Your personal Sin
Moon wakes up in his own body and is in a coliseum. He looks out to the crowd and sees people that look human but feel different. They feel more like Astro. Moon looks at some people in the coliseum and sees some people from history books. These people feel like him but are different. Moon closes his eyes and senses that everyone there is stronger than him and better than him and every way. This feeling makes him feel a hint of strong fear. Then he opens his eyes and looks forward at two people fighting. This fight makes Moon shake from the pressure.
He keeps looking at the fight and sees that these people are on a different level. This fight is so fast that he can only see some moments of the fight. After a little bit later a sound is heard. This causes the two people who were fighting to stop. Then a voice from the crowd says "The next fight will be happening now!" Strange words from the crowd are heard and Moon is teleported in the spot the two people were fighting earlier. Moon looks forward and is met with a man who is tall, muscular, and has no shirt on. This man has brown long hair and golden eyes. Some person says "This fight is between Astro's pet Moon Crow vs Hercules!"
Moon breaks out into a cold sweat. He thinks to himself "This how I die. There is no way in hell I will be able to leave a scratch on him! Hercules is a famous demi-god who has many fables and isn't forgotten by time." Hercules says "Boy, try with all your might not to make this an understatement!" Moon creates a katana with Naka and rushes him. Moon manages to get close to him then tries to strike him. As soon as the katana makes contact with Hercules it shatters. Moon is shocked by this and Hercules says "Weak!" Hercules punches Moon making him fly into the other people watching. The people he landed into throw him back into the battle. Moon doesn't even have the strength to get back up. Moon's bones were shattered into dust from his punch. Hercules says "You should have died from that punch, yet you lived because your cursed!" The whole crowd starts to speak to each other saying stuff like "Cursed! Why bring a cursed human here? Lady Astro made a disgusting cursed blood her pet? We all know she loves humans but why a cursed one?" Then one person from the crowd said something that Moon would never forget. That person said, "Why don't we execute him!" That action made the whole crowd silent like they got the best idea ever.
The crowd went into a wild fury. These words of hate and pure disgust made Moon pissed no more than that he wanted to shut them up. His bones got fixed in that moment. He stood up and shouted with all his being and said "Shut the hell up!" When he said that he was engulfed in black lightning and he transformed into his demon state. The white parts of his hair turned red. His skin turned crimson red. Lastly, he grew horns and a tail. Moon felt immense pain in his eyes. His eyes went from purple and red to dark red with a hint of yellow. Moon turned into an animal. He went from human posture to an animal on all four.
