A great idea for a Fairy Tail OC Crossover Fanfiction is to cross your OC with characters from the world of One Piece.

Your OC could end up in Soul Society and learn about the different forms of spiritual power there while also showing off their Fairy Tail magic. Maybe they could even form a team with some of the Soul Reapers to fight a common enemy.
