Cosmo (コスモ Kosumo?) is a main character from the anime series Sonic X. She is a female child of a plant-like alien species whose homeworld was destroyed by the villainous Metarex, who, in the years 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. In the end however, she sacrificed herself to defeat the Metarex for good.
Appearance
At the age of 8, Cosmo is a Chinese to American short, humanoid plant-like alien with pale peach skin, and powder blue eyes with one long eyelash on each one. Her figure is slender, but with slightly wide hips and a more noticeable large bottom despite being only a child. She possesses short bright green hair with a pair of paradise pink flower buds held it by golden hair ties, one 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 flats.
History
Anime
Cosmo's former home world 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 (including her mother, 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.
After the attack, Cosmo escaped into a ship and arrived on Sonic's planet. Tails, Cream and Amy were the first to find her and they questioned her arrival. Cosmo told them that she was looking for the "legendary hero that can use the Chaos Emeralds, Sonic the Hedgehog." She refused to tell them any more. Later, while in Tails' jet, the X-Tornado, she spotted Sonic and hopped out to greet him. Cosmo pleaded for Sonic to help her.
Sonic agreed to help her and he, Cosmo, Tails, Knuckles, Amy, Cream, Cheese and Christopher Thorndyke, who recently arrived on Sonic's world, began traveling through the universe in Tails' new space ship, the Blue Typhoon in search of the Chaos Emeralds which Sonic scattered through the universe during his first battle with Dark Oak.
Later in the series, Shadow raided the Blue Typhoon and attempted to kill Cosmo, Before Shadow could do Cosmo any harm, a Metarex broke in and interrupted the fighting. Dark Oak called Cosmo "White Seed" and praised her for completing her mission. Cosmo then remembered that before she escaped from her space colony, the Metarex were planning to use her as a spy.
Chris and Tails managed to locate an invisible signal and found that it was attached to her brain; if they removed it, Cosmo's hearing and sight may have been lost in the process. In the English version Knuckles said that it would have been best to do that. In the Japanese version, Knuckles yelled at Tails that there had to be a way to remove it without hurting Cosmo, to which Tails yelled back that he had no idea how to do both, assuming it was possible.
Later, in the English version, Cosmo learned that she could hear the Metarex in her head and fell into deeper despair. While she was disheartened, Chris told Sonic that he now understood why Cosmo was able to understand the Metarex language.
In episode 74, Cosmo tried to run away but was stopped. Their friends then showed up and said they were determined to defeat Dark Oak instead of risking Cosmo's hearing and sight. In episode 77, Cosmo sacrificed herself by fusing herself with the Dark Oak planet to make it weaker so that Tails, Super Sonic and Super Shadow could destroy it and save the universe. And Tails ended up shooting Cosmo with the Sonic Power Cannon, causing her to be killed in the process. According to the Japanese version, in an attempt to rescue Cosmo from death, Super Sonic and Super Shadow used Chaos Regeneration, but all they managed to produce was a small seed. However, in the English version, Chaos Regeneration is not used and Cosmo implies that the seed is her child. In episode 78, when Sonic arrived back on board the Blue Typhoon, he handed the seed to Tails.
Personality
Cosmo is kind and gentle, though she often feels guilt because she was unable to save anyone from her home planet ever since the destruction of the Metarex. She also seems to suffer from a low self-esteem issue, often calling herself "unworthy" or blaming herself for the hardships that she and her friends had to endure. Cosmo also dislikes violence, but acknowledges that fighting is sometimes a necessity, although she herself is unable to fight. Cosmo can be somewhat clumsy, but she is also quite resourceful; she also has a penchant of getting into trouble.
Powers and abilities
Cosmo does have a few abilities, being a plant herself, such as having the ability to empathize with plants, trees, or the planet and determine their state of life. Cosmo can jump high and gently float down with the aid of her skirt. She also appears to be able to unlock the power of a Planet Egg, as demonstrated in episode 58, 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.
In episode 59, 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. She also shows heavy endurance as she is able to recover from powerful attacks quickly as seen in episode 58 where she quickly arrived back to attack a Metarex 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 (most likely given to her when the Metarex implanted the signal while she attempted to escape)
When Cosmo is in her transformed state, she is able to turn into a tree and weaken other planets.
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. She also might have air sickness as in episode 53, when Tails was flying high above Angel Island, she was shown to be very dizzy and in episode 63, when Amy was trying to catch up to Sonic, she sped up her ship but Cosmo wasn't feeling well so Amy held back.
Relationships
Family
Earthia
Earthia is Cosmo's mother, who is the leader of the Green Planet council. She decides to leave the planet when it becomes too dangerous, but is later killed after the Metarex board her refugee ship. During episode 78, 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. This has brought about suspicion that they were previously in love. It also brings the possibility that Cosmo's race will regenerate, though this is unlikely.
Galaxina
Galaxina is Cosmo's older sister, whom is shown to worry a great deal about Cosmo and their mother, Earthia. She is portrayed as very smart, sophisticated, and down-to-earth, the opposite of the dreamy Cosmo. She 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'. She seems to look more like Earthia than the others. She also is one of the few to have a daisy on top of her head rather than two rose buds on the sides of her head. In the original Japanese version, she and the others on the ship had no official names in the show. In the original Japanese version, Galaxina has no name; she was referred to as one-sama ("big sister") by other members of her clan.
Miles "Tails" Prower
Cosmo became good friends with Sonic and friends. Later on, when the Blue Typhoon meets the Chaotix for the second time; in return for Tails repairing the Chaotix's space ship,
Amy Rose
Amy is one Cosmo's best friends. At first, Amy despises Cosmo when she announces that she has crossed the space to find Sonic the Hedgehog and threatens not to approach her since she claims to be his official girlfriend. In the end, she looks at her like a victim and has agreed to help him rescue the world of Métarex. During the trip, Amy encourages Cosmo to go to the end of his choices and fight to achieve his goal. She's mourning her sacrifice against Dark Oak.

Trivia
- Cosmo's face somewhat resembles Lumina Flowlight.
- As shown in Episode 59 of Sonic X, when the Chaotix attempted boarding the Blue Typhoon, everyone attacked them, mistaking them for Metarex, Cosmo included. Some highly doubt that Cosmo would attack a Metarex head on like that and think she was made to do that just because of the episode's plot, although it was probably just for humor.
- Though Cosmo has not appeared as a major character in the Sonic X comics, she has two cameos: in the issue #5, when Chuck Thorndyke talks about possibilities of extraterrestrial life and in the issue #21, where a toy in her likeness can be seen at the top of the cover.
- Cosmo's family's names are derived from astronomical terms (Cosmos, Galaxy, Earth, ecc).
