I'm not entirely sure as I haven't read this specific fanfiction. It could be about a disrupted or alternative version of a story where Danny Phantom interacts with the Justice League in some unexpected or 'broken' way.
Well, 'broken' might imply that the normal rules or storylines within the Danny Phantom and Justice League universes are somehow fractured. Maybe it's a fanfic where the characters' powers work differently, or their relationships are all jumbled up. For example, Danny Phantom's ghostly abilities could have some glitches when he's in the presence of the Justice League members, leading to all sorts of strange and unforeseen situations.
I think it could be Superman. Superman is all about truth and justice and he would likely see the good in Danny. Also, they both have super strength in a way. Danny has his ghostly strength and Superman has his Kryptonian strength. They could bond over protecting the innocent.
One common theme is the clash of two different worlds. Danny comes from a world where ghosts are a big part of his life, and the Justice League is from a more traditional superhero world. So there's often a theme of how they deal with each other's differences.
I'm not familiar enough with 'broken danny phantom justice league fanfiction' to give exact similar ones. However, you might explore fanfics that focus on alternate universes for both Danny Phantom and the Justice League. Fanfics that play with the characters' moral alignments or change their origin stories could potentially be in a similar vein. Check out some of the more experimental crossovers on popular fanfiction platforms.
Well, in such a fanfiction, the story might start with some sort of misunderstanding. Perhaps the Justice League mistakes Danny for a threat. Danny, being a hero in his own right, would not back down. He might first try to reason with them. But if that fails, he'd engage in a battle. His ability to turn invisible could make it really difficult for the League to track him, especially for heroes like Wonder Woman who rely on their eyesight in combat.
Danny could use his ghostly powers to disrupt the technology that some Justice League members rely on. For example, he could mess with Cyborg's systems. His ability to overshadow people might also be a key factor, allowing him to control some of the less - powerful members.
Another storyline might involve Danny being wrongly accused by the Justice League of a crime he didn't commit. As he tries to prove his innocence, he uncovers a deeper conspiracy that threatens both the human world and the Ghost Zone. He has to use his wits and powers to clear his name and save the day.
In this fanfiction, perhaps Danny Phantom discovers a plot against the Justice League early on. He then uses his invisibility and intangibility to gather information. His ability to fly and super strength (in his ghost form) would be crucial in battles against the villains targeting the League. For example, if the villains had some sort of kryptonite - like weapon against Superman, Danny could use his powers to either disable the weapon or protect Superman until they find a way to neutralize it.
One possible plot could be that Danny Phantom is facing a threat in his own dimension that is beyond his control. He decides to call the Justice League for help. Maybe he first has to figure out a way to contact them across dimensions. Once he does, the Justice League initially doubts his claims but as they start to investigate, they realize the severity of the situation and they all work together to fight the new and strange enemies from Danny's world.
In such a crossover, Danny could team up with Superman. Danny's ghost powers would be really interesting combined with Superman's super strength. Maybe they'd fight a common enemy that has powers related to both the supernatural and advanced technology.
Well, he could bring his unique ghost powers to the team. His intangibility and invisibility would be great for stealth missions. And his ghost ray could be a powerful offensive weapon. Maybe he'd also have some funny interactions with the more serious Justice League members like Batman.
