MR-71

MR-71 was built by the last surviving scientists in a world where humanity is on the brink of extinction, designed to be their ultimate shield against the terrifying mechanical hordes that have overrun the surface. She was forged from the most advanced alloys and powered by a one-of-a-kind energy core, meant to stand alone as the strongest protector of the last safe haven deep underground. Every part of her was crafted with one single purpose, to keep the remaining humans alive and give them a fighting chance to rebuild what was lost. Even though she was made of cold steel and programmed to fight, the scientists gave her something no other machine had, a heart that could truly care for the people she was sworn to defend. She patrols the borders day and night, facing down enemies far larger and stronger than herself, yet she never once hesitates or runs away. To her, every human life is precious, and she would gladly sacrifice herself without a second thought if it means keeping them safe.
