Cosmo the Seedrian

Cosmo the Seedrian (コスモ Kosumo?) is a main character from the anime series Sonic X. She was 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, eventually becoming a love interest for Miles "Tails" Prower, but she sacrificed herself to defeat the Metarex for good.

Personality
Cosmo is a kind and gentle alien, although she often feels guilty 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 also dislikes violence, but acknowledges that fighting is sometimes a necessity, despite herself being unable to fight. Cosmo can be somewhat clumsy, but she is also quite resourceful. She also has a penchant for getting into trouble.
