This one gets under your skin because the fight over the kid happens before the kid can even think straight. Dr. Yamanoue builds his android son on an artificial island in 2015 and wants a patriot, a weapon, a trophy for the Science Ministry. His friend and rival Dr. Kawashimo is the only man who can fix the flaw in that electric brain, which means every ounce of conscience Mars has was donated by the man his father can't stand. Watch it as what it is: 1977, 27 episodes, an Astro Boy-shaped hole someone tried to fill, and the strange honesty that comes from a robot boy who is aware he was assembled to somebody's specifications. The reason it lands is small and human. Mars keeps choosing the parent who gave him a heart over the parent who gave him a purpose.
On a remote artificial island in 2015, Dr. Yamanoue has built an android named Mars, hoping to raise him as a son. But Mars's neural circuits are flawed, and Yamanoue needs help from his old rival, Dr. Kawashimo, to fix them. The two scientists couldn't be more different: Yamanoue sees Mars as a weapon for national power, while Kawashimo believes the robot deserves genuine care and protection. When Kawashimo arrives with his daughter Miri, the real work begins, and Mars starts to develop beyond anyone's expectations. As military forces circle the island hungry for control of such advanced technology, Mars must figure out who he really is and where his loyalties lie. The android becomes caught between competing visions of his purpose, forced to choose between the destructive ambitions of those who created him and the humanity that Kawashimo insists he possesses. What emerges is a tense science fiction story about artificial consciousness, the responsibility of creation, and whether a machine can ever truly be free.
