One common theme is power and control. Megatron is a powerful figure, and having a human as a 'pet' allows exploration of how he exerts his power over a much weaker being. Another theme is the unexpected bond that can form between two very different entities. Despite their differences, the human and Megatron might develop a relationship that defies expectations.
Well, a major theme is the idea of loyalty. The human may show loyalty to Megatron in different ways, and Megatron may or may not reciprocate in his own way. Also, there is often the theme of the human's influence on Megatron. Since the human is so different from the Transformers, their presence can start to change Megatron's views and actions. For example, the human might introduce concepts like mercy or a different way of strategizing to Megatron. This can lead to interesting character development for Megatron throughout the fanfiction.
In these fanfictions, a common theme is the exploration of different cultures. The human represents Earth's culture, and Megatron represents the Cybertronian culture. Their interactions can show clashes and fusions of these two cultures. Additionally, the theme of survival is often present. The human has to survive in the dangerous world of the Transformers, especially under Megatron's 'ownership'. This can lead to the human using their wits and unique abilities to stay alive, which in turn can impress or annoy Megatron, further developing their relationship.
One common theme is power dynamics. Megatron is a powerful being, and when paired with a human, the contrast in power is striking. Another theme is the idea of understanding across species. Since they are so different, the fanfictions often explore how they can begin to understand each other.
A common theme is the idea of companionship. Just like in regular human - pet relationships, the human and the Transformer - pet in these fanfictions often rely on each other for emotional support. For example, a lonely person might find a Transformer that fills the void in their life.
Well, I know a fanfiction titled 'Megatron and the Human's Adventure'. In this story, the human that Megatron has as a pet gets involved in Megatron's grand plans in a rather unique way. It shows how the human's presence starts to influence Megatron's decisions over time. There is also 'A Human in Megatron's World' which focuses on the human's perspective of being Megatron's pet and how they adapt to the strange world of the Transformers.
Power is a common theme. Female Megatron is often depicted as seeking power, whether it's over other Transformers or in a more general sense. Another theme is identity. Since she's a different take on the traditional Megatron, the fanfiction often explores who she is and how she differs.
Power dynamics is a common theme. Megatron is the powerful leader and Starscream is often vying for power, which creates an interesting relationship in the fanfictions. There's also loyalty and betrayal, as Starscream has a history of trying to overthrow Megatron in the original lore.
The theme of unexpected alliances also pops up frequently. Given their history as enemies, the idea of them coming together for a common goal is a popular one. It creates a lot of drama and interesting character development as they have to learn to trust each other despite their differences.
Another common theme is power dynamics. Megatron is the leader, and Soundwave is his subordinate, but in some fanfictions, they have a more equal relationship in certain aspects, like when it comes to strategic planning. Their different abilities and how they use them in relation to each other also play into this theme.
One common theme is redemption. Writers often explore the idea of Megatron being redeemed through his interactions with humans. For example, a human's kindness might make him reevaluate his violent ways.
The theme of transformation is also seen. Megatron, who is typically a villain, may transform (not just physically but also in terms of character) because of his relationship with Raf as a 'pet'. He could become more empathetic or at least less of a purely evil entity, which makes for an interesting character arc in these fanfictions.
One common theme is redemption. Megatron has a long history of being a villain, and in many fanfictions, Bumblebee becomes the catalyst for his possible redemption. For example, in stories where they are stranded together, Bumblebee's positive attitude might start to make Megatron question his actions.
