Sonic X Episodes

Sonic returns to his planet after releasing the seven chaos emeralds into space. Sonic's friends are watching the skies for a meteor shower but get a surprise when an Alien named Cosmo crashes her spaceship right before their eyes! As she is recovering, a Metarex lands on Earth, destroying everything in its path in search for the Planet Egg. Sonic, Knuckles, and Tails battle the Metarex, but can't stop him from escaping into space. As Cosmo introduces herself to Sonic, an old friend makes a suprise appearance.

Chris has made it to Sonic's world, but the strange time lapse has turned him into a kid again. As Sonic recovers from his battle, Cosmo reveals the mission of the Metarex: to steal every world's Planet Egg, the heart of each planet that sustains life. Using Tail's Blue Typhoon Ship, powered by the Master Emerald, Sonic and friends prepare to foil this evil plan. But when a new Metarex comes to interfere with their goal, it's up to Sonic and Knuckles to keep it at bay. As the Blue Typhoon launches into space, Sonic destroys the Metarex in a giant blast! Sonic and his friends are on their way, but the quest to save the Universe has only just begun.

As Sonic and the others find one of the Chaos Emeralds, Chris's friends and family discover that he's gone. Using submarines, the gang travels deep into a waterlogged planet only to land on an island inhabited by Metarex. When Sonic is captured by these metal meddlers, Amy devises a plan to save Sonic, but she'll have to hurry before Sonic becomes shark bait!

Planet Secco's Planet Egg has been returned, and as life for its inhabitants returns to normal Sonic and friends are honored for their heroism. Meanwhile, Knuckles has found one of the Chaos Emeralds, and Eggman is determined to take it. He tricks Knuckles into believing he has changed his ways. Sonic and the others see through Eggman's trick, though. While Sonic and Knuckles fight it out, Eggman and Rouge both scheme to steal the Emerald. But a new Metarex gets in their way. It's a four-way free for all, with a Chaos Emerald as the prize!

Having found the first of the seven Chaos Emeralds, Sonic and friends are back on the hunt, detecting a second emerald on Planet Breezy. But Eggman is still hot on their trail. As our heroes face yet another Metarex in a battle to save the planet, Rouge has a plan of her own to steal the precious jewel.

When Sonic and the gang encounter two Metarex making a getaway with a Planet Egg, they use the Power Cannon to thwart their plans. Unfortunately, Sonic is launched too far, and is hurled onto a nearby planet. When he recovers from his fall he finds an unconcious Eggman nearby, with a chaos emerald laying by his feet! As the gang searches for Sonic and the planet egg, Amy, Cream, Cheese, and Cosmo are captured by a small Metarex, but not for long! They escape, but when Eggmen steals back the Chaos Emerald, it's Chris and Sonic to the rescue.

Chris's parents use their son's transporter to send his belongings to Sonic's world. Cream's mother asks Vector and his gang to track down Chris and deliver his stuff. Vector is happy to oblige, but when they reach the Blue Typhoon, instead of being welcomed, they are attacked! Tails and the others have mistaken them for Metarex. Once they realize their error, the crew of the Blue Typhoon invite Vector and his cohorts onboard. It's not long, though, before Vector gets over-zealous and decides to take Cream back to her mother, without even asking her! But Cosmo and the others aren't about to let that happen.

Rouge is about to swipe one of Eggman's emeralds when she comes across a secret stowaway: Shadow! The crew of the Blue Typhoon go emerald hunting on a deserted planet where things get spooky: Sonic, Amy and Knuckles explore a creepy castle, while Chris and Cosmo discover a foreboding warning left behind by the planet's vanquished former inhabitants. When the entire castle turns into quicksand and swallows up Sonic, a fierce battle ensues, pitting our heroes against a new kind of powerful Metarex. Just when all appears lost Sonic and company get a blast from the past... as Shadow the Hedgehog suddenly comes to their rescue. Before they can thank him however, he snatches up their Chaos Emerald and vanishes!

Scar Ship, a fearsome Metarex battleship capable of demolishing entire fleets of resistance fighters, is called upon by Dark Oak. Its new mission: destroy Sonic the Hedgehog and Dr. Eggman. Scar Ship begins by launching a suprise attack on Eggman's ship. Despite Shadow's best efforts, it appears all hope is lost for Eggman and his crew. Rouge manages to escape, and soon informs Sonic and the gang of what has happened. Cosmo recognizes the ship: it is the same one that destroyed her family and friends! The gang decides to take on the ship in a battle royale! But it will take some cunning trickery, and some unexpected help, to take it down!

Sonic and the gang go exploring another deserted 'ex-planet,' looking for emeralds. When Cosmo and Tails enter a canyon cave, Cosmo accidentally presses a hidden button that causes them to plunge into a huge underground cavern. The two spot some weird fireflies which they follow to a huge Metarex fortress! Once inside they discover a chaos emerald factory which uses a real emerald to create fake ones. But when they're spotted by the Metarex, they grab the emerald and run! Just when they think they're safe, the Metarex catch up with them and all seems lost. Luckily, at the same moment Sonic and the rest of the gang show up and help them defeat the Metarex and make their escape.

Both Eggman and Sonic's gang have located the last two chaos emeralds. Unfotunately, they are onboard a heavily guarded Metarex space fortress. Eggman proposes a little teamwork: Members from each group will enter the fortress and disarm the security system. After that, it's a race for the prize, finders keepers! Sonic and the gang agree, and Chris joins Shadow and Rouge on a mission to disarm the alarm. They're successful and both teams set off for the emeralds. Sonic's gang easily takes the lead, but Eggman has some dirty tricks up his sleeve. When they finally reach the emeralds, they find the Metarex are using them for their evil plans. Before they know it, our heroes come face to face with Dark Oak himself, the ruler of all the Metarex!

Sonic squares off with Dark Oak and his army of Metarex. Meanwhile Tails reports that the Blue Typhoon has been surrounded by Metarex battleships. Cosmo uses the code she deciphered to swipe the Metarex's emeralds and release the Planet Egg. When the Metarex realize what has happened they open fire on their own fortress, hoping to destroy Sonic and the others along with it. Chris is able to nab Eggman's emeralds, so all seven are now together again. Sonic and Shadow proceed to have a Super Showdown.

Chris spots an unidentified spacecraft and sounds the alarm, but it's only Vector and his gang. They've been lost in space since delivering Chris's things and now they need Tails' help to repair their ship. Vector agrees not to cause any trouble, but old habits die hard: He comes up with a scheme to play match maker for Cosmo and Tails. As Cosmo plans a surprise party for Sonic and the others, Vector tries to force a love connection. In the end, though, Tails makes his own move.

The brave crew of the Blue Typhoon steer the ship directly into a gravity pool in order to reach an intergalactic cloister. Once inside the ship immediately gets caught up in vines, giving Yellow Zelkova a chance to find them and attack. As the fight ensues, Sonic realizes that they will never match this Metarex's brawn, but but they can beat it using their speed. Eventually they are able to use the Sonic Power Cannon to put Zelkova out of commission. As the Blue Typhoon speeds off Chris worries about what might lay ahead.

Sonic and the gang realize the Metarex are leading them somewhere, but decide to go along anyway. Soon they find themselves at Black Narcissus's base, located on a planet recently destroyed by the evil Metarex. The base is a fake emerald factory. Black Narcissus lures Cosmo and Chris into his base by promising information about Cosmo's ancestors and the Metarex. But it's just another dirty trick, and as soon as they arrive Black Narcissus takes them prisoner. Now it's up to Sonic to save the day. But in order to rescue his friends he must first battle two robots created by Black Narcissus to test his abilities. He gets some unexpected help when Eggman and company intervene on his behalf. But do Eggman's good deeds really mean he's changed his ways?

Eggman and his crew encounter a space battle between the Metarex and a band of rebel fighters. Shadow fights alongside the rebels and they are able to force the Metarex to retreat. Thankful for the help, the rebels agree to give Eggman their Chaos Emerald. But all is not as it seems. Leon sends Molly, along with Shadow and Rouge, to retrieve the Emerald, but it's a trap. Leon and his fellow soldiers have decided to make a deal with the Metarex, but they know Molly will never go along with it. So they have set up a bomb to destroy her! Meanwhile, they plan to hand over Eggman to the Metarex, so that they might be spared. But Shadow saves Molly and Rouge from the bomb, and Eggman catches wind of Leon's plot to betray him.

The ship's scanner has located an Emerald inside what seems to be a stray asteroid. But this 'asteroid' turns out to be a spaceship, piloted by strange creatures from a dying planet called Marmolin. Unfortunately, despite pleas from our heroes, these space travelers refuse to part with their emerald. Sonic and his friends are able to win them over, however, by giving them a ride home and investigating what is making the planet sick. But Marmolin is no ordinary planet. It's filled with magic, spells and fortunes. Amy is eager to try out a powerful love spell on Sonic. Chris traces the planet's problems to an underground disease located where the Planet Egg was. By blasting Sonic into the ground they are able to destroy the disease, and heal the planet. Afterwards, Tails and Cosmo accidentally set off a love trap that was set by Amy for Sonic. Amy cannot contain her frustration as a new love between Tails and Cosmo blooms.

Eggman sits in the throne of the Four Metarex heavenly King's seat after the death of Red Pine. As for the Chaotix Detective Agency. Their ship is still wandering through space.

Blue Typhoon is pursued by Metarex and is surprise attacked by Yellow Zelkova and makes a crash landing on Planet Thunder Bolt.

There is an intruder on Blue Typhoon. It turns out to be Shadow who is after Cosmo's life.

Blue Typhoon had warped to Planet Green Gate thanks to Cosmo's power. The place that Blue Typhoon makes a crash landing is the remnant of a broken, burnt tree with a cloudless blue sky that spreads over to the horizon. Sonic dashes off to check the planet out. Amy and Rouge go after him. They find out that a tracking device that is linked to Cosmo's visual and auditory senses is embedded in her brain. If they remove this device Cosmo will lose her visionary and auditory senses. Chris and the others are enraged. Cosmo, who is awake at that time, overhears their conversation.

Despite the last battle right before them, Sonic and the others look quite cheerful. Double-Triple O finally comes into view. Right ahead of them is Planet Acryleus with the Chaos Emerald and a gigantic Planet Egg. The Metarex fleet counter-attack them. The first to fight them are the heavenly kings, Black Narcissus and Pale Bay Leaf. Sonic and the others sally forth on each of their fighter crafts. In the midst of the battle, Shadow and Team Chaotix suddenly come warping out, and charge into the mother ship. The violent battle transforms into a confound conflict, and yet into a rough-and-tumble fight.

Chris and the others place their hopes on the Master Emerald to cause a miracle. They will try and slam the energy of the Master Emerald onto the Chaos Emerald by using the mechanism of Sonic Driver. With the help with Shadow as well as Chaotixs, they try with all their might to push back the attacks of Final Mover, as they work on what they have to do. In the midst of all this, Eggman tells Chris of a shocking fact. He tells Chris that if they lose the Master Emerald, Chris may never be able to return to his world ever again. However, Chris says he would have no regrets even if that were to happen and continues working. Then, he fires Sonic Driver along with the power of Master Emerald. That instant, the Master Emerald shatters to pieces. But Sonic Driver strikes Final Mover and opens a large hole in it.

Final Mover turns into a gigantic fruit. The energy of the fruit increases even more. Wanting to stop forestation, Sonic and Shadow launch an attack, but in vain. Forestation progresses even as the battle continues. The fruit begins to suck up the energy of Sonic and the others. The only one capable of moving now is Cosmo, since she belongs to the same kind as Metarex. Cosmo takes the Chaos Emerald that have had all its energy sucked out and runs. The things she has encountered throughout her journey and her memories will not let her give up.

Now that the final battle is over, what happens next?
