Joey could be an ordinary citizen who just happens to be in the wrong (or right) place at the wrong (or right) time and meets the Batfam. Maybe he's a journalist trying to get a scoop on the Batfam and ends up getting more than he bargained for.
One popular plotline is the rivalry intensifying. Joey is always looking to prove he can beat Kaiba at his own game, so there are often duels where the stakes are high and the tension is palpable. Another plotline could be an unexpected alliance. Maybe there's a new and powerful enemy in the dueling world, and they have to put aside their differences to defeat it. And sometimes, there are fanfictions where Joey discovers a softer side to Kaiba, which changes their dynamic in an interesting way.
