This is Nova and the Twins eldest sibling Nebula, she is older then most stars and galaxies and is a master of martial arts. Unlike her siblings that have a more weaponized power (like Solar's solar flare tail) her's is she can manipulate gravity and that's how she flies 'n junk. Her tail is actually her main weapon and makes it so it weighs about as much as a cargo ship with her power. she is my sweet princess
