Thanos's father is a famous scientist in charge of Titan. When Thanos was born, her mother saw the death in his eyes and wanted to kill him at once, but her father stopped her. Since then, my mother has been afraid of Thanos.
When she was a child, Thanos was always lonely because of her ugly face, but she gradually integrated into the group. That's right. Thanos is just a pure boy who wants to be a scientist.
Among the children, a little girl has been paying attention to Thanos. Instigated by the little girl, he took his friends to explore a forbidden cave.
In the cave, Thanos didn't fall down or stay with his friends. He kept climbing out, always caring for small animals and thinking of his friends, and climbed for three days. However, when he climbed out of the hole, he found that his friend had been eaten by a small animal that he thought was cute. Because of this, the monster in Thanos's heart has begun to awaken. Encouraged by the girl, he killed the animals in the cave crazily and vented his emotions. In the blink of an eye, many years have passed, and Thanos is the best child in Titan's history (see, he didn't learn to bully, but he still wants to conquer the universe? )
However, in his spare time, Thanos has an unknown secret "career".
He invented a set of dissection tools by imagination, dissecting creatures cruelly, hoping to find the answer to the question in this way: Why am I born different? However, Thanos always got nothing. At the instigation of the girl, he finally began to attack his own people and achieve his own science.
After killing two people, because no one knew about the killing on Titan, everyone thought that the two people who were killed were just damaged by the spaceship and lost in the universe.
Thanos felt that he had gone too far. What he had done was beyond the scope of the experiment. He wants to stop the experiment.
However, the girl's words made him understand that he killed his people not because of experiments, but because he liked to kill people.
Thanos expressed his love to the girl (suddenly ...), but was slapped by the girl, saying that he was not qualified for Thanos to kill his own people constantly and quietly, and the18th ethnic group he killed was his mother.
After killing his mother, Thanos left Titan and went to a corner of the universe to start a new life. He wanted to forget everything, keep leaving seeds, join the pirates and become a technician, but refused to kill anyone. He wants to forget everything about that girl.
