Galaxy is a cute girl who protects the Super Space Station of Space Dimension from any intruders, villains or bad people in general. She isn't very strong or powerful, however, she can float and fly with her wings. She can be rather shy sometimes on rare occasions too. She is so old that she forgot her own age. She was found on an unknown planet weak and on the verge of the death. It was thanks to the leader of the Space Station, Rei Stellaris that she is alive and well.
