One common theme is the contrast between their personalities. Loki is often mischievous and magical, while Tony is scientific and a bit of a know - it - all. So, there's a lot of fun in seeing how they clash and then come to understand each other.
Another theme is the idea of unexpected friendship. Since they come from such different backgrounds in the Marvel universe, the fanfictions often explore how they can form a bond. For example, baby Loki's innocence and Tony's paternal instincts might kick in, leading to a really heart - felt relationship. There are also stories where they team up against common threats, using Loki's magic and Tony's technology in creative ways. And sometimes, the theme of growth is present, as Tony may learn to be more empathetic and Loki may learn about the value of human relationships through his interactions with Tony.
One common theme could be friendship. Since these are three distinct characters, they might form an unlikely friendship in the fanfic. For example, Loki, who is often seen as a trickster, could learn about loyalty from baby Tony and Tark.
One common theme is the exploration of their differences. Tony is a tech - savvy human, while Loki is a powerful Asgardian (sort of). Their different backgrounds lead to interesting interactions and conflicts.
One common theme is the struggle with identity. Both Loki and Tony have complex identities, and in soulmate fanfics, they often have to reconcile who they are with being soulmates. For example, Loki's status as a trickster god and Tony's playboy - genius - billionaire - philanthropist persona can create conflicts and also opportunities for growth in their relationship.
Love conquering all is also a big theme. Despite their differences and the potential obstacles in their way, like Loki's past actions or Tony's insecurities, they still manage to fall in love and get married. It's a celebration of love being stronger than any external factors.
One common theme is the 'opposites attract' concept. Tony is a tech - savvy human, while Loki is a powerful Asgardian with magic. Their differences create a lot of tension and attraction at the same time. Another theme is redemption. Often Loki has a journey of redemption, and Tony is somehow involved in that journey.
Another theme is redemption. Loki, with his past misdeeds, often finds a form of redemption through his relationship with Tony. Tony, in turn, may also find a new purpose or a more softened side to his personality. It's about two broken or flawed characters making each other better. For example, in many fics, Loki's magic and Tony's technology combine in interesting ways to solve problems, symbolizing their union.
Another theme is the challenges they face, both internally and from the outside world. Society's reaction to such an unusual situation is often a part of these fanfictions. For example, how their friends and allies react to Tony's condition. And also, they have to deal with their own insecurities and fears. Loki might worry about being a good father, and Tony might be concerned about how this will affect his identity and his role in the world.
The theme of acceptance is also prevalent. They come from different worlds, literally. Asgard and Earth have very different cultures and values. But as soulmates, they have to accept each other's differences. This can be seen in how they interact with each other's friends and families in the fanfictions. For instance, Tony introducing Loki to the Avengers and Loki introducing Tony to his Asgardian allies.
One common theme is redemption. Loki often has a troubled past, and in these fanfictions, his adoption by Tony becomes a path towards redeeming himself.
One common theme is the clash of personalities. Lady Loki is often portrayed as cunning and mischievous, while Tony is known for his brashness and intelligence. Another theme is the exploration of power dynamics. Since both characters have their own forms of power, it's interesting to see how they interact. For example, Lady Loki's magic against Tony's technology.
