Another theme is redemption. Some fanfictions focus on a character from either team who has made mistakes in the past.

It has some really interesting plot twists and character interactions that make it a great read for fans of the series.
One common theme is friendship. Since the Lupinrangers and Patrangers are two different teams, OC fanfics often explore how new characters can bridge the gap between them and form strong friendships. Another theme is rivalry. The original show has elements of rivalry, and in OC fanfics, new characters might add more depth to this dynamic. And of course, there's the theme of justice. New OCs might have their own ideas of justice and how to achieve it within the world of Lupinranger vs Patranger.
