Another important element is the exploration of the different cultures in TFA and TFP. Each has its own set of values, social structures, and ways of doing things. A good fanfiction will explore how these differences create tension or cooperation. For example, the way communication works in each universe or the hierarchy within the Autobot and Decepticon factions. It adds depth to the crossover story.
There's also 'The Convergence of Two Transformers Worlds'. This fanfic delves deep into how the different technologies and cultures of TFA and TFP would collide. It has some really cool action scenes and character development. It shows how the Autobots and Decepticons from both shows adapt to the new situation of being in a crossover world.
Starscream is another one. He's known for his ambition and treachery in both universes. In 'tfp meets tfa fanfiction', seeing how the two Starscreams interact - whether they team up against their respective Megatrons or try to outdo each other - can be really engaging for fans.
In 'tfp meets tfa fanfiction', the technology differences can be a fascinating concept. TFP has a more gritty and realistic take on the Transformers' technology, while TFA has a more cartoony and sometimes out - there approach. Fanfictions might explore how the two groups of Transformers adapt to or are amazed by each other's tech, like the TFP Autobots being intrigued by the unique transformation abilities in TFA.
One popular trope is the 'fish out of water' situation. For example, when Soundwave is crossed over into a different universe and has to adapt to new rules and characters. Another is the 'unlikely alliance' trope, where Soundwave teams up with characters he would never usually interact with in the original Tfp setting.
Well, Tumblr can be a great place too. There are many Transformers fans on Tumblr who post about their favorite fanfictions, including those involving Tfp Soundwave crossovers. You can follow relevant tags and search for blogs that are dedicated to Transformers fanfiction. Also, some Facebook groups focused on Transformers might have members sharing or discussing good crossover fanfictions with Soundwave in them.
The fanfiction might also explore the relationship between Bumblebee and Megatron in a more emotional way. Maybe Bumblebee discovers a softer side of Megatron that was hidden under all that aggression. It could be that Megatron has some regrets about his past actions, and Bumblebee becomes the one he confides in. Or perhaps Megatron sees in Bumblebee a potential future for Cybertron that he once hoped for but thought was lost. This could lead to a very unique and unexpected bond between the two characters.
One possible story could be that Bumblebee and Jazz team up for a special mission in the TFA universe. They might start off with some misunderstandings due to their different personalities. Bumblebee is young and eager, while Jazz is more laid - back and experienced. But as the mission progresses, they learn to appreciate each other's strengths and form a strong bond. For example, Bumblebee's speed could be crucial in a chase scene, and Jazz's smooth - talking could get them out of a tight spot with some other bots.
Another concept is a time - travel fanfiction. Bumblebee and Smokescreen accidentally get sent back in time. They have to figure out how to get back to their own time while also not changing the past too much. This could involve interacting with past versions of other Autobots and Decepticons.
One common theme is growth. Bumblebee is often depicted as growing from a young, inexperienced Autobot into a more mature and capable one. For example, in many fanfictions, he learns to better control his abilities and make wiser decisions.
