Barbara Gordon could be a main character. She has connections to the Batfamily in multiple ways, and in the context of 'the art of love', her relationships, whether it's her friendship with Dick or her mentorship - like relationship with others, can be explored. Also, Damian Wayne is bound to be there. His growth within the family and his evolving understanding of love, especially considering his unique upbringing, would be interesting to see in this fanfiction.
Obviously, Batman and his family like Robin, Batgirl would be main characters from the Batfamily side. And from the Justice League, Superman, Wonder Woman, Flash etc. would be the main characters. They are the most well - known members of their respective groups.
One key theme could be the complex relationships within the Batfamily. In fanfiction, the 'art of love' might explore the different forms of love like brotherly love between Dick and Damian, or Batman's paternal love for his proteges. Another theme could be sacrifice, as love often leads characters to make sacrifices for one another in the Batfamily's world.
Naruto himself is very likely to be featured. He's the main character after all.
Naruto is a very likely character. Given his rebellious nature and his history of being an outcast in some ways, it's easy to imagine a scenario where he gets caught up in something that lands him in prison. His determination to break free and his loyalty to his friends would make for an interesting story.
Finn and Jake are bound to be main features. They've been at the heart of the series all along.
The main characters in the 'Spider Man Complete Story' would be Spider - Man (Peter Parker) without a doubt. His enemies are also important characters in the story. Venom is one of the most iconic villains and is likely to be in it. And then there are the supporting characters like J. Jonah Jameson, the editor - in - chief of the Daily Bugle. He often causes trouble for Peter Parker. Also, Gwen Stacy, another love interest of Peter's, is likely to be part of this complete story.
Sasuke would likely be featured. Since he and Naruto have a deep bond, Sasuke might be involved in Naruto's decision to retire or in filling the void left by him. Also, Naruto's family, like Hinata and his kids, would be important characters. They would be part of Naruto's post - retirement life, showing how they support him or how they are affected by his new lifestyle.
Well, for sure Yugi would be in it. He has that special bond with the spirit of the Millennium Puzzle, and that could lead to all sorts of adventures in the world of The Ocarina of Time. Then there's Joey. His loyalty to Yugi and his own dueling skills could play a role. In terms of The Ocarina of Time characters, Zelda would likely be involved. She has her own powers and knowledge, and her interaction with the Yu - Gi - Oh! characters, especially Yugi, could be really interesting. And of course, Ganon could be a major antagonist in the fanfiction, causing trouble for both sets of characters.
There could also be appearances from other characters like Smackle. Maybe she's initially uncomfortable with the idea of wearing a bikini but through her friends' support, she gains confidence and has a great time at a pool party or beach outing in the fanfiction.
Obviously, Harry Potter himself would be a central character. He's the main protagonist in the series, so it's likely he'd be involved in the Christmas - related events. Hermione Granger would also be there as she's Harry's best friend and loves to participate in all things magical and festive. Ron Weasley too, as he's part of the trio. Dumbledore might also make an appearance, perhaps guiding the students in some Christmas - themed activities or sharing some wise words about the season.
