i have seen an anime where there was an all women warrior race that was fighting an alien force. the alien force was trying to save their race and the women race. they had a big fight and one of the women warriors was left behind in ( not Gundam but a fighting suit like it) space when both the women and aliens hyper jumped away. the alien force managed to get one of the women warriors and inseminated her with an egg or something , but she got Pregnant. she managed to escape to her team but she gave birth in a few hours. they landed on a small green planet with the aliens. they had a major final battle as the woman gave birth to a boy. the boy grew to an adult really fast. the mother of the first man died in battle. the captian of the woman race told a cadet woman to escape their ship and land on the larger planet. both women warrior race and the aliens wiped each other out which left the green planet dead ( which is now the moon ). the cadet woman and the first man landed on the larger green planet( earth) and stayed there. in the end credits, you see cities and people walking all over.
