in his imagination, Hobbes busts outside and destroys the snow goon holding Calvin by pouncing on it. The snow goons continue to advance on the duo. When Hobbes asks how to defeat the snow goons again, Calvin tells Hobbes they defeated them in Calvin's imagination together by freezing them with the garden hose, but Hobbes wonders if the snow goons are expecting that. Calvin and Hobbes make a break for the garden hose to freeze the snow goons again, but the hose is dehydrated and does not work. With the snow goons advancing on the duo again, Calvin tells Hobbes to hold off the snow goons while Calvin goes around the house to see if the backyard hose still works. Hobbes keeps the snow goons busy while Calvin runs to the backyard to find the backyard hose. However, two snow goons block Calvin before he can reach the backyard hose, but one of them is hit by a water balloon thrown by Susie, who wants to help Calvin stop the snow goons. Calvin destroys the frozen snow goon and goes with Susie. Calvin and Susie hear Hobbes telling Calvin to hurry up and the two head back to find Hobbes in a standoff with the other snow goons. Susie is also shocked to learn that Hobbes can revert from a stuffed animal to a real tiger. With the snow goons advancing, Calvin, Susie, and Hobbes use water balloons to freeze the snow goons and then shatter them while they are frozen. The trio use almost all of the water balloons in their possession to destroy all of the snow goons until only the two headed alpha snow goon is left. Calvin throws a water balloon at the alpha snow goon and freezes him. Before Calvin can destroy the frozen dead alpha snow goon, the alpha snow goon disappears and Illusions of aliens from Calvin's mind appear to kill the trio. The trio flee inside Calvin's house. Calvin barricades the door, but the aliens break through. Meanwhile, onboard the Massive, Zim has improved the Massive's systems and computers in order to aid him in tracking down the Tallest. Zim questions the Tallests' whereabouts just as he re initiates his hunt. Meanwhile, on Luna, the Tallest are discussing Zim's previous assassination attempt on the Tallest with a small group of Irken soldiers that escorted them during their escape from the Massive. The Tallest eventually come to an agreement to train the Irken soldiers in the event that Zim finds them to kill Zim. Meanwhile, on Earth, Calvin, Hobbes, and Susie are holed up in Calvin's house as the alien illusions attempt to break into the house. The lead alien taunts Calvin, saying there is nowhere he can run where the aliens cannot find him. Calvin, Susie, and Hobbes run upstairs as the aliens quickly break in. They are stopped by Calvin's mother, who is apparently oblivious of the chaos and tells Calvin to prepare for dinner. However, a piece of debris falls on Calvin's mother and phases through her, exposing her as a hologram and she disappears. Before Calvin can question this strange phenomenon, the aliens finally locate the trio. As the aliens charge at the heroes, time freezes around Calvin and he is confronted by a mysterious figure, who is revealed to be the villain Shadow had mentioned earlier, unknown to Calvin. When Calvin questions the villain's purpose and where his parents are, the villain tells Calvin that his parents were non existant and his hometown is not his hometown. The villain claims that Calvin's hometown is home to those who never understood him or accepted his brilliant mind. The villain tells Calvin the reason for his alienation is because he does not belong in his hometown and that he should be somewhere else. Calvin questions why he has spent his whole life in his hometown if the villain is indeed telling the truth, but the villain rebuffs, saying Calvin will understand when he reaches his "destination". The villain also claims to Calvin that the aliens from his mind are trying to prevent him from returning to his "real home". The villain warns Calvin the illusions will pursue him if he escapes the house, but they will not be able to attack Calvin or his friends once he reaches his "real home". The villain reveals the disruption of stability in the universe, but leaves his role of instigating the disruptions out. He also tells Calvin that because of the disruptions, the monsters that were mere figments in Calvin's mind have become part of reality. The villain also claims that once Calvin reaches his "real home", everything will be right again. Calvin asks the figure if he can trust him, but the villain apologizes and tells Calvin that he has no other choice and disappears. With the villain's departure, time unfreezes and the aliens resume their attack. The aliens corner the trio and demand they give up Calvin. Calvin steps in front and asks the aliens to capture him. As the lead alien advances to capture the hero, Susie throws a bomb and subdues the aliens. The trio run to Calvin's room and barricade themselves inside. Once the door is locked, Calvin shuffles through his desk looking for something. Calvin quickly finds the object, revealed to be Dib's watch, which Calvin has had in his possession since Takeover. The aliens return to their senses and quickly attempt to get in to Calvin's room. Before the aliens can open the door, Calvin activates Dib's watch and teleports Hobbes, Susie, and himself out of the house. Meanwhile, in Dib's house, Membrane figures out about the disruptions in the universe's stability. Realizing the danger the disruptions pose, he immediately alerts Gaz of the situation. Meanwhile, Sonic's friend Tails finds a message on his computer reading "Danger: Overload". Meanwhile, on Blorch, Omega detects a life form in the wreckage and informs Shadow of it. Meanwhile, on Earth, Gaz questions the meaning of Membrane's discovery, and Membrane tells his daughter that the universe has lost stability and that every part of reality is in danger of oblivion, including Earth. When Gaz questions what is causing the disruptions, Membrane replies that he does not know, but there is no denying that everyone on Earth is at risk. At the same time, Tails realizes that the message is referring to the disruptions and runs off to warn Sonic. Meanwhile, Membrane deduces that an unknown figure is causing the disruptions and promises to find him. Gaz volunteers to go with her father, but Membrane refuses, saying that he has already lost Dib and he cannot bear to lose her too and leaves. Meanwhile, on Blorch, Shadow, Omega, and the e-series find a reptilian named Swampy, who pulls himself out of the wreckage and attacks. Shadow immediately subdues Swampy and reveals to Omega and the e-series that he is in league with the unknown villain. Shadow interrogates the reptilian about the identity of the villain and his intentions, but Swampy refuses to tell Shadow anything about the villain or his plans. Meanwhile, on Luna, the Tallest have trained their Irken soldier escorts to capture and neutralize Zim. However, the Tallest fail to notice that GIR, Zim's robot sidekick who was left behind on Earth, is spying on them. Zim locates the Tallest through GIR's observations and dispatches a squad of SIR robots to deal with the Irken soldiers and the Tallest. Meanwhile, on Earth, Moe is walking down a sidewalk when he is surrounded by the alien illusions. They question Moe on Calvin's whereabouts. Moe refuses and says he doesn't know where Calvin is.  Meanwhile, Calvin, Hobbes, and Susie find themselves on the island that Shadow teleported the heroes to during the climax of Mix-Up. Upon arrival, the three heroes begin running towards the forest on the island, but when Hobbes questions Calvin where he is going, he replies that he has no idea. Meanwhile, the squad of SIR units arrives on Luna and begin their hunt. Just as Purple goes back inside the Tallests' hideout, the SIR robots attack in an attempt to kill Red. Despite their best efforts, they are fought off by the Irken soldiers. Zim also sees this through GIR and teleports the SIR squad back to the Massive for repairs. GIR also escapes with the SIR robots to further aid Zim in defeating the Tallest. After the SIR robots retreat, Purple comes out of the hideout and Red informs him of the attack. Red also tells the ever paranoid Purple that although they survived the attack, Zim now knows of their location and they must have Zim hunted down and killed. Meanwhile, on Earth, Gaz finds Dib's ship in the house's garage and activates it and flies off, thus going against Membrane's wishes for her to stay out of the conflict. Meanwhile, Sonic, Tails, Knuckles, and Amy are discussing Tails's discovery of the universe's instability. Tails informs Sonic of the message on his computer and tells Sonic, Knuckles, and Amy that although he does not know what is causing the disruptions, the problem needs to be fixed soon. Knuckles notices Dib's ship landing on the island the four heroes live on. Gaz emerges from the ship and asks Sonic for help. Meanwhile, on Blorch, Shadow is unable to get any information out of Swampy. Omega suggests that they kill Swampy to prevent him from furthering the goals of the villain, but Shadow tells Omega that Swampy is their only link to the villain. The e-series find a teleporter in the wreckage, but before Shadow can activate the teleporter, Skoodge arrives and tells the heroes that a barrier (the force field surrounding Earth activated by Sonic in Takeover) is surrounding Earth and they cannot return. Skoodge also reveals Zim's mission to eliminate the Tallest. Skoodge also reveals that he was ordered to investigate the crash site by the Tallest, but lost contact with them after they reached Luna. Omega detects the barrier and tells the heroes their chances of penetrating it are unlikely. In response, Shadow tells Omega to locate and trace the source of the barrier and find a way to disable it. Shadow also tells Skoodge to re-establish contact with the Tallest. Shadow also tells the e-series robots to resume repairs on the ship so in the event that the teleporter is destroyed, the heroes will have an alternative way of returning to Earth. Meanwhile, on Earth, Calvin, Hobbes, and Susie make it to the other side of the island where the forest meets the ocean. Hobbes asks Calvin what the big deal is with him. Calvin tells Hobbes and Susie of his encounter with the villain. When Hobbes questions Calvin on when the conversation happened, he tells Hobbes that the villain froze time around him so he could speak to him privately. Hobbes believes that Calvin is making up an excuse to escape from his normal life, but Calvin tells Hobbes that his mother was a hologram and that if he were lying about his false upbringing, he would have hallucinated his mom disappearing. Hobbes realizes that Calvin is indeed telling the truth, but implies that the villain was making it up, but Calvin remains unsure. Calvin also reveals the disruptions in the universe which is causing mere figments of his mind to become reality, and that the only way to fix it is to return to his "real home". Before the trio can continue, Susie is attacked by a Tyrranosaurus Rex, which is also another figment of Calvin's mind with the villain watching the events from his headquarters. Professor Membrane then enters the room and deduces the villain to be responsible for the disruptions and was revealed to have been using his security cameras to get information on the villain, including his tricking of Calvin. Membrane tells the villain that by erasing reality he is putting innocent lives at risk and he risks killing anything that lives, including himself. Membrane calls the villain insane, which the villain relates to Dib and reveals that Gaz has gone to Sonic. Meanwhile, Gaz reveals that she thought Sonic might understand hat's going on, but Tails tells Gaz they do not know much more than Gaz. She also reveals to Sonic, Tails, Knuckles, and Amy that the villain is causing the disruptions. Sonic and Amy thank Gaz for the information and that they know that someone is causing the disruptions and wonder who it could be. The villain reactivates the colossal Egg Robo the heroes fought at the beginning of Mix-Up. and taunts Membrane about terror unfolding. Membrane hopes in his mind that Gaz survives. Meanwhile, Sonic's group attacks, but is forced to take cover behind a hill and they plan a counterattack. The five heroes make several attempts to destroy the giant robot, but most are ineffective. Meanwhile, Calvin's group fights the alien illusions and Calvin rescues Susie from the T.Rex. However, the lead alien attacks the heroes with a squad of F-14s. Meanwhile, Talis is knocked into the ocean by the giant Egg Robo and Gaz volunteers to use her ship to fight the giant robot. Sonic agrees, remembering Zim's statement that Irken technology is more advanced than Human technology. Knuckles dives into the ocean and rescues Tails. Meanwhile, Calvin, Hobbes, and Susie fight the aliens and the lead alien reveals he has taken Moe hostage. Meanwhile, the robot attempts to kill Tails and Knuckles with its eye beams, but is distracted by Gaz flying her ship with Sonic. Sonic tells Gaz to get close to the robot for him to destroy it, which she does and she uses the ship's lasers to damage the robot's eyes while Sonic makes his way inside the robot's head. Meanwhile, Calvin is confused as whether to save Moe, but before he can come to a decision, the alien drops Moe in the water, and the battle recommences and Susie and Hobbes rescue Moe before he can drown. Meanwhile, Tails and Knuckles rejoin Amy and witness Gaz and Sonic causing significant damage to the robot. Tails and Knuckles join the dogfight in the Tornado and disable the robot's targeting mechanism. Sonic strikes the robot with his homing attack multiple times and eventually destroys the robot in a huge explosion. Sonic reunites with Tails, Knuckles, Amy, and Gaz, and they rejoice.  Membrane also praises his daughter's survival and the other four heroes for destroying the robot. Meanwhile, the villain orders the alien illusions to retreat. Despite the lead alien's protests to finish Calvin off, he reluctantly complies, but he vows revenge as he and the other illusions vanish. Calvin, Hobbes, Susie, and Moe set up camp near the shore. Meanwhile, Membrane vows that the villain will not succeed in his plans and that the heroes will come together and foil evil once again. The villain tells Membrane that Sonic is the only reason for Gaz's survival, but the villain warns the scientist that there are other ways he can make ends meet. Meanwhile, on Luna, an Irken scout reports to the Tallest about the battle Calvin's group fought against the illusions. The Tallest, remembering Calvin as the "Earth Leader" that negotiated with them to fight Eggman in Mix-Up, send a squad of Irken soldiers down to Earth to locate Calvin in hopes of enlisting his help in protecting them from Zim. Meanwhile, on Earth, investigator Bill visits a military base and is informed of the disruption crisis, where he begins his investigation on the identity of the villain and goes with two soldiers to investigate. Meanwhile, Gaz questions why the robot suddenly attacked. Sonic explains that robots cannot be programmed or reprogrammed to do something such as rebuild themselves unless ordered to do so by an outside force. Realizing that Eggman is no longer existing, Sonic immediately realizes the villain's identity and borrows Gaz's ship to find the culprit. Sonic flies the ship and eventually arrives at the villain's base. Sonic makes his way to the villain's central chamber where he confronts the villain himself. The mastermind of the dilemma is revealed to be Nega, an old rival of Sonic's. Sonic vows to stop Nega and attacks, but is restrained. Nega taunts Sonic about having second thoughts about stopping him and that although the heroes saved the world twice, they will fail to stop the obliteration of reality. Nega questions if the sacrifices of Shadow and Dib were worth saving the world for. Nega reveals that he desires to erase all of time and space so that the events of Mix-Up and Takeover never happened, which would result in Shadow reuniting with Sonic and Dib being resurrected. Sonic warns Nega that although rewriting reality would indeed prevent Shadow and Dib from sacrificing themselves, Nega's actions would also revive the villains the heroes have defeated in their previous adventures (Dr. Eggman, Metal Sonic, Tak, Mr. D., GAMP). Nega reassures Sonic that erasing and rewriting reality are the right things to do and the only way to resurrect Dib. Sonic replies that although Nega intends to undo Dib's sacrifice, he would risk deleting everyone in existence in the process, including himself, and vows to stop him. In response, Nega activates a small group of drones to attack Sonic. Sonic busts out of Nega's central chamber and makes it to the balcony, where he destroys several of the drones. Overwhelmed, Sonic climbs inside of Gaz's ship and escapes before the drones can close in for the kill. Sonic returns to his home island and isolates himself on the beach. Meanwhile, Bill questions two mercenaries who have connections to Nega. They reveal to Bill that Nega is responsible for the disruption and he used Mr. D, the sadistic criminal that pursued the heroes in Takeover, as part of his plans.The duo also reveal that Shadow had survived his sacrifice and that Swampy was on the ship at the time it was destroyed and that a teleporter was in his possession and that Shadow and Swampy are on Blorch. Bill realizes that if Nega figures out about Shadow's survival, he will try to kill Shadow to prevent Shadow from bringing him to justice. Bill and three soldiers run for the communication device in order to alert Shadow of the threat Nega will pose to him. Meanwhile, at Nega's headquarters, Nega is watching Bill's interrogation from a hacked security camera and becomes aware that Shadow is alive on Blorch. Knowing the threat Shadow could pose to his plans, Nega launches several capsules from his base containing unknown minions into space and orders the unknown minions to kill Shadow in order to prevent him from returning to Earth and the capsules blast off, heading for Blorch. Meanwhile, Calvin, Hobbes, and Susie are camping out.  Susie thanks Calvin for saving her life. Susie questions why Calvin saved her. Calvin says he did it to build a stronger relationship with others back home. Calvin also reveals that his adventures with the other heroes in Mix-Up and Takeover opened his eyes to his knack for mischief and he sought to improve upon it. Calvin explains the reason why he wanted to rejoin the other heroes was because he bonded with them the more time he spent with them. Susie reveals that she had to put up with Calvin's mood swings since he came back in Takeover and kept visiting him hoping they could spend time together, but she forgave Calvin every time. Calvin apologizes for all the things he has done to Susie before Mix-Up and explains he has done several things that he has regretted. Moe then arrives and tells Calvin of a spaceship coming to pick the group up. Calvin, Susie, and Hobbes are found by the Irken craft and they climb aboard. Calvin questions why the Tallest are on Luna, but the Irken sargeant tells Calvin that the Tallest will explain once they reach Luna, and the ship takes off, heading for Luna. Meanwhile, on Luna, the Tallest are contacted by Skoodge, who tells the Tallest that he is on Blorch with Shadow, whom the Tallest think is Sonic. Before he can explain more, Skoodge is attacked by an unseen figure, who he thinks is Shadow. The unseen enemy also disables Skoodge's communication device. Skoodge flees back to the crash site to alert Shadow with the minion in pursuit. Meanwhile, in the crash site, Omega receives Bill's distress call to Shadow, warning, Shadow that Nega is aware of his presence on Blorch before the beacon is destroyed by the enemy in pursuit of Skoodge. Shadow arrives and saves Skoodge from the enemy, which is revealed to be a Shadow Android. The Androids were the minions sent by Nega to stop Shadow from returning to Earth. Shadow and the e-series and Skoodge attempt to fight off the Androids. Meanwhile, Swampy breaks free and steals Skoodge's ship and escapes Blorch while Shadow and the e-series are fighting the Androids. Skoodge uses a mechanical arm from his PAK to latch on to his hijacked ship as Swampy takes off, heading for an unknown location. Meanwhile, Shadow and the e-series destroy the Androids and Beta informs Shadow that Swampy had escaped. The e-series continue their repairs while Shadow figures out what to do next. Meanwhile, on Earth, at Interpol headquarters, Bill realizes the connection was disabled and that he needs to figure out more about Nega's plans and he mobilizes several platoons of soldiers to help him search for Swampy. Meanwhile, Tails, Knuckles, Amy, and Gaz find Sonic on the beach and question him about the identity of the disruptor. Sonic reveals to the group that Nega is responsible. When Gaz questions where her father is, Sonic reveals that Membrane was not there when he was. Gaz is distraught and goes off in her ship to find Membrane on her own. Sonic looks on and lets her go to find Membrane and tells the others to respect her decision. Sonic and his group leave their island home to find the other heroes. Meanwhile, Nega is visited by the leader of the alien illusions pursuing Calvin. The alien questions why Nega ordered the illusions to retreat when they were in range of killing Calvin, and Nega tells the alien that plans changed when Sonic destroyed the giant robot and that now Calvin has escaped and is under the protection of the Irkens, they have to make him "feel safe" before initiating another attempt on his life. Nega assures the alien that the time will come when the alien can kill Calvin. The Lead Alien asks Nega to create a mechanical exo suit for him to fight Calvin more efficiently. Nega agrees to do so and the alien leaves. Nega then visits Professor Membrane, who is revealed to have been forced by Nega to create the Shadow Androids Nega sent to Blorch to kill Shadow. Nega expresses his disappointment in the Androids' failure to kill Shadow, but they succeeded in distracting the group long enough for Swampy to escape. Nega also informs Membrane that Gaz has left Sonic's group and is searching for him. Membrane vows that Nega will fail in his plan and Nega forces him to create the exo suit the alien asked Nega to create earlier and leaves Membrane to his forced labor. Meanwhile, Calvin, Hobbes, Susie, Moe, and the Irken scouts arrive at the Tallests' hideout on Luna, when Calvin has a flashback of his conversation with Nega earlier, and remembers hearing about the aliens following him until he reaches his 'true home". Calvin suspects that Luna is where Nega wants him to be, but becomes suspicious. Meanwhile, on Earth, Gaz is flying her ship over the rocky mountains in hopes of locating Nega's base in order to rescue Membrane. Meanwhile, on a hidden space station not too far from Earth, Swampy arrives in Skoodge's hijacked ship and enters the station, unaware that Skoodge latched on to the ship before he escaped Blorch. Skoodge then spies on Swampy as he makes his way through the station. Upon arriving at the bridge, Swampy is captured by Bill and four soldiers who then interrogate him on Nega. Swampy immediately confesses his ties to Nega, with Skoodge eavesdropping the interrogaton. Meanwhile, on Blorch, Shadow and Omega search for Skoodge and Swampy to no avail. Shadow and Omega are then contacted by Skoodge, who informs the duo that Swampy escaped by stealing his ship during their fight with the androids, but he snagged aboard at the last minute. Skoodge also reveals that Swamoy is now in the custody of Bill. Skoodge also reveals that when he eavesdropped on Bill interrogating Swampy, he overheard him confess that Nega is the mastermind behind the disruptions in reality. Shadow realizes that Nega is a descendent of Dr. Eggman from Mix-Up and returns to the crash site with Omega. Upon arrival, Omega confirms the source of the barrier, but reveals that the weapon is already disabled. Meanwhile, onboard the Massive, it is revealed that Zim disabled the weapon to enter the planet to find the Tallest and tells GIR to set a course for Earth. Meanwhile, on Blorch, Shadow and Omega reveal to the e-series of their discovery and Shadow tells them that although the ship is able to be repaired, it needs a power supply. Gamma detects Irken repulsors near the crash site (implied to be left behind by Skoodge and possibly other Irkens that set foot on Blorch). Realizing this, Shadow tells Omega and the e-series to finish reconstruction on the ship while Shadow heads for the location of the Irken repulsors guided by Omega. Meanwhile, on Luna, Calvin meets with the Tallest. Calvin questions why they are on the moon, to which the Tallest respond that Zim has figured out their deception and that he is trying to assassinate them. The Tallest reveal that they are aware that Calvin was friends with Zim and they want him to negotiate with him for a less violent approach. The Tallest also reveal that Shadow is on planet Blorch. The Tallest tell Calvin to make a decision as they believe the Massive is heading for Earth and if Calvin wants them off the moon, he will ease tensions with Zim before he instigates an unprovoked attack on Earth. Calvin and Hobbes race to make a decision. Meanwhile, Zim watches the screen in front of him as the Massive slowly heads for Earth. Later, Calvin sits alone in a chamber. He then starts questioning if his real home is with the Irkens, remembering his discussion with Nega. Calvin thinks back to when Nega stated that the alien horde would stop pursuing him once he reached his 'real home", and notices that the aliens have not attacked him since his arrival on Luna. Realizing this, but still very suspicious, Calvin contemplates staying with the Tallest. However, an Irken soldier alerts Calvin that the Massive has arrived: Zim has finally reached Earth. Calvin, knowing the danger Zim could pose to the humans during his violent crusade against the Tallest, dashes out of the room to alert his friends. Meanwhile, onboard the Massive, Zim commences his attack. He fires the Massive's beam cannon at the Tallests' base, but the beam is deflected by anti-beam weaponry. The beam accidentally hits the space station Bill is in. The blast knocks Skoodge off the station's rim, but he is saved by Irken fighters sent by the Tallest to engage the Massive. Bill and his men are unharmed, but the blast also destroys Swampy's containment cell, which gives Swampy the opportunity to escape in Skoodge's ship. As Swampy flies toward Earth, Bill and his men pursue him in a rocket. Meanwhile, on Luna, the Tallest observe the battle and drink martinis, unsure of what to do. Meanwhile, on Earth, Gaz flies her ship, trying to locate Nega's base, but gets caught up in Bill's pursuit of Swampy when Swampy opens fire on her ship. Gaz cleverly evades the shots and joins the chase. Meanwhile, Skoodge decides to aid the Irkens against Zim. Zim, aware that Skoodge was his companion on Irk, hesitates for a moment until Skoodge opens fire on the Massive. Zim retaliates by using the beam cannon to destroy half of the Irken fleet. Meanwhile, Bill and Gaz pursue Swampy through the sky. Swampy evades most of their shots, but Gaz finally lands a hit on the ship's thrusters. Bill and Gaz land safely while Swampy is trapped in the falling ship. Swampy unsuccessfully attempts to regain control of the ship, but Nega teleports him away as the ship crashes in a valley. Meanwhile, in space, Zim activates the SIR robots onboard the Massive and unleashes them and GIR on the Irken fighters and Skoodge. GIR and the SIR robots easily take down the remainder of the fleet and Skoodge retreats. Meanwhile, on Luna, Calvin meets up with Susie, Hobbes, and Moe outside the Tallests' base. The Tallest inform Calvin of Zim's unprovoked attack on Luna and soon Earth just as the anti laser weaponry is destroyed by GIR. Calvin is wounded by GIR's gunshots and Hobbes realizes GIR is being controlled by Zim. Meanwhile, GIR returns to the Massive, but is confronted by Skoodge. GIR easily overpowers Skoodge and he retreats. GIR tells Zim, who has become megalomaniacal after the events of Takeover, that their attack is complete and Zim and his army proceed to attack Earth. The SIR units arrive on Luna and begin a massacre by killing most of the Irken soldiers. The Tallest, realizing that all hope is lost, scream as they are seemingly gunned down by the SIR units. Meanwhile, on Earth, Bill and Gaz meet up with Sonic, Tails, Knuckles, and Amy and Bill informs them of Zim's attack on the moon that will proceed to Earth if nothing is done. Sonic explains to the heroes of he and Zim's mission on Xevious how Zim found out about the Tallest using him as a pawn from Tak in Takeover. Bill also tells the group that Zim disabled the force field activated from he Nazca Lines in Takeover. Sonic and his friends decide to go after Zim before he devastates Earth while Bill decides to head for the Nazca Lines to reactivate the weapon. Sonic and Bill agree on the plan and Sonic, Tails, Knuckles, and Amy head for Luna on the Tornado while Bill, his men, and Gaz take the rocket to Peru to reactivate the force field while also attempting to locate Membrane and Swampy. Meanwhile, the Massive slowly begins to approach Earth with the fleet unable to stop it. Meanwhile, on Luna, Calvin, Susie, Moe, and Hobbes meet up where the Tallest are dying, discussing what to do. Susie suggests they evacuate Luna and alert Earth's leaders of the threat as Zim is completely insane and innocent people are about to pay for it. Just then, Sonic, Tails, Knuckles, and Amy arrive in the Tornado and Calvin and his pals greet them. Sonic vows that he will stop the psychotic Zim from ravaging Earth and save everyone. Sonic and Tails tell Calvin and his friends to shelter themselves in the hideout while Sonic himself stops the Massive. Hobbes warns Sonic to look out for GIR as he was present in the battle, and Sonic and his group board the Tornado and join the dogfight while Calvin and his group stay behind to contact the military to prepare to defend Earth against the Massive. Meanwhile, in space, the Tornado flies with the fleet on the offense against the Massive. Meanwhile, onboard the Massive, GIR informs him that Sonic is attacking the Massive. Upon realizing this, Zim is furious and fires the beam cannon and hit the Tornado, causing it to spin out of control. Meanwhile, on Luna, Hobbes suggests Calvin and his group evacuate, but a concerned Calvin insists on going to Sonic's aid, but decides to go along with Hobbes anyway. Meanwhile, in Nega's headquarters, Nega and Swampy are observing the attack on Luna through a hacked probe drone. Nega insists that Zim is interfering with his plans to keep Calvin from believing he is in danger and says something must be done. Nega orders Swampy to activate a powerful weapon called the "Infernal Machine" to destroy the Massive. Nega silently states that the Infernal Machine has been successful many times and it better not fail, unaware that he is being eavesdropped by Professor Membrane, who sneaks away. Meanwhile, in space, the Tornado is ambushed by SIR units, but Sonic and Knuckles destroy them and rescue Skoodge. Tails maneuvers the Tornado around and uses the Tornado's guns to disable the Massive's laser cannon. Zim retaliates by activating an electric shielding laser system which electrifies the fleet and destroys more fighters, though Tails is able to navigate it. Amy is abducted by SIR units, but fights them off. Tails is also ambushed by SIR units, but is rescued by Sonic and Skoodge, ho destroy them. The heroes then reunite with Knuckles and Amy. Onboard the Massive, GIR reports to Zim about Sonic's counterattack, but Zim tells GIR to remain in the bridge and observe for the Tallest. GIR informs Zim the Tallest have disappeared and is not aware if they are alive. This infuriates Zim and he reactivates the laser cannon and destroys the remainder of the fleet and speeds up the progress to Earth, intent on destroying all Irken prescence on Earth. Sonic, Tails, Knuckles, Amy, and Skoodge pursue the Massive. Meanwhile, Calvin, Susie, Hobbes, and Moe barricade themselves in the Tallests' hideout, seeking a way to escape. Meanwhile, on Earth at the Nazca Lines, Bill and Gaz discover the deactivated superweapon and Bill deduces that the weapon cannot be reactivated. Gaz is contacted by Membrane who warns her of Nega's plans to obliterate reality and of the Infernal Machine. Membrane tells Gaz to be safe, but Gaz refuses to leave her father with Nega. Mermbrane explains that he never gave Dib or Gaz much attention due to his scientific work for the world government and apologizes for his absence. Membrane encourages Gaz to be brave to see Nega's plans through and that there "will come a time when they can be a family again". Meanwhile, in space, the Tornado is in pursuit of the Massive. Knuckles says the Massive cannot be stopped. Meanwhile, on Luna, the dying Tallest attempt to recover when they are spotted on Zim's sensors. Zim,  with victory in his grasp, fires his laser cannon which leaves Luna completely intact, but destroys the Tallests' hideout. Calvin, Hobbes, Susie, and Moe survive the blast, but the Tallest are killed. Zim then advances towards Earth, reprogrammed to destroy the humans as he was originally ordered by the Tallest to achieve. Sonic and his friends land the Tornado and reunite with Calvin and his friends and watch as the Massive advances on Earth. However, a wormhole opens and sucks the Massive in. Zim, intent on extracting his vengeance on his enemies, uses a tractor beam to abduct Susie. Calvin screams in frustration as the Massive is engulfed by the wormhole. Meanwhile, on Earth, Bill and Gaz arrive at the Nazca Lines and come across technology ejected from Tak's ship in Takeover. Gaz wanders through the technological junkyard and comes across the body of Dib, much to her surprise. Meanwhile, on Luna, Calvin reports the deaths of the Tallest and the abduction of Susie at the hands of Zim. Sonic, Tails, and Knuckles question Calvin about his experiences, and Hobbes reveals Calvin's alleged conversation with Nega who put Calvin in doubt about his life being a fantasy. Hobbes also explains to the heroes that Calvin has been pursued by aliens from Calvin's imagination somehow made real. Before Calvin can explain further, the heroes notice two small figures fall to the ground in front of them, revealed to be Skoodge and a deactivated GIR. Meanwhile, at the Nazca Lines, Bill comes across Gaz carrying Dib's body, who suggests taking her brother's body with them to the Infernal Machine. Bill and Gaz then take their leave in Bill"s rocket, taking Dib's body with them. Meanwhile, on Blorch, Shadow roams across the barren surface of Blorch while being pursued by Shadow Androids. Upon destroying more androids, Shadow finally comes across the Irken repulsors. Shadow returns to the crash site with the repulsors to find that Omega and the other robots attempting to repel an attack by androids. After Shadow helps the robots destroy the androids, Omega uses the repulsors to increase the repair process. Shadow also recovers the head of one of the androids and notices a form of encrypted code. Omega deciphers the code and reveals the location of Nega's base to Shadow. The black hedgehog begins to speculate that someone is working against Nega from the inside. Meanwhile, on Luna, the heroes discuss how to dismantle Nega's master plan and Sonic reveals the offer that Nega made him during their confrontation. Sonic suggests the heroes somehow reverse time to the point before the heroes met so that the events of the series never happened in order to undo the casualties they suffered during their adventures. Calvin, upon realizing that he will return to his boring life before he met the heroes in the process, becomes infuriated with Sonic, and chastises him about reversing all the good times he had with the heroes in their previous adventures. Sonic tells Calvin that he feels regret over Dib's death and Shadow's disappearance into the unknown. Hobbes is about to reveal to Sonic that Shadow is still alive when GIR suddenly awakens and attacks. Meanwhile, Gaz and Bill finally discover the Infernal Machine in the middle of a dark chasm. Upon landing, Bill and Gaz begin to investigate the Machine to find a way to disable it, but are confronted by Swampy and a squad of Shadow Androids. Meanwhile, on Luna, Sonic and the other heroes fight GIR while Bill and Gaz fight Swampy and the Shadow Androids. Gaz confronts Swampy about her father's whereabouts and engages in a furious battle with the reptilian. Bill is able to destroy the androids and an android's head falls where Gaz is standing, briefly distracting her. Noticing that Gaz is distracted, Swampy attempts to flee, but is struck by Gaz, causing the greedy reptilian to fall into the dark chasm below. Gaz regroups with Bill and shows him the android head and discovers the same code that Shadow found on Blorch regarding Nega's location and begins to decipher it. Meanwhile, on the moon, the heroes manage to subdue GIR and Amy reasons with GIR, causing the robot to revert back into his cheerful mode. Meanwhile, at Nega's base, Nega is confronted by Membrane, who reveals that he had embedded the coded coordinates to Nega's base into the Shadow androids. Membrane then comments that Nega was distracted by his intricate plan that he overlooked his use of Membrane's scientific genius to carry his plans forward. Nega attempts to establish contact at the Infernal Machine to no avail due to Bill and Gaz's actions, distracting him long enough for Membrane to flee. An infuriated Nega talks to the commander of the alien illusions and informs him of Membrane's deception and his escape as well as losing contact with the Infernal Machine. In response, Nega and the alien commander retreat into a hidden bunker beneath the base. As Nega departs, Membrane emerges from his hiding spot, and sprints back inside the base before the building goes on lockdown. The scientist makes his way to Nega's control chamber and discovers that Bill and Gaz have infiltrated the Infernal Machine. Back on the moon Sonic and his group are contacted by Bill and Gaz through GIR and inform Sonic of their infiltration of the Infernal Machine. Sonic then informs Bill that Susie has been abducted by Zim. Since the wormhole was created by the Infernal Machine, Bill decides to use the device to reopen the wormhole. Sonic considers the risk of Zim pursuing the heroes out of the wormhole upon rescuing Susie and tells Tails and Amy to return to Earth to alert the world's leaders of the chaos and to find more allies to help the heroes in their cause. Bill tells Sonic that Gaz has been able to locate Nega's base with help from Membrane, but Nega himself has recently relocated to an unknown location. Bill uses the Machine to reopen the wormhole and tells Sonic to enter the wormhole while he and Gaz continue to search for Nega. Sonic, Knuckles, Calvin, Moe, Hobbes, GIR, and Skoodge enter the wormhole as Bill bids them luck. After Sonic and his group emerge on the other side of the wormhole, they find themselves in a strange place with a black sky and barren environment. Skoodge tells the heroes that they are in a pocket dimension, a small area outside of time and space. Suddenly, Calvin has a vision of Zim torturing Susie for stealing the Tallest from him and demands information on where they are. Calvin alerts Sonic and the heroes sprint into the horizon. Meanwhile, Nega and the alien commander arrive at the villain's secret hideout. The alien contemplates what they must do now that the Infernal Machine is lost, to which Nega replies that it is a minor setback and tells the alien that he must check on mysterious prisoners. Unbeknownst to Nega, Gaz and Bill are listening in on the conversation via a transmitter and discover Nega is holding prisoners. With this information, Bill and Gaz continue to Nega's location to find Nega and discover his prisoners. Meanwhile, the alien commander instructs his second-in-command to lead the other aliens to into the reopened wormhole to capture Calvin so that the alien commander can execute him and remarks that he has a "surprise" for his adversary. Back in the pocket dimension, the heroes are attempting to locate the Massive via Skoodge's scanner to no avail. Calvin apologizes to Sonic for his earlier outburst, but states that he is still confused as to what Nega was trying to tell him. Calvin also expresses doubt that the heroes will be able to save the world from Nega. Sonic reassures Calvin that they will rescue Susie and stop Nega. GIR alerts the heroes that he has located Zim, and the heroes proceed to engage in battle with the insane Irken. However, the alien illusions arrive shortly afterward to capture Calvin, leading to the heroes to begin combating the aliens. Zim takes advantage of the opportunity and flees into the barren landscape, but his jetpack is damaged and leaves a trail behind. Meanwhile, Tails and Amy arrive on Earth and are led to a mysterious base, where they find a frozen creature. Meanwhile, Sonic and his group hold off the alien attackers and subdue them, forcing the aliens to retreat. with the aliens dealt with for the time being, Sonic and Calvin and the other heroes resume their pursuit of Zim. Meanwhile, on earth, Bill and Gaz land near Nega's hideout. As the two approach the hideout, one of Nega's mech soldiers notices them from a safe distance and alerts Nega, who then mobilizes his mech soldiers to eliminate Bill and Gaz. Upon arriving at Nega's hideout, the duo are attacked by Nega's mech soldiers. Nega contemplates that another precaution is necessary and activates an unknown function. Meanwhile, Tails and Amy notice that the frozen brute is thawing out due to Nega's tampering. The monster is revealed to be a giant mutated turtle like monster and attacks the duo. Meanwhile, Susie manages to escape the Massive via a portal to link up with Tails and Amy, who are joined by Galaxoid and Nebular. The group fights long and hard against the monster and finally defeat it. Meanwhile, Gaz and Bill struggle to fight against Nega's egg pawn soldiers and manage to proceed further into Nega's fortress. Before Bill and Gaz can confront Nega, they are subdued by the alien visions. The duo are presented to Nega. Bill and Gaz demand to know Nega's reasons for wanting to destroy reality, but are interrupted by an argument Nega has with the alien leader, who questions Nega'a plans and announces his intentions to use the battle suit designed for him by Membrane, despite Nega's warnings, reminding how Membrane's Shadow Androids failed to kill Shadow. Nega relents and lets the Alien leader take his leave to hunt down Calvin. Nega reveals how he had planned to use his pocket dimension to entrap the heroes to prevent them from interfering with his plans and taunts the duo of the heroes' doomed struggle. Meanwhile, Sonic, Knuckles, Calvin, Moe, and Skoodge are following the trail left behind by Zim's PAK, and Skoodge explains how the PAK acts as a life support for an Irken.

Fueled with feelings of revenge, Zim teams up with GIR to track down the Tallest and assassinate them for their crimes, thus, ending the Irken Empire's threat to the galaxy. After Zim successfully assassinates the Tallest, Zim becomes consumed by his insanity and becomes a potential major antagonist.
GIR - Zim's crazy robot sidekick and a deuteragonist of the show. GIR was left behind on Earth after Zim left Xevious find the Tallest. GIR later rejoins his master in searching for the Tallest and assassinate them, which will also bring the Irken Empire's age of conquest to an end.
Dib - Intelligent kid who was Zim's rival on Earth, but befriended him. Dib sacrificed himself to rescue Zim from Tak near the end of Takeover. His death has taken a heavy toll on Sonic, Zim, Calvin, and his sister Gaz as well as his father, Membrane. Dib appears in many flashbacks throughout the show, which frequently hints of his possible return/ressurction.
Gaz - Dib's younger sister who becomes a major female protagonist of the show. Like Zim and Calvin, Gaz is greatly angered by her brother's sacrifice and uncovers a scheme to send reality into oblivion masterminded by Nega. Her father Membrane, concerned for losing her like he lost Dib, attempts to prevent her from helping the heroes' efforts to regroup and stop Nega, but goes against her father's wishes regardless and finds Sonic and his friends. Gaz teams up with Sonic and his friends to reunite the other heroes and to prevent Nega from destroying reality.
Professor Membrane - A successful scientist and father of the late Dib and his sister Gaz. Membrane is coping with the sacrifice of his son throughout the show. Membrane eventually uncovers the plans of Nega to destroy reality and tries to persuade his daughter Gaz away from the dilemma while he struggles to find a way for the heroes to stop Nega, though Gaz takes action regardless. Membrane helps the heroes from behind the scenes on many occasions.
Bill - A highly skilled government agent who helped the heroes defeat the Xevians a few months earlier and captured Dr. Eggman at the end of Mix-Up. In the show, Bill investigates the motives and whereabouts of Nega who seeks to destroy all of reality.
Skoodge - Irken agent who was a childhood companion of Zim. Zim and Skoodge grew up together on the Irken homeworld, Irk. Together, Zim and Skoodge attempted to escape an underground military base. Skoodge was injured, but Zim rescued him and the two escaped. After Zim was sent to Earth, Skoodge was sent to planet Blorch by the Tallest to conquer it, but he, like Zim, defected. During the show, Skoodge comes across Shadow and Omega, and teams up with the duo to find a way off Blorch and to find a way to return to Earth to stop Nega and his plan to destroy reality.
Moe - Bully at Calvin's school who serves as a foil to Calvin and is a minor villain of the show. During the show, Moe is captured by aliens from Calvin's mind and gives them information on Calvin's location. Moe is later released and follows Calvin on the run.
Illusions - Group of aliens and other alien-like creatures from Calvin's mind who are supporting antagonists in the show. They were mere figments of Calvin's imagination, until Nega uses his powers to make the Aliens reality. Their goal is to stop Calvin from regrouping with the other heroes in order to stop Nega from destroying reality. They also capture Moe to figure out Calvin's location. The Alien Illusions spend most of the show pursuing Calvin and his friends in order to eliminate them. 
Almighty Tallest - Zim's former superiors and supreme leaders of the Irken Empire who are obsessed with snacks and galactic conquest. The Tallest are the masterminds behind the Irken Empire's goals of conquering the galaxy. At some point, the Tallest selected Zim to participate in Operation Impending Doom I, but Zim foiled the plan by nearly destroying an Irken base on Irk, the Irken homeworld. After this, the Tallest began to view Zim as a threat to their plans to conquer the galaxy, so when it came time to instigate Operation Impending Doom II, the Tallest gave Zim a fake mission to conquer Earth (although the Tallest did not know there was such a planet) to prevent him from foiling Operation Impending Doom II. In the show, the Tallest are forced into hiding after Zim attacks and takes the Irken flagship, Massive. The Tallest eventually reach out to Calvin for help in stopping Zim.
Nega - The mastermind behind the anihalation of reality and the primary antagonist of the show. He appears to have been an old foe of Sonic. Nega is arguably the most dangerous villain in the Dimension saga. Unlike Eggman or Tak and most of the other villains in the saga, Nega prefers to watch his enemies' progress from behind the scenes. It is revealed by Shadow that Nega was organizing his master plan during the events of Mix-Up and would plan to put it into effect five years later. After five years and months of planning, Nega puts his plan into effect and orchestrates the events of the show. Like most other villains from other forms of literature, Nega is intelligent and manipulative, which is proven when Nega tricks Calvin into believing his hometown is not his true home and he must return to his real "home" to set things right. However, Membrane implies that Nega is somewhat insane, willing to risk anything to destroy reality, even if it would cost his own life. Throughout the show, Nega's main goal is to destroy and erase all of reality. After the destruction of reality, Nega plans to recreate reality in his own image, where evil runs freely. However, the heroes prove to be a constant threat to Nega's plans.
Swampy - A reptilian and Nega's henchman and the secondary antagonist. Swampy is of unknown origin, but has done Nega's bidding for many years while hiding from human society while being unknowingly followed by Shadow. Unlike other villains in the saga, Swampy never speaks. Throughout the story, Swampy serves as one of the many obstacles in the heroes' path to defeating Nega and is shown to attack any enemy that stands between Nega and his ambitions. Like several villains in stories, Swampy is greedy and selfish (evidencd by his menacing snicker when he appears), but is also a coward as he always attempts to flee during a battle rather than stay and fight
