One common theme is friendship. They are often shown as comrades in the Mortal Kombat universe, so many fanfictions explore their deep bond of friendship and how they support each other in battles and in the face of challenges.
You can try fanfiction websites like Archive of Our Own (AO3). There are a lot of fanfic writers who contribute their works there. Just search for 'Sub Zero x Smoke' in the search bar, and you'll be presented with a variety of stories.
A plot could involve Sub Zero training Female Smoke in some new combat techniques. During the training, they develop a mutual respect and a deep friendship that might turn into something more romantic as the story progresses. In this fanfiction, their different fighting styles and abilities could create some really exciting action scenes.
Their powers could also be a source of conflict in the story. For example, Sub Zero's cold powers might accidentally harm Female Smoke at first because she is not used to them. Or perhaps there are some situations where Female Smoke's powers interfere with Sub Zero's control over his ice, causing some comical or tense moments in the fanfiction as they learn to work together despite these differences.
One great Sub Zero x Reader fanfiction is 'Frostbound Love'. It has a really interesting plot where the reader character is a healer who stumbles upon an injured Sub Zero. The story beautifully builds their relationship as they face various challenges together. Another one is 'Sub Zero's Secret Admirer' which focuses more on the shy beginnings of their relationship. It's full of cute moments and the way the author describes Sub Zero's character is very accurate.
A good Sub Zero x Reader fanfiction often has a well - developed relationship. It should show how the two characters interact, grow closer, and face challenges together. For example, if there's a story where the reader character helps Sub Zero overcome his inner demons, it makes the relationship more meaningful. Also, accurate portrayal of Sub Zero's personality traits like his stoicism, his loyalty to his clan, and his fighting skills is important.
One common theme is loyalty. Since they are often associated in the original context, fanfictions usually highlight how they are loyal to each other, whether it's in battle or in more personal situations.
One possible plot could be a quest. For example, there's a powerful artifact that has the potential to destroy both of their worlds. Kitana and Sub - Zero are forced to team up to find this artifact before it falls into the wrong hands. Along the way, they face various enemies, including some of their own kind who oppose their alliance. This would create a lot of tension and action in the fanfic.
Survival is also a theme in some 'Sub Zero x Frost' fanfics. They might be in a post - apocalyptic or dangerous situation where they have to rely on each other to survive. This forces them to put aside their differences and work together, which in turn deepens their bond.
One common theme could be redemption. Mileena has done some rather cruel things in the Mortal Kombat lore. Sub - Zero, being a more noble character, could be the catalyst for her redemption. He might see the good in her that others don't and help her change for the better.
