Yes, there was a sci-fi novel called "Movie Character Invasion." In it, a character entered the world of "Transformers", seduced the female lead, fought alongside Bumblebee, and received the system reward "Bumblebee." In this novel, one could experience a relationship similar to that between Sam and Bumblebee. I think this novel will suit your taste very well, so I recommend it to you! I hope you like my recommendation. Muah ~
Another aspect could be that Sam starts to develop a new friendship with a human who is also interested in the Transformers. Bumblebee doesn't like this new person at all because he's afraid of losing Sam's attention. So, Bumblebee starts to act in a more possessive way, like following Sam around more closely when the new friend is around. Sam has to find a way to balance his new friendship and his relationship with Bumblebee.
Well, in a Transformers fanfiction with Sam and Bumblebee being possessive, it could be about Bumblebee being overly protective of Sam. Maybe in a battle situation, Bumblebee refuses to let any other Autobot or Decepticon near Sam because he sees Sam as his special human friend. He might even go to extreme lengths to keep Sam safe, like taking on multiple enemies by himself just to ensure Sam's well - being.
Yaoi fanfiction often explores unique relationships. In a Transformers Ratchet and Bumblebee yaoi fanfic, it might depict their deep emotional connection. Maybe it shows how they support each other during battles and rely on one another in the Autobot base. Their relationship could be shown as one of mutual understanding and unspoken feelings.
The development of their relationship could be full of twists and turns. Maybe Bumblebee is sent on a mission behind enemy lines and accidentally runs into Blitzwing. Blitzwing could capture Bumblebee, but instead of turning him in, he starts to have conversations with him. Through these conversations, they learn about each other's values and dreams. Blitzwing might start to question his loyalty to the Decepticons while Bumblebee sees that not all Decepticons are completely bad. This could lead to a very unique and evolving relationship between them.
In a Transformers and Bumblebee crossover fanfiction, Bumblebee could lose his memory and the other Transformers have to help him regain it while also protecting him from the Decepticons who see this as an opportunity to take him out. They go on a journey through different planets and encounter various strange species along the way.
One possible fanfiction could be about a female Bumblebee's origin story. Maybe she was created in a secret Autobot lab, different from the traditional male Bumblebee. She could have unique abilities that set her apart, like being able to communicate with certain alien species that the other Autobots can't. This would add an interesting dynamic to the Transformers universe as she helps the Autobots in their fight against the Decepticons in ways that were previously unimagined.
Once upon a time, there was a bumblebee transformer. He met a female transformer on a mission. They fought side by side against the Decepticons. During the battle, they started to notice each other's unique features. Bumblebee was attracted by her courage and quick thinking. After the battle, they often met to share their experiences. And gradually, love blossomed between them.
One possible fanfiction could be about Baby Bumblebee's first adventure. Maybe he gets separated from the other Autobots and has to find his way back on his own. He might encounter some small challenges along the way, like crossing a stream or finding shelter from a storm.
No. Abuse in any form, even in fanfiction, is not an appropriate theme. Transformers, especially Bumblebee, is a beloved character by many, and the idea of creating fanfiction around his abuse goes against the positive and heroic image of the character. It can also be disturbing for fans who expect more positive and inspiring stories based on the franchise.
Through shared experiences. For example, if they are in a fight against a common enemy, they'll rely on each other, which deepens their bond. The male reader could use his human knowledge and creativity to help Bumblebee in tricky situations, and Bumblebee can use his strength and advanced technology to protect the reader.
