One great Naruto Shadow Clone fanfic is 'The Shadow Clone's Adventure'. In this fic, the shadow clones develop their own personalities and go on unique quests while Naruto is training. It offers a fresh perspective on the use of shadow clones.
Another interesting one is 'Among the Shadow Clones'. Here, the story delves deep into the bond between Naruto and his shadow clones. It shows how they communicate on a deeper level and how they can work together in ways that Naruto himself hadn't even considered before, which makes for a very engaging read.
There's also 'Shadow Clone Revolution'. This fanfic focuses on how Naruto's overuse of shadow clones in a different way than in the original series leads to a new set of challenges and relationships within the Hidden Leaf Village. It's really interesting to see how the story unfolds as the clones start to have more autonomy.
