A great plot for 'ocarina of time crossover fanfiction' could be a crossover with the Final Fantasy series. Link could meet characters like Cloud or Squall.

Or perhaps a crossover with the Pokémon world. Link could befriend Pokémon and use them in his quests, while also teaching the Pokémon trainers about the ways of Hyrule.
For 'ocarina of time crossover fanfiction', a crossover with the Harry Potter universe would be exciting. Link could enter Hogwarts and interact with the students and professors.

He then has to navigate this new world, using his ninja skills and making new friends and allies there.

They were important in the game, and these fanfictions expand on their influence, like how they might be involved in protecting ancient secrets that could change the future of Hyrule.

One idea could be that Elsa's powers somehow link to a magic in the Once Upon a Time world. Maybe her ice powers are the key to unfreezing a character who has been trapped by a dark curse.
