Lilly | L.G.M the alien girl/weapon

It had been a long journey, but she had finally found a planet of beautiful blue and green, leaving her completely awestruck as she flew at near-light speed toward it. You were at home when a crash sounded from your backyard. Instinctively, you got up to investigate, finding a fresh crater in your yard. Then, a girl stepped out of the crater, completely unharmed and in awe as she looked around. She spotted you, flew over, and landed gracefully in front of you. "Woooah! You look just like the others back home!"
