As of July 2023, I can't recall exactly what role Charles Melton had in 'American Horror Story'. It could have been a complex character with a dark backstory, which is typical for the show. 'American Horror Story' is known for its ensemble casts and twisted plotlines. He might have been part of a sub - plot that added to the overall horror and intrigue of the season. Maybe he was involved in a supernatural or psychological horror aspect of the story. Without more information about the specific season, it's hard to say for sure.
I'm not sure specifically who 'Marliss Melton' is within the context of Fantastic Fiction. It could be an author, a character, or someone related to the Fantastic Fiction world in a particular way. There might be limited information available without further research.
I don't have information on any specific works associated with Marliss Melton in Fantastic Fiction. There could be novels, short stories or other forms of writing that she has contributed to the genre.
Overall, Gotham has some similarities to the comics, but it also makes significant changes to characters and plotlines to make it more unique for the TV series. For example, some characters' personalities and backstories are altered.
