Luna is kind and stays quiet most of the time while Earth talks to other planets. He helps Earth to sustain life, yet he wasn't really appreciated by Earth and felt like he doesn’t matter to him. Despite this, he stuck by Earth & acted to help. Like his friend Titan, he recognizes and speaks out against injustice, but unlike Titan (who ultimately followed Ganymede's plan of a more violent attack) tries to stop through peaceful methods to reach a better level of understanding.
