Friendship and rivalry are also common themes. They might be rivals in some aspects, but through the diary, they start to form a bond that could be considered a friendship. And there's also the theme of growth. As they write in the diary, they grow as characters, making different decisions based on what they've written and thought about.
A major theme is the exploration of their relationship. The diary provides a unique perspective on how Tom and Harry interact with each other. It can show the evolution of their feelings, from initial suspicion or dislike to something more complex like understanding, respect, or even a deeper emotional connection.
One common theme is redemption. Tom, often portrayed as a villain in the original story, may seek redemption through his relationship with Harry. For example, in some fics, Tom realizes the error of his ways with Harry's influence.
Overcoming challenges is also a big theme. The mpreg brings about many difficulties, such as dealing with the magical world's reactions, their own insecurities, and taking care of the new life. These stories usually show how they face and conquer these problems.
A common theme is the protection of the unborn child. Given that it's a mpreg situation, both Tom and Harry will be very protective. This can lead to some tense and heart - warming moments in the story. Additionally, the theme of discovery is also there. They are discovering new aspects of each other and themselves as they go through the pregnancy journey. It's not just about the physical changes but also the emotional and mental growth that comes with it.
The exploration of their complex relationship is also a major theme. They are often portrayed as enemies at first, but as the story progresses, a strange kind of attraction or respect might develop between them. This can involve themes of opposites attracting, like Harry's light - heartedness against Tom's brooding darkness.
A common theme is transformation. Since it involves animagus, the physical and emotional transformation of the characters, especially Harry, is often explored. For example, how his new form affects his relationship with Tom.
One common theme is the battle between good and evil within the context of their relationship. Since Tom Riddle is the embodiment of evil as Voldemort, and Harry is the hero, it's often explored how Harry might influence Tom or vice versa.
The theme of friendship or a complex relationship also runs through many 'harry x tom fanfic'. They are not just friends or enemies but something in - between. It could be a relationship based on mutual respect, despite their differences, or a relationship full of tension and conflict that still has a certain bond.
Power is a significant theme too. How they handle power, whether it's magical power or power over others. In some fanfics, they might share power, or compete for it, which creates interesting storylines.
One common theme is power dynamics. Given that Tom is often associated with a thirst for power, and Lucius also has his own sense of power within the wizarding world, and Severus has his own influence in different ways, and of course Harry is the Boy Who Lived with his own power. How they balance, compete, or share power among themselves is often explored.
One common theme is the alteration of destiny. Since Harry has knowledge of Tom's future as Voldemort, he often tries to change it during their time - travel encounters. Another theme is the exploration of their relationship. In a different time setting, they can develop a new dynamic that may not be possible in their original timelines. For example, they could become friends or at least gain a better understanding of each other.
