Another theme is the development of trust. At first, they might be wary of each other. But as the story progresses, they start to trust one another. This is often shown through them relying on each other in dangerous situations. For instance, in a battle scenario where Percy uses his powers to protect Natasha and vice versa, which deepens their bond of trust.
There's also 'Percy and Natasha: A New Alliance'. In this fanfic, their different backgrounds lead to some really interesting interactions. It delves deep into how they come to understand and respect each other over time. The author does a wonderful job of building their relationship in a believable way.
She would likely become angry. Natasha is a strong character, and being betrayed would stir up her fury. She might start planning her revenge, using her skills and intelligence to get back at Percy. Maybe she'll try to expose his true motives to others in their world or group.
The character dynamics. Percy is often portrayed as brave, a bit reckless at times, but with a strong sense of loyalty. Natasha is a complex character, a highly skilled spy with a troubled past. Their interactions can range from initial mistrust to a deep friendship or more, depending on the story. For example, Percy's powers can be used in creative ways to help Natasha in her missions, and Natasha's skills can protect Percy in a world he doesn't fully understand.
Another idea is that Percy gets thrown into the Marvel universe and Natasha is the first one to find him. She initially thinks he's some kind of new super - powered threat but soon realizes he's from a different realm. They then have to figure out how to get Percy back home while also dealing with the various threats that are attracted to Percy's presence in the Marvel universe.
One aspect of Natasha x Wanda fanfiction could be the exploration of their unique relationship dynamics. In many fanfictions, their different personalities - Natasha's stoicism and Wanda's more emotional nature - are contrasted and combined in interesting ways. This can lead to stories full of tension and mutual understanding.
One popular 'Percy Jackson x Natasha Romanoff fanfiction' is 'Cross - Realms Encounter'. It weaves an interesting story of how Percy and Natasha meet across different fictional universes and team up for various adventures. The character interactions are well - written, with Percy's demigod powers and Natasha's spy skills creating a unique dynamic.
Since 'lemon' implies adult - themed content, one common theme might be a romantic or sexual relationship between Percy and Natasha. However, this goes against the original nature of many of the source materials they come from. Another could be the exploration of their characters in a more intimate setting, but again, this is not in line with the typical portrayal of these characters in official works.
I'm not aware of any particularly popular mute Percy and Natasha fanfiction off the top of my head. It's a rather specific concept, so it might not have a large number of well - known stories.
A common theme is the power of their friendship evolving into something more. Their powers, which are both formidable in different ways, can also be a factor that draws them together. They might train together and during these sessions, feelings start to develop.
