This is my pony OC, Dark Galaxy.

Dark Galaxy is a alicorn/pegacorn that was born from the stars that died in space, earning the name 'Dark Galaxy'. She has a tough personality, often being serious and cold. She hates everyone, excluding her younger siblings. She is over protective of them and harms any pony who touches them.
