His character would develop in terms of his relationships. His friends would be both amazed and a bit envious of his new powers. He'd have to deal with that. And he might also form new friendships with those who are interested in the supernatural aspect of his powers. Izuku would also become more responsible as he has to keep his powers a secret from the wrong people. He'd learn when to use them and when to rely on his normal skills.
Izuku would likely become more confident. With Danny's powers, he'd have an edge in battles. He might start to stand up to bullies like Bakugo more quickly. His self - esteem would grow as he realizes he can be a great hero not just with a quirk, but with these unique powers.
Living with Wonder Woman could expose Danny to different sources of power. Themyscira might have some sort of energy or magic that could interact with his ghostly powers. This could lead to the development of new powers or a different form of his existing powers. For example, he could gain the ability to fly faster or have a more stealthy form of phasing that is not only useful for going through physical objects but also for sneaking around undetected in a more magical or energy - based sense. His powers would no longer be just about being a half - ghost, but a combination of his ghostly nature and the new elements he's exposed to through Wonder Woman and her world.
His powers could become more ice - based. Instead of the normal greenish - blue energy, his blasts might turn a frosty white. His ability to fly could also be affected, with a cold trail following him as he moves through the air.
Danny would likely become more empathetic. Usually, he sees Desiree as a bit of a nuisance when she's causing chaos with her wishes. But in a story where he frees her, he has to understand her situation more deeply. This would make him more in tune with the feelings of other ghosts, not just seeing them as adversaries.
Danny might become more self - centered. Since Desiree is often motivated by her own desires, Danny could pick up on some of those traits. He may start to use his powers more for personal gain rather than for helping others as he usually does.
His confidence might grow. Flash is a well - known and respected hero, so being around him could make Danny believe more in his own abilities. He may become more outgoing and less hesitant in using his powers for good.
His powers would likely be used more for malevolent purposes. Instead of using his intangibility to avoid danger and protect others, he might use it to sneak up on people and startle or harm them.
The Joker would probably be both intrigued and excited. He might see Danny's powers as a new and interesting toy to play with. He could try to find ways to manipulate Danny into using his powers for the Joker's own chaotic purposes. For example, he might trick Danny into using his intangibility to break into a high - security building so the Joker can plant some crazy bombs or something.
In the lead - up to the wedding, they would have to work through a lot of issues together. Sam might help Danny come to terms with his role as a half - ghost in a more positive way. And Danny would support Sam in dealing with her family's concerns. This would strengthen their bond and make their relationship more mature and stable for the wedding and beyond.
The fanfiction could center around Izuku being the only one who can see and fight a new type of ghost - like villains. Since he has Danny Phantom's powers, he's the only hope. He has to learn how to balance his normal hero training with mastering these new powers. Maybe he discovers that there's a connection between the origin of Danny's powers and the world of quirks, and this knowledge helps him become an even more powerful hero, saving both the physical and spiritual realms.
Naruto's character would likely become more carefree. Luffy's powers often come with a sense of fun and adventure, and Naruto might adopt some of that. He'd be more likely to take risks and approach situations with a more light - hearted attitude.
