Well, 'Meet the Phantoms' in Danny Phantom fanfiction could be a really exciting concept. It might center around the idea of Danny, who is already half - ghost, getting to know more about the phantom world. It could explore different aspects of the phantoms' culture, if they have one. There could be some sort of gathering or event where all kinds of phantoms come together, and Danny and his pals are there to witness or participate in it.
Obviously, the main character would be Danny Phantom himself, but in two different forms or versions.

Another possibility is that he's facing some emotional turmoil. Danny has a lot on his plate. He has to keep his identity a secret from his friends and family, deal with school, and fight ghosts.
