A common theme is the clash of different powers. Naruto has his chakra - based ninjutsu and Skarlet has her own unique powers. Fanfictions often explore how these powers interact when the two characters meet.
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.
One popular Naruto and Skarlet fanfiction is 'The Unlikely Alliance'. It's a story that brings together Naruto's world of ninjas and Skarlet's unique abilities in an interesting way. The characters are well - written and their interactions are engaging.
There could also be a story of redemption. Suppose Skarlet has done some bad things in the past, and Ermac, being a more morally upright character, decides to help her redeem herself. They go through a series of trials together, and through their friendship and mutual understanding, Skarlet slowly changes for the better, becoming a more positive force in the Mortal Kombat world.
A fanfic like this might focus on their individual powers and how they complement each other. Ermac with his telekinetic abilities and Skarlet with her blood - based powers could team up in unique ways. For example, Ermac could use his powers to control the blood that Skarlet manipulates, creating a powerful combination. The story could revolve around them training together to master these combined abilities and become an even greater force in Mortal Kombat.
The length of the MK9 story varies depending on how quickly you progress and explore all the elements. But on average, it can take several hours to complete the main storyline.
