Comet came from a planet that's unknown from earth, the planet was being attacked by another planet because they wanted to rule the planet. Comet's parents sent her away in a comet shaped ship so the attackers would just think it was a comet. She crashed into earth and the fall and power from the ship made her tail split but it stays together. She misses her parents and wishes she could have saved them but its too late. The planet who attacked her was from a planet of water so she fears water thinking there hiding down there but she's met bubbles.
Comet Female friends: Butterfly's and Bubbles because Bubbles is so friendly.
