Description: Blue Gender is a sci-fi/mecha anime where the main character Yuji is terminally ill and is frozen so that in the future he could be saved. Although upon awakening he is suddenly thown into a future where Humans were forced to leave Earth due to Insectoid beings called "Blue" overrunning Earth. So humans developed a giant space colony called second Earth to flee from the invaders, in hopes of one day reclaiming Earth as their own.
Reason: Blue Gender was originally meant to be broadcasted on Toonami, but then was instead broadcasted on Adult Swim so I think it would fit well in here. I really liked this show because, to me it didn't give off the vibe of 'just another mecha anime'.
