Technically I only made this for myself so I can keep track of how much material I've incorporated from the Cartoon Network Universe. But since it's gotten so big, I thought I'd just throw it into the story as the index or glossary. Feel free to use it for whatever purpose while reading the story. Maybe you don't know who someone was because you never watched their show or maybe you don't know who I'm referring to when I use an alternative name. Feel free to suggest improvements to it as well such as more in-depth descriptions, altered canon, types of material like shows or monster names, etc.
This will be updated as new material or more information about a certain character is added to the story's universe (and this includes other stories within my fanon such as FusionFall: Recollection).
