Anime meets JLA unlimited

[Seed00]

This is a crossover with Justice League unlimited where various characters are sent to the JLA universe.

The list is:
Ichigo
Naruto
Harry Potter
Gambit

Ichigo is sent right after hi sfather divulges he's a shinigami. Ichigo doesn't take it well.

Naruto is hokage but he's still not liked or respected. Turns out Kyuubi was lying when he said he was the strongest of the bijuu. Naruto seals a twelve tailed tiger in his stomach along with Kyuubi. Gets along well with Etrigan.

Forgot how Harry got there.

Gambit was sent there as well. He was more familliar with dimension jumping so he's not so surprised. This causes headaches for Superman and Batman.

I favorited in my lists but I have so many stuff favorited that I can't remember.

Those were major clues to said story. Can anyone help me out?
