One possible plot could be She - Hulk joining the Justice League on a mission to stop a powerful alien threat. She - Hulk's strength and legal expertise could come in handy.

A plot could revolve around a conflict within the Justice League where She - Hulk has to mediate. Maybe there's a disagreement between Superman and Batman on how to handle a new villain.

One possible plot could be that the Hulk is somehow transported to the DC universe and is initially seen as a threat by the Justice League.

The Hulk's brute strength combined with the Justice League's diverse powers could make for an epic battle against this enemy.
She - Hulk's legal background would add an interesting dimension. The Justice League often deals with complex situations that could involve legal aspects. She could help them navigate through any legal loopholes or treaties. For example, if they have to deal with an international incident caused by a supervillain, she could be the one to sort out the legal implications.
Definitely Superman. He has the strength and the moral compass to try and understand the Hulk. He can also withstand the Hulk's attacks to a certain extent, so he could be the first to approach the Hulk and attempt to form an alliance. He might see the good in the Hulk, similar to how he sees the potential for good in Lex Luthor at times.
Maybe in the fanfiction, the Hulk's gamma radiation has an unexpected effect on some of the Justice League members. For example, it could give Superman a new vulnerability or temporarily enhance the powers of Flash in a strange way. This leads to a complex situation where they need to both deal with the Hulk and the consequences of this new development.
In this fanfiction, Robin could be saving the Justice League from a threat that they didn't see coming. For example, a mind - controlling parasite that has infected some of the members.

Well, it could be about Batman initially being hesitant to fully join the Justice League. Maybe he has trust issues with some of the members at first. Then, he gradually starts to work with them on a big threat that requires all their skills combined, like an alien invasion or a powerful super - villain that's too much for any one hero to handle alone.
The plot could start with Vegeta being exiled from his own planet due to some political intrigue. He ends up on Earth, where he crosses paths with the Justice League.

They might have to split up, with some members protecting Batman and others going after the bad guy.
