There could be a story where they face a common enemy that is a threat to their entire race. Soundwave and Megatron have to put aside their differences and work together in a new way. This could involve Soundwave using his technological skills to create new defenses, while Megatron uses his leadership and combat abilities to lead the fight. Their bond could be tested and strengthened during this time.
The relationship is often depicted as one of loyalty. Soundwave is usually shown as being extremely devoted to Megatron. He follows Megatron's orders without question and is always by his side, providing support whether it's in battle or in strategic planning.
A fanfiction could focus on a time when Megatron and Soundwave are separated. Maybe Megatron has been captured by the Autobots, and Soundwave is left to lead the Decepticons in his absence. Soundwave, who is not used to being in the spotlight, has to make difficult decisions. He has to figure out how to rescue Megatron without sacrificing too many of their troops. Meanwhile, Megatron is facing his own challenges in captivity, perhaps having to deal with Optimus Prime's attempts to make him see the error of his ways. This situation could create a lot of tension and drama in the fanfiction.
Perhaps a fanfiction where Soundwave gets damaged in a fight and Megatron has to make a difficult decision about whether to risk everything to save him. It could explore their loyalty to each other. Or a plot where they are betrayed by one of their own and they have to work together to expose the traitor.
One great fanfiction could be about Soundwave's unwavering loyalty to Megatron. It might explore how Soundwave uses his unique abilities to support Megatron in battles. For example, his ability to intercept communications could give Megatron an edge in warfare against the Autobots. Another could focus on their relationship before the war, perhaps showing how they came to trust each other and form the foundation of the Decepticon leadership.
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.
There are fanfics that focus on the origin story of Megatron and Soundwave's partnership in the Transformers Prime series. It could explore how they first met and started working together. Maybe it shows Soundwave's unwavering support for Megatron from the very beginning, and how they built their strategies against the Autobots over time.
Perhaps there could be a story where an ancient Cybertronian threat resurfaces. Megatron and Soundwave must team up with some unlikely allies, like a group of Autobots who also realize the severity of the situation. Throughout the story, Megatron and Soundwave would have to navigate their relationship with these former enemies while also dealing with the new threat. Their different personalities and motives would add depth to the story as they try to protect Cybertron together.
Well, some fanfictions might focus on their loyalty to each other within the Decepticon ranks. For example, in a story I read, Megatron relied on Soundwave's unwavering support during a difficult battle against the Autobots. Soundwave's ability to gather intelligence was crucial for Megatron's strategies, and this formed the basis of their deep bond in the fic. It showed how they complemented each other in the context of the war.
There are fanfictions where Soundwave helps Megatron see a different perspective on the Decepticon cause. For example, when Megatron is about to make a hasty and perhaps unwise decision, Soundwave steps in with his logical analysis. This not only showcases their bond but also how they complement each other in leadership and strategy.
One interesting story could be about Soundwave's secret missions. He might be sent on a mission to retrieve a powerful artifact. Along the way, he encounters unexpected allies and enemies, and has to use his unique abilities to outwit them all.
