Cosmo is from space who's entire race was killed by the Metarex (Meh-Tuh-Rex). She's soft-spoken and kind but still loves having fun, but she still has an air of somberness and rage to her deep down due to the death of her family. Cosmo has a lot of moments of joy, but just as many moments of sadness, crying, and rage. I'm looking for a voice that captures every bit of that and can yell or scream when needed. For this one, make sure to avoid what the official dub did. The official made her sound somewhat old and exagerated her politeness. I think you should still sound young, but noticeably polite.
