I remember a fanfic that focuses on Madara's past and how he obtained the Rinnegan. It's really detailed and gives a whole new backstory to his character. It also shows how his Rinnegan powers evolved over time. This fanfic has great character development for Madara and also includes some interesting side characters that interact with him in different ways related to his Rinnegan abilities.
A good Naruto Rinnegan Madara fanfic should first of all stay true to the character. Madara is a powerful and complex character, and his Rinnegan abilities should be portrayed accurately. For example, his ability to control the tailed beasts using the Rinnegan should be shown in a way that makes sense within the Naruto universe.
One interesting fanfic could be 'Naruto: The Dual - Eyed Avenger'. In this fic, Naruto's acquisition of the Rinnegan and Sharingan completely changes the power dynamics in the Naruto universe. His new abilities make him a force to be reckoned with, and he uses them to protect Konoha in ways no one expected.
One great 'Mata Rinnegan Naruto Fanfic' is 'The Rinnegan's Ascent'. It really delves into how Naruto might interact with the power of the Rinnegan in new and unexpected ways. The author does a wonderful job of exploring the lore and creating unique battles and character development.
In some fanfictions, it could be through a strange and powerful jutsu transfer. Maybe Madara, on the verge of defeat, decides to transfer his Rinnegan power to Naruto for some unforeseen reason, like seeing a new path for the ninja world in Naruto.
Naruto would probably win. He has an indomitable will and has always found ways to overcome powerful foes. His experience and the unique powers he might gain with the Rinnegan could give him an edge over Madara.

One great 'Female Naruto x Madara' fanfic is 'The Unlikely Bond'.

He could combine the Rinnegan's ability to control gravity with his Rasengan, creating a super - powerful and hard - to - dodge attack.
There's a fanfic titled 'Power Convergence'. It features a story where a character with the Rinnegan somehow ends up in the Fairy Tail world. The author does a great job of exploring how the Rinnegan abilities would be perceived in a world full of magic. It has some epic battles between the new 'hybrid' character and the powerful mages of Fairy Tail.
