Thank you all for your friendship. Before I met you, I didn't believe in myself. My clan was wiped out by the Metarex. I felt like I was helpless and couldn't do anything to stop them. But because of you, I learned that I didn't have to stand by and watch the Metarex take over. I could do my part to fight back and help restore my clan. I just wanted you to know that I'm happy now because I fulfilled my destiny. Remember, I'll always be with you.

— Cosmo, "So Long Sonic"

Cosmo (コスモ, Kosumo^?) is a character that appears exclusively in the Sonic X anime series. She was a female child of a plant-like alien species whose home world was destroyed by the villainous Metarex, who, in the time that followed, left Cosmo as the sole survivor of her kind. To thwart the Metarex's ambitions for universal dominance, Cosmo joined Sonic the Hedgehog and his allies in their war against the Metarex, eventually becoming a love interest for Miles "Tails" Prower. However, in the end, she sacrificed herself to defeat the Metarex for the greater good.

Appearance

Cosmo is a short and humanoid plant-like alien with pale peach skin and powder blue eyes with one long eyelash on each one. She possesses short bright green hair with two bangs and a pair of paradise pink rose-like flower buds held by golden hair ties on each side of her head. For attire, she wears a green coat with golden trim at the bottom and cuffs, a white petal-like skirt with bright green tips, a paradise pink amulet, white tights and green ballerina flats.

History

Past

Cosmo's former homeworld was destroyed by the Metarex before she was born, and she was instead raised on a space colony. She lived peacefully there until the Metarex came and began to destroy her new home, including her family (which included Earthia). As Cosmo was escaping, the Metarex planted a tracking device on her. Cosmo also had a device inside her brain, which when activated, allowed the Metarex to hear and see everything that she did, allowing them to always be one step ahead of their enemies.

Metarex Saga

Cosmo being founded by Tails.

Cosmo landed on Sonic's planet to look for Sonic the Hedgehog. When she arrived, she is found by Amy Rose, Miles "Tails" Prower, Cream the Rabbit and Cheese, who were nearby to watch the falling stars. Cosmo wakes up and finds herself at Cream's house, surrounded by her rescuers. Unfortunately, Metarex Carrer followed her and started destroying the forest. Cosmo joined Tails in the X Tornado to assist him by providing him advice. Then, when Sonic arrived, Cosmo hurried to meet him. Metarex Carrer unearths the Planet Egg and leaves with it. Cosmo then leaves Hyper Tornado to finally meet Sonic. She tells her name and makes the request to defeat the Metarex. Without the Chaos Emeralds, Sonic could not do anything. Fortunately though, Chris arrives on Angel Island and Tails built a giant spaceship named the Blue Typhoon. Cosmo helped Amy, Cream and Cheese provide items and food, until Metarex Spike arrived to finish Metarex Carrier's work. The girls then went aboard the Blue Typhoon. Metarex Spiker was then destroyed by the Sonic Power Cannon.

Cosmo comforting Knuckles

The Blue Typhoon landed on Hydo Planet to look for the first Chaos Emerald. However, Sonic and Chris went missing. While waiting for them, Cosmo helped in the research for the Chaos Emerald. She fell asleep under the sun, but brutally wakes up. Cream and Cheese found the Chaos Emerald, and Sonic and Chris were back. A party was launched in the place and every member was invited except Knuckles. Cosmo joined in. Before going back in space, Knuckles comes back with Dr. Eggman (who was also looking for the Chaos Emerald). Despite what everyone says to him, he still takes the Chaos Emerald. Cosmo tries to convince Sonic and Knuckles not to fight, but nobody listens to her. The Egg Mars then appears to take Cosmo hostage and force Sonic's crew to give up on the Emerald. Cosmo was finally released by the Egg Mars and caught by Knuckles.

Cosmo joined Sonic, Knuckles and Chris to look for the second Chaos Emerald, which appeared to be a fake one. During their investigation, Cosmo tries to communicate with a tree, which died due to the Planet Egg being lost. She then promises to find the Planet Egg and restore the planet. Amy's words revived her Cosmo's determination, so she joined Amy, Cream and Cheese in their researches. Every time Cosmo activates Metarex Kingape's traps, it was up to Amy, Cream and Cheese to free them all. This time, Cosmo attacks Metarex Kingape by throwing tomatoes at his face. The girls attacks him all in one to escape, but Metarex Kingape found them. Fortunately, they met Sonic, Tails and Knuckles on the way, but also Dr. Eggman, Decoe and Bocoe. Everyone was trapped in growing roots until Chris rescued them.

While Knuckles and Sonic's absence, Cosmo and the remaining crewmen guarded the Blue Typhoon. When an unknown spaceship approaches, they think the visitors are Metarex and attack them. However, the visitors are the Chaotix detectives. To forget this misunderstanding, the Chaotix were invited for coffee. Cosmo does not miss Vector and Cream's conversation. She kept an eye on Vector until she catches him in the kidnapping act. Fortunately, Sonic returned and went looking for the girls. Cosmo stops a battle to start by yelling at Sonic and Chaotix that only Cream had to decide to stay or leave. Chris approves. Cream decides to stay aboard and pursue the space travel.

Cosmo and Chris team up to search for the Chaos Emerald hidden on Planet Hobidon. During their investigation, Cosmo activates a record. The Hobidon shown explain how dangerous the Metarex are. When the record stops, Cosmo concludes that the inhabitants are dead, so she stays silent to commemorate their death. On the other hand, she learns from Chris about Shadow, who sacrified to save the Earth. While Shadow's return shocked the crew, it is Cosmo's turn to face her nightmarish return of Scarship, who killed her people. Despite seeking vengeance, she does not want to involve her comrades, so she approves Tails and Knuckles' decisions to retreat. Sonic explains that this had to happen again soon or later, and everyone will fight the monster ship. Cosmo thanks everyone. The Blue Typhoon was about to collapse with the Blue Typhoon, when Shadow appears to rescue the Blue Typhoon. Thanks to his help, Scarship is defeated by the Blue Typhoon.

Tails comforting Cosmo.

However, Cosmo was still haunted by Scarship's attack on her colony and her older sister's screams, but didn't know why. She tags along with Knuckles and Tails to search for the fifth Chaos Emerald hidden somewhere underneath. Cosmo and Tails were separated from Knuckles and lost in the underground cave. The two of them discover a secret base guarded by Metarex Vipers and where the Chaos Emeralds are copied. Tails copied the datas and escaped the base with Cosmo and the real Chaos Emerald. On the way out, Cosmo blames herself for putting everyone in danger because of her hate and sadness towards the Metarex, but starts experiencing the power of friendship. She tags along with Tails to help Sonic fighting off all of the Metarex Vipers.

In order to enter the Metal Plant, the Blue Typhoon and the Crimson Egg crews had to team up. However, Decoe put under Amy's Spaceship, causing Amy to lose control of it. Thanks to Knuckles, Amy took control of her spaceship and drives it to the Chaos Emeralds. The threesome is greeted by an hologram of Dark Oak. Cosmo tries to communicate with it, but the hologram only orders to kill them. In order to save Sonic and Amy, Cosmo enters the code to free the Chaos Emeralds, causing the Planet Egg to fall in space. Red Pine's armada then appears to finish the job by shooting at the Metal Plant to destroy it, along with everyone inside. Cosmo returned to Blue Typhoon, while Super Sonic and Super Shadow are arguing about the Chaos Emeralds.

Cosmo decided to throw a party, to enable everyone to relax after what had happened earlier, but planned to keep it secret. Unfortunately, Tails discovers it, but also the Chaotix. Vector says that he wants to help them to throw the party, which makes Cosmo think that he changed, but it's not. Indeed, Vector planned to make Cosmo fall in love with Tails. Cosmo and Tails thwarts every single plan. It was until Tails protected Cosmo from being crushed by the disco ball that everything changed between Tails and Cosmo. Unfortunately, though, Knuckles destroyed the party in rage. Cosmo falls in despair, but Sonic decides to throw the party anyway. Cosmo smiles.

Sometime later, the Blue Typhoon enters the gravity field left by the Metal Plant to search for the Chaos Emeralds again. Inside, it cannot pass through the giant rocks. Yellow Zelkova then appears to kill the intruders. Sonic and Knuckles distracted him, so the Blue Typhoon could pass. The crew was greeted by Black Narcissus through a message saying to send him Cosmo in exchange of their survival. While everyone disagrees, Cosmo decided to meet him anyway, in order to get answers. However, Chris saw her leave and decided to go with Cosmo to protect her. When Cosmo arrived, she orders Black Narcissus to tell everything he knows about the Cosmo Tribe and the Metarex, but the robot-king just wanted to track the Blue Typhoon to her. Chris interfered, but nothing changed. Cosmo and Chris were hold hostages but were freed by Shadow. Cosmo then drives Amy's Spaceship back on Blue Typhoon.

Cosmo, Cream and Cheese joining Amy to have fun with her.

On Planet Marmolim, Cosmo learns from Ghana that she could be a threat to everyone by her acting, no matter what. Despite that, Cream and Cheese tell Cosmo that their friendship will bring good changes throughout the universe. Cosmo then recovers her self-trust, subsequently proving that she can be helpful and trustworthy. She, indeed, helps Tails regaining his self-trust by telling him the crew needs him more than anything and cannot stand without him. Sonic approves by saying that he has faith in Tails and will listen to him no matter what. The Blue Typhoon had to land on the nearest planet around to get supplies. Cosmo and Tails are waiting for the other crewmen, who take long to come back. Meanwhile, Pale Bayleaf followed the spaceship. Dr. Eggman fainted to have defeated Sonic in order to help the Blue Typhoon to leave the planet. The lure succeeded and the Blue Typhoon could leave. It is attacked by Yellow Zelkova again, overpowered by Dr. Eggman's technology and a new armor.

The truth is finally revealed by Yellow Zelkova's death and Cosmo's true identity. Shadow and Rouge raid the Blue Typhoon to kill the Metarex spy who reports everything. Sonic, Knuckles, and Tails fights Shadow to keep Cosmo safe. As he was about to murder Tails, a mysterious Metarex breaks through the Blue Typhoon to steal the last Chaos Emerald. The Metarex mothership then appears; Dark Oak's voice congratulating Cosmo; a.k.a. White Seed for having accomplished her mission. Cosmo is brought back in time, when Metarex Hellship attacked her space colony. She remembers that she made a pact with Dark Oak in exchange to stay alive. Everyone ended up learning about that, but still keeps considering Cosmo as innocent. The latter decided to leave the Blue Typhoon to fight Dark Oak alone but was stopped by Tails and their friends. On the other side, Dr. Eggman sends a call to tell where the Metarex are going. Still Cosmo feared to put everyone in danger if she stayed on board, but Tails convinces her to stay and live with them once the battle over. Cosmo tearfully replies by a simple "Thank you, Mr. Tails."

After Sonic was swallowed by Dark Oak and sunk in the Aquarius, everyone was losing hope, but Cosmo explains that Sonic sacrificed himself to protect them, so everybody should help him in return. Her words revived all the fighters' determination to pursue the battle and take Sonic back. Meanwhile, Dark Oak could still hear everything, so the Final Mova proceeds to destroy the Master Emerald. Shadow, the Crimson Egg and the Chaotix detectives work together to give Knuckles time to ask the Master Emerald to give its full power. Tails then launches the Sonic Power Cannon at the Final Mova, killing Pale Bayleaf and Black Narcissus in the process, and Amy brought Sonic back.

Cosmo and Tails' final goodbyes

When everything seems lost, Cosmo receives a call from her mother, Earthia, who tells her that her time to shine has come. Cosmo then turns to Cream and Cheese to repeat her mother's message and starts to fly to fulfill her destiny. She breaks her red crystal to change herself into an adult and stop the Aquarius' explosion. She then enters the Planet Egg to take control over it by transforming into a gigantic cherry blossom. Cosmo's spirit then appears to inform them that the moment has finally come to stop the Metarex and save the universe once and for all. Unfortunately, Tails is the one in control of the Sonic Power Cannon and he refuses to kill her. But due to Dr. Eggman's speech and Cosmo's spirit appearing again to apologize to him, he reluctantly agrees. Tails tells her that she never caused problems, but Cosmo's spirit then makes the wish to shoot. Tails tearfully launches the Sonic Driver. Cosmo and Tails' souls meet one last time to exchange their goodbyes to each other and the promise that they will never forget each other . Cosmo's soul then ascends into Heaven while saying to Tails that she loves him (in the dubbed version). In the subbed version she tells Tails that she will always remember him.

Cosmo's seed, "So Long Sonic".

Cosmo's spirit reappears to thank everyone for everything and to say that she will be with them forever. During the Planet Egg extraction with a Chaos Regeneration, Cosmo's heart (in a white seed form) was found by Sonic and given to Tails. The fox cub breaks down in tears, accusing Sonic to have failed to save Cosmo. Back on his planet, Tails planted Cosmo's heart in a pot and took care of it like his own heart. A month later, two small green leaves sprouted. On a sunny morning, Tails has to leave his workshop to stop Dr. Eggman once again.

Personality

Cosmo is a kind and gentle individual, although she often feels guilt, anger, and overwhelming sadness due to being unable to save the rest of her species from destruction at the hands of the Metarex. She also seems to suffer from low self-esteem, often calling herself "unworthy" or blaming herself for the hardships that she and her friends had to endure. Cosmo can be somewhat clumsy, but she is also quite resourceful. She will often rush headfirst into danger with little sense of self-preservation, even into situations that she knows to be a trap, which can be put down to her survivor's guilt spurring her to sacrifice anything to atone for saving herself while her family perished at Dark Oak's hands. Cosmo strongly dislikes violence and the need for conflict in life, like her father in many ways, but unlike him, she acknowledges that fighting is sometimes a necessity and that struggle and conflict are a necessary evil to achieving a better future.

Powers and abilities

Cosmo does have a few abilities, such as being able to empathize and communicate with plants, trees, or the planet itself and determine their state of life. Cosmo can jump very high and use her skirt like a parachute to gently float down. She also appears to be able to unlock the power of a Planet Egg, as demonstrated in "Desperately Seeking Sonic," where she caused the Planet Egg to activate and grow vines that entangled Dr. Eggman's machines, but also her friends and herself due to her lack of control over the vines. At the end of "The Cosmo Conspiracy," Cosmo's amulet begins to glow before she teleports the Blue Typhoon away from Dark Oak and back to her home planet, Green Gate, though this ability is never explained afterwards and caused her to faint from the strain.

In "Galactic Gumshoes," Cosmo has demonstrated some sort of agility as shown when the Chaotix were about to leave and kidnap Cream with a sack, she quickly rolled next to Cream letting herself get captured along with Cream and later on when Vector and Cosmo get into a fight, she is able to avoid his attacks with speed and thus gained the upper hand. She also shows heavy endurance as she is able to recover from powerful attacks quickly as seen in "Desperately Seeking Sonic", where she quickly arrived back to attack Metarex Kingape with fruits after being sent flying into the air by a heavy branch shaped like a club. She is able to read and decipher the Metarex language, either due to the implant in her brain or their shared origins on Green Gate.

Transformation

When Cosmo removes her amulet she can enter a transformed state, wherein she is able to turn into a tree and fuse herself to Final Mova. Presumably she is able to bond to machinery in this form as Earthia did with their ship's navigational system, and in the dubbed version it is heavily implied to be the form her species must take to birth children. Eggman describes this state as what happens when a member of Cosmo's species reaches maturity, though it causes them to "wither and perish" immediately afterwards if they are not sustained by artificial Planet Egg energy as her mother was on their ship.

Weaknesses

Cosmo's weaknesses include being physically weak and acting a little clumsy. She has trouble carrying heavy objects but can use certain objects as defense. Cosmo also tends to get into trouble easily due to her survivors guilt. She also might have air sickness as in her debut episode, when Tails was flying high above Angel Island, she was shown to be very dizzy and in "Station Break-In," when Amy was trying to catch up to Sonic, she sped up her ship but Cosmo was not feeling well so Amy held back.

Relationships

Earthia

Earthia is Cosmo's mother who is the leader of the Green Gate council. She decides to leave the planet when it becomes too dangerous, but she is later killed after the Metarex board her refugee ship. During the series finale, she appears to Dark Oak—now returned to his form as Lucas—and speaks with him, telling him that thanks to Cosmo they now have 'another chance' together; however this dialogue appears only in the dubbed version. Though originally incensed by Earthia's murder at her father's hands, Cosmo comes to see her mother in a much less innocent light after learning that it was her spiteful actions on their home planet that created the Metarex, although this aspect of their relationship appears only in the Japanese version.

Galaxina

Cosmo and Galaxina.

Galaxina is Cosmo's older sister who worries a great deal about Cosmo and Earthia. She is very smart, sophisticated, and down-to-earth, the opposite of the dreamy Cosmo who appears to perhaps be the eldest—or most authoritative—of the family who are shown in the beginning of Episode 77, while Cosmo is an 'infant'.

Dark Oak

Dark Oak is Cosmo's father. She has a strained relationship with him, as Dark Oak would treat her more like a subordinate than a daughter. Due to this, Dark Oak would be willing to fight Cosmo should she get in his way. Cosmo herself despised her father's deeds and turned on him. Nonetheless, on learning of her father's tragic origins Cosmo comes to empathize with Dark Oak somewhat, and recognizes him as the last remaining member of her family. In the Japanese version, Cosmo eventually mourns the fact that she and her friends learned to see past their differences yet she cannot do the same for her father - questioning if he genuinely hates animals as much as he claims or if his actions are nothing but revenge against her mother. On attempting to restore the Chaos Emeralds, Cosmo attempts to reason with Dark Oak, debating her hope that their species can coexist with animals one day against his jaded cynicism that her dream is impossible to achieve.

Miles "Tails" Prower

Tails and Cosmo watching the moon.

Don't be sad, Tails. Whenever you miss me, just look for me right here beside you.

— Cosmo, "So Long Sonic"

Cosmo became good friends with Sonic and friends, but most particularly with Tails. The two of them ended up alone on a mission together at one point when Tails got hurt, Cosmo stitched his bruise and Tails blushes in return. Later on, when the Blue Typhoon meets the Chaotix for the second time; in return for Tails repairing the Chaotix's Spaceship, the Chaotix noticed that Tails is starting to have an affection for Cosmo so the trio tried plans to join the two together in love. Although those plans failed, Tails and Cosmo's relationship seemed to be more intimate, even to the point of Tails attempting to give her a complement regarding her beauty, but did not have the courage to completely say it and Cosmo misheard it, thinking about something else.

Their love for each other is confirmed in "The Planet of Misfortune" when the Blue Typhoon lands at Planet Marmolim. There, Cream inquires about Cosmo's future and the fortune teller states that there is romance in her future. She also says it is strange since "plants and animals do not usually get along," which foreshadows future events throughout the series between Cosmo and Tails. Although Amy has set-up a trap to lure Sonic into the lake, Tails and Cosmo accidentally trigger it themselves, leaving the duo in love for each other while watching the moon, much to Amy's disgrace.

Tails later protected Cosmo when Shadow targeted her for assassination. Tails continued trying to stop Shadow even when he was very badly injured by him. In "A Fearless Friend," Cosmo plants herself on Dark Oak (in her metamorphosis form) to immobilize him, telling the heroes to fire the Sonic Power Cannon at Dark Oak, however, this would also kill her, much to everyone's dismay, especially Tails'. In the Japanese version, when it's up to him to fire the Cannon, Tails was extremely hesitant to do so and had a brief emotional breakdown, but with the help of Eggman's reassurance, Tails screams his love for Cosmo just before he fired the Sonic Power Cannon. In the English dub, he never directly stated such words; it is strongly implied that Tails simply did not have the courage, even at the end, to admit that he loved her. When Cosmo's spirit visits Tails she kisses him on the lips. In response, Cosmo says in the Japanese version that she will always love Tails before ascending in Heaven, while in the English dub she said that she will never forget him.

Amy Rose

Amy Rose is one of Cosmo's best friends. At first, Amy despised Cosmo when she announced that she had crossed space to find Sonic and threatened her not to approach him since she claimed to be his official girlfriend. In the end, Amy recognized Cosmo as a tragic victim and agreed to help her rescue the worlds which the Metarex conquered. During the trip, Amy encouraged Cosmo to go through with her choices and fight to achieve her goal. She later mourned her sacrifice against Dark Oak.

Cream the Rabbit

If a friendship like ours is rare, that makes it extra special!
Chao!
I feel the same way as you both do!

— Cream the Rabbit, Cheese and Cosmo, "The Planet of Misfortune"

Cream the Rabbit is another of Cosmo's best friends. From the beginning, she liked her and surprised her with her optimism. Cosmo enjoyed spending time with Cream and believed in her decision. She could also turn to Cream for advice, and managed to convince her that their mutual friendship is proof that plants and animals will be able to coexist in the galaxy. When Cosmo was in her deepest despair, Cream visited her and refused to leave her, even after learning that Cosmo was unknowingly a spy for Dark Oak.
