Jetter Mars

In 2015 A.D., a government scientist creates an android on an artificial island, intending to treat it as his son. The robot has a flawed electric brain, prompting the scientist to seek assistance from a rival, a pacifist researcher who is also a friend. The researcher brings his young daughter to the island and installs a corrected brain into the robot, naming him Jet Mars. Mars is inexperienced and unaware of human emotions or morality. After witnessing his daughter's tear, he learns about human feelings from the scientist, who tells him that crying is a sign of weakness. Later, a malfunctioning robot causes chaos on the island, leading to a crisis when seawater floods the area. Mars is unsure how to respond until the researcher's daughter uses her special ability to stop the damage, guiding Mars to help fix the problem. Together, they save the two scientists. The girl is a robot created by the pacifist researcher. Through these events, Mars learns about emotions and doing good.
