No, in the official Naruto and Mortal Kombat canons, Naruto has no relation to Sindel at all. But fanfiction is a place for wild ideas. Maybe the author of that particular fanfiction had a really strange and interesting dream that led to this idea of Naruto being Sindel's grandson. It might be part of a much larger and complex story within the fanfiction that combines the ninja world of Naruto and the dark, fantastical world of Mortal Kombat.
One interesting Sindel fan fiction could be about her early life before all the chaos in the Mortal Kombat universe. It might explore her relationships, her training, and how she became the powerful figure she is known as. Another could be a story where Sindel teams up with unexpected characters from different realms to fight a common enemy, which would bring in a lot of interesting character dynamics.
Character development is crucial. Since they are from different worlds, seeing how they change as they interact with each other is interesting. For example, Sindel might learn about Naruto's sense of loyalty and Naruto could understand Sindel's strength in a different way. Also, the plot often revolves around a common threat or goal that brings them together, like a powerful enemy that threatens both of their worlds.
Well, the canon status of MK comics isn't straightforward. It might be canon within certain story arcs or universes, but not across the board. Different interpretations and continuities can come into play.
The plot could involve Naruto having some special powers inherited from Sindel. Maybe he can use some of her magical abilities along with his ninja skills. For example, he could use Sindel's power of flight in combination with his shadow clone jutsu to create a really unique combat style.
Well, 'A New Chapter for Naruto and Sindel' is another great one. It takes a different approach by having Naruto travel to Sindel's world. There, he has to adapt to the new environment while also trying to find a way back home. Along the way, he and Sindel form an unexpected friendship that drives the story forward.
