Izuku Yagi: The Fourth Halfa

Most people now believe the first heroes came after quirks, but that couldn't be further from the truth. In reality, the first hero came long before the first quirk was found, almost 200 years before in a little town called Amity Park. The fourteen-year-old half-ghost hero Danny Phantom, real name Danny Fenton, was the only hero that existed at that time. He, nearly single handedly, protected his town from the beings known as ghosts until he defeated The Ghost King and gained the title Prince Phantom, hear to the throne of the Infinite Realms. At first he rejected the title, wanting to live his life on earth but circumstances proved that to be impossible when a young Danielle Phantom came into the picture. A clone created by Danny's arch nemisis Vlad Plasmius. After she left and came back almost destabilizing due to her unstable nature Danny decided he didn't want to loose her and claimed her as his daughter. When he tried to tell his ghost hunting parents about this they rejected him, calling him a freak and a monster. Danny's friends and sister tried to defend him but it was all for naught as his parents refused to see reason. With no choices left Danny fled to the Ghost Zone with Danielle, his friends and sister following him, then shut off the Fenton Portal perminantly. Soon after he took the mantle of Ghost King and when his friends and sister died they became his ghostly advisors while Sam Manson became his queen and the mother of Danielle. Many years later Clockwork, the ghost of time, would tell Danny that another portal was being made. He knew he wouldn't be able to fight off the ghosts himself as he had his duties as king and none of his friends would be able to do it as they had their own duties. Knowing this Clockwork came up with an idea, the creation of a new Halfa. And thus, Izuku Yagi's alter ego as Specter: The Ghost Hero was born.
