When Superman Disappears

That day, Superman disappeared... AD 2016. In the world where I traveled, the Mayan prediction of the end of the world was verified. It's an invasion by an alien civilization called "Weirdos". They have strange shapes: some are slimes covered in tentacles, some are goblins in groups, and even vampires specialize in drinking the blood of young girls. But there is good news. A man who calls himself Superman has protected the entire earth by himself, and can destroy the top monsters with one punch. The alliance formed by the remaining top combat power of the weirdos had to take the initiative to sign a peace agreement with humans. Human beings are proud of him, praising his handsomeness and praising his strength, but no one knows where he comes from. This went on for ten years. After an ordinary afternoon, no one saw Superman again. At first, people just thought he was going on vacation, until he was attacked again by monsters, and mankind was completely defeated. Most of the human beings who lost their protection put aside their blood and dignity and raised their flags to surrender. But there are still a few people who rely on serum made from the blood left by Superman, awaken their superpowers through injections, and build protective zones to survive. And I awakened to [Indiscriminate Imitation], which allows me to imitate other people's superpowers based on their DNA. But the talent is the lowest "E" level, but it's better than nothing. It happened that the school was conducting research to obtain the remaining DNA in the blood left by Superman. When the werewolf bared its teeth and claws, the crowd once again faced a desperate situation, and it was a time of despair. That day, the new Superman appeared...
