One idea could be that Soundwave is somehow infected by a symbiote, and it changes his abilities. Maybe he can now communicate in a different way or has enhanced stealth capabilities.
I'm not sure specifically as it could be a very niche and unique fanfic. It might involve elements from 'aoe 3' (Age of Empires 3 perhaps), the concept of a soundwave (which could be related to sound in the game or some sci - fi interpretation), and a symbiote (like the alien symbiotes in some fictional universes).
One idea could be the symbiote giving the human male some extraordinary powers, like enhanced strength and agility. The male then has to learn to control these new abilities while hiding them from the world. Another plot could involve the symbiote having a mind of its own and conflicting with the male's moral code. For example, the symbiote might want to take revenge on someone who wronged it in the past, but the male is against violence.
Yes, there might be some good ones out there. You can try searching on fanfic websites like Archive of Our Own (AO3). Just type in 'aoe soundwave symbiote' in the search bar and you'll likely find a few fanfics to explore.
Common themes might include transformation. Since the symbiote is involved, Soundwave is likely to go through some sort of transformation, both physically and mentally. This transformation could be related to the 'aoe' in the sense that it might be a unique form of transformation specific to that aspect of the story. Another theme could be conflict. There could be internal conflict within Soundwave as he grapples with the symbiote, and external conflict as he faces off against others in the 'aoe' world.
One plot idea could be that Soundwave and Airachnid are on a mission together and they start to develop a grudging respect for each other's skills. As they face various challenges, this respect slowly turns into an unexpected friendship. Another could be that they are both after the same powerful artifact. At first they are rivals, but then they realize they can achieve more by teaming up. And finally, they might be caught in a situation where they have to protect each other from a common enemy, which makes them see each other in a new light.
Try searching on specialized gaming fanfic communities. There are often forums or groups dedicated to Age of Empires 3 where fans share their own creations. You can also use search engines, but be specific in your search terms. For example, type in 'aoe 3 soundwave symbiote fanfic' along with the name of any potential websites you think might host it. It might take some time and patience to find it though.
Perhaps there's a situation where Cliffjumper is captured by the Decepticons, and Soundwave is assigned to guard him. Over time, they start to have conversations that make them see each other in a new light. Cliffjumper might learn about Soundwave's motives that are not entirely evil, and Soundwave might start to respect Cliffjumper's courage. This could lead to a change in their relationship and potentially even an alliance of sorts.
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.
A story could revolve around Ravage and Soundwave exploring a new planet. They discover strange new forms of energy or technology. Ravage is eager to investigate up close while Soundwave is more cautious. Their different approaches lead to some tense moments but also some great discoveries. As they interact with the new environment, they also learn more about each other and their own capabilities.
Well, a possible plot for female Peter Parker with a symbiote could involve her using the symbiote to explore new parts of the city that she couldn't reach before. The symbiote might allow her to climb higher buildings or swing faster. Also, she could have an internal conflict where the symbiote tries to influence her decisions in a more self - serving way. She has to constantly fight against this influence while still using the symbiote's power. Additionally, she might encounter other symbiote - related characters who either help or hinder her journey.
