Another theme is the idea of a deeper connection. It could be a romantic or a very deep platonic connection. Many fanfics explore how they understand each other on a level that others in the Autobot team may not. They share glances, have private conversations that show the special nature of their relationship.
There's also a fanfic called 'Healing Hearts'. In this story, Ratchet plays a crucial role in mending Optimus after a particularly difficult battle. The author does a great job of exploring their friendship that could potentially be more. It has some really touching moments that make it a great read for fans of the pairing.
One reason for the popularity of Optimus x Ratchet fanfic is the opportunity to explore their relationship in different scenarios. Maybe in a fanfic, they get stranded on a strange planet and have to rely solely on each other. This kind of situation can bring out new aspects of their bond that we don't see in the original series.
Perhaps there's a fanfiction where the humans are using bath bombs in a large bath tub they've set up near the Autobot base. Optimus and Ratchet come across this strange activity. The humans explain that it's a way to unwind. Optimus, being the diplomatic leader, decides to learn more about this human custom. He asks the humans various questions about bath bombs, like what they are made of and why they fizz. Ratchet is more concerned about the practicality but eventually gets drawn into the fun as the humans start sharing stories about how much they love bath bombs.
Optimus x Ratchet fanfics are really interesting. They often explore the deep friendship or other possible relationships between Optimus and Ratchet. Writers can create unique storylines, like adventures where they rely on each other in difficult situations, or emotional moments that show their mutual understanding. It's a great way for fans to expand the universe of these characters.
I really liked 'Silent Conversations'. In this fanfic, the author does an amazing job of showing Soundwave's loyalty to Megatron while also being drawn to Optimus in a way that's both unexpected and fascinating. It's a slow - burn story that builds up the relationship between them gradually, with great character development.
Well, a very frequent theme is the struggle between their duties and their feelings for each other. They are warriors first, so they have to balance their personal emotions with their responsibilities towards their team. Also, the theme of growth in their relationship is common. They start from a certain point and as the story progresses, their bond deepens in different ways.
Good character portrayal is key. Since Soundwave is usually a silent and mysterious character, and Optimus is the noble leader, a good fanfic should stay true to these traits while also showing new sides as their relationship develops. For example, Soundwave might show vulnerability only around Optimus.
They could be incorporated by having the humans use bath bombs as a form of celebration. For example, when the Autobots achieve a major victory, the humans decide to have a party and use bath bombs as part of the celebration. Optimus and Ratchet are invited to join. Optimus might see it as a way to bond with the humans further, while Ratchet would be more interested in the scientific aspect of how the bath bombs work.
There's a fanfic called 'Arcee's Trust'. In this, the relationship between Optimus and Arcee is explored in a very unique way. It shows how their bond grows over time. The author does a great job of writing their dialogues, which seem very in - character. It's a great read if you like stories that focus on character development.
