What are some interesting plot ideas for an 'anti hero justice league fanfic'?

For a Naruto anti - hero in the Justice League fanfiction, he could be a character who is on a quest for redemption. In the Naruto world, he may have done some things that he regrets. In the Justice League, he sees an opportunity to use his powers for good in a different way. He might have the ability to summon some of the Naruto creatures, like toads, and use them in battles against the League's enemies. His costume could be a mix of Naruto - style clothing and elements from the Justice League uniforms.

One idea could be a story where Batman has to lead the Justice League in a fight against a powerful new villain who can manipulate time. This would put Batman's strategic skills to the ultimate test as he tries to coordinate the different powers of the League members. Another plot could be that a member of the Justice League is secretly under mind control and Batman has to figure out who it is before they cause too much damage.

One idea could be an OC with the power to manipulate time joining the Justice League. They could accidentally create a time rift during a battle, and the League has to fix it while also dealing with the OC's insecurities about their powers.

Deadshot would be a great main character. He's a skilled assassin with his own code of ethics that often puts him at odds with traditional heroes. His sharpshooting skills and complex personality would add a lot of depth to the story.

Perhaps Trunks is initially mistaken for a threat by the Justice League. But as they learn more about him and his mission to protect his own timeline, they start to work together.

Meanwhile, Wonder Woman could teach Trunks about the different cultures and values in the Justice League's world.
