I think Beast Boy would be a likely candidate. He has an open - minded and friendly nature. He's used to dealing with different and strange beings because of his own abilities and the various adventures he's been on. So, he might be the first to approach Danny's clone and try to befriend it.
Robin might be the one to befriend Danny's clone. He's intelligent and curious. He would see the potential in the clone, whether it's a source of information or an ally. Robin would be interested in understanding how the clone was created and what it can do. And through that process of investigation, he could form a bond with the clone.
I think Superman would be the most likely. Superman is known for his kind heart and open - mindedness. He would probably see Danny as a young hero in need of some guidance and friendship. He wouldn't be too quick to judge Danny based on his ghostly appearance or powers.
In such a fanfiction, there could be a lot of chaos. Maybe Danny's clone has powers that the Young Justice team doesn't understand at first. They might initially see the clone as a threat and try to contain it. However, as the story progresses, they could discover that the clone is more complex and has its own consciousness, leading to a situation where they have to decide whether to help the clone or destroy it.
The Flash clone in the fanfiction might have a different origin story compared to the original Flash. It could be the result of a scientific experiment gone wrong or a plot by a villain. This would add an element of mystery to the story.
In fanfiction, the Wonder Woman clone could be a symbol of hope or a dark omen depending on how she is written. If she is written to be a force for good, she could inspire the Young Justice team to new heights. But if she is written as a corrupted version, she could represent the potential for evil within the heroes themselves, as they see a distorted reflection of Wonder Woman in her.
The concept of a Wonder Woman clone in Young Justice fanfiction can also be used to explore the idea of nature vs. nurture. Is she destined to be like Wonder Woman just because of her genetic makeup? Or will her experiences in the Young Justice world shape her into something completely different? Writers can play with this idea, showing her development as she interacts with the other characters and faces different challenges.
One possible idea for a 'Young Justice Red X Clone' fanfiction could be that the clone has to struggle with identity issues. It's constantly compared to the original Red X and has to find its own place in the world. Maybe it starts out as a weapon created by an enemy but then begins to develop its own sense of self.
Obviously, Danny Phantom is one of the main characters as the title implies he's the one doing the pranking. And then, members of the Justice League like Superman, Batman, Wonder Woman, Flash, etc. would be the ones being pranked.
Danny Phantom is for sure the main character on the saving side. On the Justice League side, all the classic members would probably be there. Superman, being the symbol of hope and having super strength, heat vision etc. Batman, the Dark Knight with his gadgets and detective skills. Wonder Woman with her Lasso of Truth and superhuman strength. The Flash, who can move at incredible speeds. Green Lantern, who can create constructs with his power ring. And Martian Manhunter, with his shape - shifting and telepathic abilities. They all could be in danger and Danny would have to figure out how to save each of them based on their unique powers and vulnerabilities.
The plot could revolve around a threat that only the Flash clone can stop. This would give the clone a chance to shine and prove its worth. It could also lead to a team - up with other Young Justice characters, like Robin or Aqualad. They might initially be skeptical of the clone but then come to rely on it as the story progresses.
One great 'Young Justice Danny Phantom' fanfic is 'Phantom in Gotham'. It has an interesting plot where Danny's ghostly abilities interact with the Young Justice team in Gotham city. Another is 'Danny's New Allies' which focuses on how Danny teams up with the members of Young Justice and the dynamics between them.
