Before you read
This fanfic is not going to entirely follow the canonical Young Justice to accuracy. Some versions of characters have been shifted in age and swapped with versions from other comic lines which I find to be better written.
Some spoilers about a major change in the future. Instead of the time skip and inclusion of the Outsiders into the story, this story would accommodate the storylines of the Teen Titans animated show. After that, every plotline is going to be mostly original with inspiration from major events in DC comics. The main character John Constantine will have his own overarching story throughout the series.
