Phoenix Wright is often a popular character as he is the main protagonist in the Ace Attorney series.

One interesting ace attorney neko fanfiction could be one where the main characters are transformed into nekos and have to solve cases in this new form. It adds a fun and unique twist to the usual courtroom drama.
One interesting crossover could be in a courtroom setting. Imagine Phoenix Wright from Ace Attorney defending Batman in a Gotham court. Batman's rogues' gallery could be witnesses, and Phoenix would have to use his legal skills to prove Batman's actions were just. Another crossover could involve the investigation aspect. Batman's detective skills combined with the Ace Attorney's unique way of uncovering evidence would make for an exciting story.

Well, a great Ace Attorney crossover fanfiction idea is to cross it with "Fullmetal Alchemist". Edward and Alphonse could be involved in a case where alchemy is misused and Phoenix Wright has to use his legal skills to uncover the truth. Also, a crossover with "My Hero Academia" would be cool. Heroes being accused of crimes they didn't commit and the Ace Attorney characters having to defend them in a world full of quirks.

You could also write a fanfiction based on an alternate universe. For example, what if the characters were in a steampunk world? The courtroom scenes would be really unique with steam - powered gadgets and different social norms.
