She is physically similar to Cosmo, but with teal features, and is portrayed as very smart, sophisticated, and down-to-earth - the opposite of the dreamy Cosmo. In the original Japanese version, Galaxina has no name; she was referred to as onee-sama ("big sister") by other members of her clan. She is voiced by Veronica Taylor in English. She appears to be about 12-14 years old, however this is only a guess.
