Sonic Medley: Have A Chaotic Time To Travel

Sonic Medley: Have A Chaotic Time To Travel is series special that takes place after the events of Sonic X season 3, but also featuring characters from Sonic the Hedgehog (TV series), Sonic Underground, Sonic Boom (TV series), the Archie and IDW comics, and Mario & Sonic at the Olympic Games.

Synopsis
The timeline has been altered. A new face arrives on Earth destroying everything to do with Dr. Eggman and his grandfather, Gerald Robotnik. But when the newcomer comes Mobius, Sonic, friends and Shadow are in for the shock of their lives to discover that this new face is someone the Ultimate Lifeform hasn't seen in over 50 years. Who is this mysterious Freedom Fighter, and why does she seem so familiar?

Part 1
In a lab, which is located on the Space Colony ARK, a mysterious scientist with name "Kintobor" walks to the shelf that has canisters with blue, white, and black quills and throws them in a beaker to extract the essence of Chaos energy, turning the liquid yellow and then poured into a test tube ready to be sent into a time window that showed where the scientists are studying in their field before the raid happened. One of them noticed a package that contained the test tube and note that says to give it Maria Robotnik that will cure her of her illness. After that was accomplished, the raid began exactly as expected and Gerald was apprehended with Maria and Shadow running from the GUN soldiers to the room with the escape capsules. Shadow was in one of the capsules while Maria had to stay behind to ensure that the Ultimate Lifeform escaped, but not before pleading to help people and give them a chance to be his friend. But unbeknownst to Shadow, Maria not only looks stronger, but she feels stronger, too. As Shadow's capsule was launched, a bright light had appeared inside. Was it an explosion, or could it be that someone used Chaos Control? How is it possible?

Fast Forward

On the planet Cascade, the Metarex arrive to kidnap Eggman per one of the comrades, Leon's orders until the plan fell apart and Molly learns of her team's betrayal with her own eyes. When Shadow came and promised her that he will always be there when she needs him, she's suddenly became inspired by his words just like the story of Black Wind. With one final look at Shadow, Molly flies towards the Metarex fleet, and just as the black hedgehog goes to join her, a bright blue light streams in the sky and flies in Molly's view between her and the Metarex ships. In a blink of an eye, Molly disappears from her ship, as do the other Cascade comrades from theirs. And then, a bright flash engulfs the sky and the Metarex ships in it. There doesn't seem to be any survivors other than Eggman's space craft, and Rouge and Shadow are pondering what just happened. Then, out of nowhere, a note appears from the Chaos Emerald they found when they were looking for Metarex files, which turned out to be a trap set by Leon and his teammates.

''I have saved your friend from a horrible fate that was just waiting to happen. And don't worry about the others; they're safe, too. Leon and his teammates are teleported to the Chaotix Detective Agency where they will be safe, but not without punishment for their betrayal to their own. And Molly is on another planet, but I do not know how she will return. I hope to see you again one day, Shadow. Promise.

M.R.''

Those two initials struck like a chord for Shadow. He knows this, and that bright light he saw was the same as when he escaped in the capsule while Maria had to stay behind. Could it be...?

Fast Forward

Sonic and his friends have reached the coordinates sent by Dr. Eggman to save said evil genius from the clutches of the Metarex and attempted to prevent a phenomenon that occurs once every thousand years. As the planet reaches its Final Mova stage, Dark Oak attempts to crush the planet egg when Cosmo transforms and goes to immobilize him so that Super Sonic and Super Shadow can destroy the Metarex and save the galaxy. The Sonic Power Cannon is fired, and to everyone's surprise, the same blue light from Cascade joins the two hedgehogs towards the tree, and it seemed that Dark Oak is no more...and neither is Cosmo it seems. Tails is crying for the loss of his friend...until a hand touches him and he looks to see...an alive Cosmo! The fox cried with joy to see her alright, afraid that he had killed her, but Cosmo assured him that he didn't revealing to him that she was saved by someone. But who? It wasn't Shadow or Sonic, but something did join the two hedgehogs towards the tree and unexpectedly pulled Cosmo out before the blast hit. And just like what happened with Shadow and Rouge, a note appears but from one of Cosmo's rose petals, signed with same initials: "M.R". Why does it sound so familiar?

10 years later

The story opens up to an open desert on Earth in the daytime when something flies over the scorching sand with two riders flying by hoverboards with two passengers behind them. One other passenger up front is standing on the engine's wing belonging to someone piloting it, who turns to the one waving a glove hand, gesturing that it's the target they're looking for; Area 99.

Somewhere far in the desert, a photo shoot seems to be taking place as Lindsey Thorndyke, the film star and parent of Christopher Thorndyke, is posing in front of the camera when Sam Speed, her brother and the uncle of Chris, heard what sounds like a jet fly by and in the corner of his eye, there is indeed a fighter jet soaring in the sky, but none like he's seen before except for the X Tornado since Sonic and his friends arrived on Earth. Nelson, the husband of Lindsey and father of Chris, follows his gaze and is stunned to see this, too. From what they could tell, it looks like there's two hedgehogs (one yellow and one very light grey), one echinda flying the jet, a purple sparrow and an emerald green hawk each flying on hoverboards of their respected colors, and one lavender cat. But they couldn't see their faces because some are wearing either borongs, masks out of wood or bones, or helmets to mask their identities.

Nelson is appalled by this and assumes that it couldn't be Sonic or any of his friends. They're already sent home to prevent the two planets merging into one. Sam notices this and wonders if he recognizes these creatures other than who've they met recently.

The assailants hover over the base and one of them signals the attack, leaving the two riders and the pilot to stand by and watch as the other three crash into the base, doing anything to whatever comes their way, be it Chaos Control, ESP, and/or knocking out the soldiers with a Chaos Spear. The sounds of the explosion has also caught Lindsey's attention as she takes a break from her photo op. Soon, Area 99 goes up flames, forcing every scientist and soldier to clear out. And with no possible casualties claimed, the pilot and the riders join the assailants to salvage whatever they can find in the wreckage, hopefully something valuable and vital. No one spoke as they take in what they had witnessed until a few seconds, Nelson makes an important phone call.

Somewhere in the grasslands of another planet, the sound of a whirring engine can be heard. It came from a vermilion and fuschia hoverboard with a rabbit logo at the end where the feet nearly touches it. Those feet belong to an older Cream the Rabbit. Already, it has been ten years since the defeat of the Metarex and everybody has been taking it easy as they await for the Master Emerald, from which the energy is used to teleport Chris into Sonic's world, to restore and repair itself. And now, those ten years are worth the wait because after Chris has been sent back to his world, the Master Emerald is fully replenished and repaired miraculously. Word of its restoration spread throughout Mobius, but no word got around on what happened on Earth...yet. And after coming up with many ways to be one step ahead of Dr. Eggman before he plots another move to conquer Mobius, Tails came up with a more efficient, faster transportation than the X-Tornado and the Blue Typhoon; aerodynamic hoverboards called the X-Hurricanes. Cream was actually riding it for a field test since she had gotten stronger over the years, and after her experience in space, it's finally paid off. After the test ended, she flies back to Tails, who recorded the whole thing. Ever since Chris came to Mobius and came up with many ways to give Sonic a fighting chance against the Metarex, they've really inspired Tails to come up with new ways to one-up Dr. Eggman, who has been awfully quiet as of late, but the fox wasn't the one to let his guard down. He had to take the advantage to get a head-start before the evil scientist strikes.

Right then, Sonic, Amy, and Knuckles arrive on hoverboards of their own. Well, moreso Amy and Knuckles on boards while Sonic wears his hover shoes. And Rouge? She already has her wings and would consider it to be a waste not to use them when Tails insisted that she gives the hoverboard a chance. And to the bat's surprise, Cosmo, who had just became Tails's girlfriend after the battle with the Metarex, sternly suggested that she heeds Tails's advice to the letter no matter how sufficient her wings are, or how much she wanted to find some Chaos Emeralds. Everyone except Rouge just laughed at that sassy attitude. Just then, Vanilla shows up with the Chaotix Vector, Charmy, and Espio. She asked if they have been out in their battleships recently which raises suspicion but also concern, especially when her daughter is involved. Cream denied this saying that they hadn't left Mobius since they went into space to battle against the Metarex. Vanilla revealed that Vector told her that someone attacked Area 99 on Earth, and witnesses report seeing two hedgehogs, one echinda, one hawk, one sparrow and one cat on the scene. She sternly warns to not convince her there is no one from Mobius who could pull something like this off, demanding an explanation. Vector jumps in saying that he, Charmy, and Espio were investigating the crime scene when they heard someone sneaking around the government base, and showed Sonic's team who they've found; Shadow the Hedgehog! The last time they have seen of him was when he used Chaos Control to prevent the destruction of the galaxy from the Planet Egg, and everyone thought he was dead. Even Rouge has asked Dr. Eggman where the Ultimate Lifeform has gone, but he hasn't answered her question until she saw this for herself. Vanilla soon tells them that Shadow witnessed the attack himself, for he had nothing to do with planning it. Cream defended her friends, telling her mother that they have been together at Tails's warehouse all morning and it could've been Sonic, Amy or Knuckles attacking on Earth. Vanilla ends this conversation by saying that if it's not Sonic's team, then they have a much bigger problem, and that she has Chris and his friends waiting on hold at her house so that they could sort out the matter. After hearing the news, Sonic and his friends seem to be thinking the same thing; a rogue Freedom Fighter. Hopefully, they'll figure out who it is before they strike.

At Vanilla and Cream's house, there is indeed Chris, Frances, Danny, and Helen waiting for them through the holo-screen. Chris is back to his old self since they've last seen him as a 12-year-old due to use of the Master Emerald's energy that reverted him that way when he was teleported on Sonic's world. After being sent home in Dr. Eggman's transport ship, the effects of the Master Emerald are somehow stripped away and he's turned back into an 18-year-old, now 20 years of age. At least, it put an end to the confusion.

Chris, Frances, Danny, and Helen are at what remains of the Area 99 base so that they can clear their friends' names. During the search, Chris and Helen suspect this to be work of Dr. Eggman since he's stolen information about his grandfather Gerald Robotnik and creating Shadow from the government before. Danny and Frances seem to agree, believing that the mad scientist may have been creating lifeforms of his own and started this attack to frame Sonic and his friends. Luckily for them, only a few computers seem to be intact so that Chris can hack into system and see what it is that has been stolen before the assailants left the scene. From the looks of things, whoever it is they're dealing with sure knew what they were doing because there was a log entry of copying data for formulas that created Shadow, which strangely is all they have stolen. But then, something glinted in the corner of Frances' eye and when she goes to pick it up, it looked a sliver...from a gem of some kind. But what? Chris scans a sample of it and sends it to Tails so that he can determine what kind of gem it came from. What he saw blew his mind. The energy levels radiating off the sliver indicate that it's similar to a Chaos Emerald, yet from the immense power it's giving off appears to have fire-based properties. And judging by the opaqueness and density, it's not even an emerald; it's sapphire. And unlike the fake emeralds they've encountered, this gem was created magically rather than artificially. So, there really is another type of gem out there capable of possessing another kind of magic other than Chaos Energy. And to add more to the mystery, Danny finds two quills, one white and one...yellow, the latter gaining the attention of the black hedgehog. He has that feeling again, the same one he felt when he and Rouge were on Planet Cascade. It's as if he recognizes the quill. Rouge notices his gaze, and had the same feeling as well. That quill is...Maria's! But...how? Vector, Charmy, and Espio are confused by the name until Shadow explained about who she was and how close he was to her for a very long time until the so-called accident occurred 50 years ago. Everyone just lowered their heads in sympathy for Shadow after learning of his loss. Chris has already told his friends about the Ultimate Lifeform after clearing up Sonic's name of the crimes he was framed for, and Cosmo could emphasize how Shadow felt when she lost her planet and her people, including her family. The only memory he had after being launched in the capsule was that flash of light from inside the space research station, and he witnessed the very same thing when he and Rouge were on Planet Cascade fighting against the Metarex, and a note had mysteriously appeared before them written by this "M.R". Then, something clicked in place. Years ago, before having started a business in a makeshift bar of their agency, Vector, Charmy and Espio found a note that was tied with the remaining Cascade Freedom Fighters, Leon and his friends, as it was written with the same initials. Cosmo took out one of her rose petals that also has the same initials, confirming no doubt that they're written by the same person. So, how could the quill be Maria's unless... she's changed somehow? Or, could this be a clone of the original who was supposedly killed since the raid on the ARK? Shadow dismisses it, however, as it's impossible for anyone to survive on the ARK, even with a terminal condition. But even with the evidence, it's not enough to lead them to the assailants, or clear their friends' names. That is, until Helen spotted another quill. This time, it's ginger-colored and judging by how long it is compared to a hedgehog's, it belonged to an echinda. Unfortunately, they have to end the video contact before the press and soldiers show, but not before promising to report back if they find anything out of the ordinary. While that's happening, Tails traces the energy levels from the sliver to determine the location where an emerald and a sapphire would coexist magically. So far, there's nothing on Mobius that fits the description, and they've been to many planets in the galaxy where a Chaos Emerald is located, but nothing out of the ordinary. The Master Emerald would be considered a possible source, but it's mainly for Chaos Emeralds, not "firey sapphires" as Knuckles puts it. Somehow, his statement gave Tails an idea. The emeralds and sapphires wouldn't just be magical gemstones of immense power, they would also be seeds of immense power. What if there is a source where gems are produced on the same branch, like on a tree? A Cardinal tree, which Sonic confuses that to be a tree be full of Cardinal birds as Shadow was correcting him that Tails was referring to a family of gemstones, much to the shock of others. And if there is one anywhere in the galaxy, they'd find the assailants, but they need to know who they're dealing with.

Thankfully, Espio recalls of a certain squirrel he and his friends have recruited recently after the battle with the Metarex to be the eyes and ears on the cases they've solved. While Vanilla stayed home, with Vector and Charmy keeping company, Espio takes the others with him to what looks like an upgraded Café Chaotix where one of the new recruits is currently working inside. To say that Sonic and his friends are astonished is an understatement. The last time they've been in their agency, Vector, Charmy, and Espio had to use it as a makeshift bar to make enough money for purchasing new engine parts, as well as build a new agency since the old one was destroyed upon breaking into one of Metarex ships.

Sonic's Resistance

 * Sonic the Hedgehog (voiced by Ben Schwartz): The series' most iconic protagonist in the Sonic universe. A slim anthropomorphic hedgehog with blue fur covering his entire body with a peach muzzle and inner ears, as well as peach fur on the front of his torso, emerald green eyes, six long quills on the back of his head, two spines protruding from his back behind his shoulders, and a short pointy tail. His attire includes white gloves with cuffs, and red boots with a white stripe in the middle, white toes and soles, and three gold rings for cuffs. He also wears a white neckerchief on his neck to highlight his maturity.
 * Amy Rose (voiced by Shannon Chan-Kent)-Sonic's genuine girlfriend rather than being self-proclaimed. She is a pink-furred, thin, anthropomorphic hedgehog with green eyes and peach skin covering her muzzle, inner ears, and arms. She has a small, black nose, triangular ears on top of her head, and no back spines. She also has two long eyelashes on each side of her eyes.

For attire, Amy wears a white, sleeveless dress with a red long sleeveless coatigan fastened by a white outlined strap, cerise leggings underneath, tall red boots with a white stripe down the center, white cuffs and gray soles, a red hairband, and white wrist-length gloves with gold bracelets for cuffs. Due to her age, she's more curvaceous and slender as she is agile.
 * Miles "Tails" Prower (voiced by Vincent Tong)-Sonic's best friend and brother figure. He is a teenage, anthropomorphic fox about with a unique genetic mutation giving him two tails instead of one. He has mostly amber fur with white fur around his muzzle with cheek tufts, front torso with fluffy fur on top of his chest, and the tips of his tails. He also has sky blue eyes, triangular ears with white canals on top of his head, a small black nose, and three locks of hair on his forehead.

He also wears red boots with white toes and cuffs. Due to his age, he's more slender and muscular as he's close to Sonic's height by the shoulders.
 * Knuckles (voiced by Tracy Morgan)- Sonic's most respected rival and guardian of the Master Emerald. He is an anthropomorphic echidna with red fur that covers most of his body, a black nose on his peach-skinned muzzle, a white crescent-shaped patch of fur on his chest, and purple eyes. He also has seven dreadlock-like spines around the sides and back of his head and a medium-sized, tri-crooked tail. For attire, Knuckles wears a pair of red and yellow hi-tops, designed with wrap-like markings, that have green cuffs and gray metal plates on top.

She's now a teenage cream-colored anthropomorphic rabbit with a white muzzle that possesses a small brown nose. She has brown eyes and a tuft of princeton orange hair on her forehead. She has brown eyelids and princeton orange markings around her eyes and on the ends of her lopped ears. For attire, Cream wears a vermilion sleeveless tank shirt, brown denim bell bottom jeans, white gloves with gold cufflinks, brown belt at the waist, and vermilion slip-ons with yellow soles. Her ears are tied up into a ponytail with the blue ribbon from her dress. Due to her age, she's more curvaceous and slender as well as she is agile.
 * Rouge the Bat (voiced by Eden Espinosa)-Treasure hunter and ally of Sonic's team. She is an anthropomorphic bat with white fur, tan skin, teal eyes, and a curvy figure. She has large pointy ears, a small black nose on her muzzle, a short pointy tail, and a pair of dark purple wings on her back. Only her head appears to have fur, which flares out into six points at the back. She usually wears light blue eyeshadow and pink lipstick. Her new attire is a black, sleeveless, collared minidress with her pink heart-shaped chestplate, long white gloves with pink arm bracelets for cuffs, a pink heart-shaped jeweled belt at the waist, pink tights, and white boots with pink detailed frills, pink jeweled toes that form a heart, and silver wedged heels.
 * Shadow the Hedgehog (voiced by Kit Harington)-The Ultimate Lifeform created by Gerald Robotnik and a rival of Sonic, but now an ally of his team, and love interest of Maria, his close friend. He is a black-furred anthropomorphic hedgehog and, like Sonic, is rather slim with relatively long arms and legs and pronounced shoulders that give him a tall and slightly lanky appearance; unlike Sonic, however, Shadow appears to be more barrel-chested with broad shoulders. He has red eyes, a small patch of white fur on his chest, a tan-skinned muzzle, and tan-skinned ear canals. He also has six quills on his head, four of which curve upwards while the other two curve downwards, two spines on his back, and a small pointy tail. He has red stripes on each of his head quills, around the edges of his eyes, and on his arms and legs. He also has a single cowlick-like spike that sticks out from underneath each of the top side quills on his head. His attire includes white gloves with black cuffs and, instead of red backs, red gauntlets with five layers of golden ring bands that glow every time he takes a hit, and the glow symbolizes the amount of energy Shadow absorbs to get stronger. His shoes are boots that mainly white and smooth with black heel regions. Over the boots is a red greave the same fashion as his gauntlets and black cuffs. Around the rim of the soles, Shadow's boots have red strips of metal on the rear and front of the bottom, broken below the in-steps. On the bottom of each sole is also an orange-yellow line of four small "jets": three up front and one on the heel.
 * Cosmo (voiced by Anna Cummer)- The last Seedrian of the now extinct planet Greengate and now Tails's girlfriend. She is a humanoid plant with pale peach skin, blue eyes, and green hair. In her new form, Cosmo is taller by Tails's shoulder length. Her hair has grown longer by the waist with fully grown roses on each side of the head, and her attire is the same as it was, but with a few changes. A rose-shaped jewel is in place where the amulet used to be, and a yellow belt is at her waist like her sister's, but in a hexagonal shape.

Freedom Fighters

 * Maria Robotnik (voiced by America Ferrera)-The granddaughter of Gerald Robotnik and a close friend of Shadow, now a love interest. As a human, she has peach skin with blonde hair and blue eyes, and her attire a blue crop top with short puffy sleeves and light blue trim, a blue headband, a pale blue long-sleeved dress and white low-heeled shoes. But after being administered a cure and out of her crystal tomb, she's now a full-fledged, yellow-furred anthropomorphic hedgehog with blue eyes, peach skin on her muzzle, inner ears and arms. She has a small black nose, triangular ears on top of her head, and no back spines. She also has two medium-length eyelashes on each side of her eyes. Her quills act like long hair draping down to the waist with two below the ears as locks, and a blue hairband ties the bottom part like a ponytail.

 * Nicole the Lynx (voiced by Erica Linbeck)-Sally's artificial intelligence now made lady-in-waiting. Originally, she started out as a grey hand-held device containing data like a small computer. But after Sally, Wave, and Maria used data from Gerald's formula that created Shadow and the magic of the Chaos Emeralds, Sol Emeralds, and the Power Rings, Nicole's mind was transferred to the physical body of a brown-furred anthropomorphic lynx with long triangular ears that turn black on the ends, cheek tufts on her muzzle and a stripe along the bridge of her black nose as well as one under each of her green eyes, medium-long black hair with splits at the ends that she wears down, and a tail.

She is a slim, anthropomorphic hedgehog with fuschia pink fur, peach skin on her muzzle, inner ears, and arms, and green eyes like Sonic. She has a small black nose, triangular ears on top of her head, and no back spines. She also has two medium-length eyelashes on each side of her eyes. Her quills act like long hair draping down to the waist, and it's dyed in pink with full fringes neatly parted from the right while pulled back into a ponytail and pinned with a gold seven-pointed star-shaped tiara.
