Cosmo is a character from Sonic X, created by Sonic Team exclusively for the third season of that TV series. Cosmo is a female child of a plant-like alien species whose homeworld was destroyed by the villainous Metarex.
She is an ally of Sonic the Hedgehog and his friends, and it is widely accepted that her primary purpose in the series is that of a love interest for Tails, the two characters being of the same age and displaying an overt fondness for one another.
I, the undersigned, agree to having Sega making Cosmo an official Sonic character, meaning that she will be included in future Sonic games developed by SonicTeam.
