One interesting plot could be about a common enemy that forces Naruto, the Justice League and the Teen Titans to team up. They have to overcome their differences in fighting styles and values to defeat this powerful foe. Another plot might be a competition between the three groups to see who can solve a mystery or complete a mission first, which would lead to a lot of rivalries and interesting interactions.
In a Naruto x Justice League vs Teen Titans fanfiction battle, Naruto could potentially hold his own against the Justice League. His shadow clone jutsu could confuse Superman for a moment, and his rasengan might be able to do some damage. But the Justice League has Batman's strategic mind. The Teen Titans, on the other hand, have Raven's magic and Beast Boy's shape - shifting. It would be a chaotic and exciting battle where the outcome would be determined by who uses their abilities more effectively at the right time.
Well, the 'Teen Titans Go' origin story starts with these diverse characters. Robin, for instance, brought his skills learned from the Dark Knight. Starfire came from another planet with her own set of abilities like flight and energy blasts. Beast Boy, who was experimented on, can turn into any animal. Cyborg was created after an accident that fused him with technology. Raven, with her demonic heritage, has strong magic. They joined forces as Teen Titans, facing challenges like the Brotherhood of Evil and other baddies in their city.
There are many great fanfictions about Robin and Starfire in Teen Titans Go. Some might focus on their first date, perhaps in a really cute scenario where Robin tries to plan the perfect evening for Starfire. He could take her to a special place in Jump City that has meaning for both of them, like the place where they first met as heroes.
Batman's origin in Teen Titans Go is somewhat of a comical take on the traditional origin. He witnessed the death of his parents in Crime Alley which drove him to fight crime. But in the Teen Titans Go version, it's presented with their signature humor.
One common theme is acceptance. The fanfics often deal with how the other characters accept the gay relationship within the Titans group. It shows the importance of friendship and support in such situations.
A cool Teen Titans Go fanfiction idea could be centered around a holiday. For example, during Christmas, a villain tries to steal all the presents in Jump City. The Teen Titans have to not only stop the villain but also make sure the city still has a great Christmas. Another idea is a fanfiction where Raven gets amnesia. The other Titans have to help her regain her memories while also protecting her from those who might take advantage of her in this vulnerable state. And then there could be a fanfiction where Beast Boy discovers a new animal form that he can't control at first, and the Titans have to help him master it.
It's really hard to say. The Young Justice has some really powerful members like Superboy and Miss Martian. But the Titans also have strong characters like Starfire and Cyborg. It could depend on the situation. If it was a battle in an open field, the Titans' more experienced members might have an edge. But if it was a stealth mission - type battle, Young Justice's skills could give them the victory.
Another theme is teamwork. They have to work together to face various challenges, so the fanfic shows how they combine their different skills and powers. For instance, Cyborg's technological expertise with the Young Justice's strategic planning skills.
