Kai was a psychopath, deemed clinically insane by the medical community. He had always been strange, the kind of strange that would make him dance in a dark room with headphones on while chugging down bottles of milk. Yes, he was a milk addict, and he took it to a whole new level. The voice in his head was his only friend, the only constant in his otherwise chaotic life. One day, Kai escaped from the mental asylum where he had been confined for years. He had no idea what he would do next or where he would go, but he was determined to escape his reality. He found an abandoned building and made it his home, but fate had other plans for him. Kai died in that building, but instead of his consciousness fading away, he transmigrated into the body of a young Thanos. When he realized where he was, he had an existential crisis. Thanos was a madman who pursued the concept of death, but Kai was scared of death. It was ironic that he had transmigrated into Thanos' body.
