In this fanfiction, Julius could be a fallen hero who has lost his way. Ishtar, seeing his potential, decides to take him under her wing. She uses her divine powers to help him regain his strength and purpose. As they train together, a relationship blossoms. However, there are those in the heavens who oppose Ishtar's relationship with a mortal, and they try to separate them, leading to a series of adventures and battles as Julius and Ishtar fight to stay together.
For Julius, his personality can be developed through his actions. If he's initially presented as a bit reckless, his experiences with Ishtar could make him more cautious. For example, if he jumps into battles without thinking, Ishtar could teach him the value of strategy. Ishtar's personality can be developed by showing her different sides. Maybe she's always been seen as a cold and distant goddess, but through her relationship with Julius, she shows her more caring and vulnerable side.
Maybe Ishtar, for some reason, has her powers sealed in the Naruto world. Naruto, being the hero he is, gets involved in helping her regain her powers. Along the way, they have to face off against enemies who also want to use Ishtar's power for their own evil purposes. As they work together, a bond forms between them, changing both of their outlooks on life.
One idea could be that the heroes from Dragon Ball Heroes face off against an unexpected villain from the world of x note in a tournament setting. The battles could involve unique power-ups and strategies.
One idea could be exploring an alternate universe where Naruto's parents didn't die. This would change his whole upbringing and how he views the world. He might not be as driven to become Hokage in the same way, and his relationships with characters like Iruka and Sasuke could be very different.
Perhaps there's a situation where the heroes of tomorrow are suddenly stripped of their powers. They then have to rely on their wits, training, and teamwork more than ever. They find out that an old enemy from the original Avengers' past has developed a technology that can nullify superpowers. Now they have to figure out how to get their powers back and stop this enemy before it's too late.
A great plot idea could be a time - travel plot. What if one of the heroes accidentally travels back in time to before they got their powers? They could try to prevent a certain event that led to the creation of a super - villain. Or, perhaps a hero gets sent into a parallel universe where the roles are reversed and the villains are the heroes. This would force them to reevaluate their own beliefs and actions.
One idea could be a crossover with the Naruto universe. The Saiyans could learn about chakra and how to use it, while the ninjas are amazed by the power of ki. Another could be a time - traveling plot where the Dragon Ball Heroes characters end up in the past of their own world and have to prevent a major catastrophe that changes the course of their history. Maybe a crossover with One Piece where they search for the One Piece together and face off against the powerful pirates and the Marines.
Perhaps the heroes assemble to save a powerful magical artifact that is being targeted by a group of dark forces. Each character could bring their own knowledge and abilities to the quest. For example, Hermione's vast knowledge of spells and potions would be crucial, while Harry's courage and experience in facing dark wizards would lead the group. They might also encounter new magical creatures along the way that they have to either befriend or fight.
One idea could be that the heroes travel back in time to the founding of Camp Half - Blood and have to deal with the very first demigods. They might face challenges like different rules and more primitive living conditions. Another could be going back to a time when the gods were at war with each other more openly and getting caught in the middle of it. Maybe they travel forward in time and see a future where the demigod world has completely changed, like new alliances between different pantheons.
Well, you could write a fanfiction where the Next Avengers: Heroes of Tomorrow have to deal with the public's perception of them. They are young and new, and not everyone trusts them. They could struggle with proving themselves worthy of the Avengers name. Maybe there's a media smear campaign against them, and they have to find a way to clear their names and gain the public's trust. This could involve them doing heroic deeds that are initially misinterpreted, and they have to work hard to set the record straight.
