A cool bumblebee fanfic might be set in an alternate universe where Bumblebee is a human - like form all the time and has to hide his true identity while living in a normal human neighborhood. He could be dealing with normal human problems like school or work while also having his secret Cybertronian side to manage.
Perhaps a bumblebee fanfic where he teams up with a group of young inventors. They help him upgrade his abilities and in return, he protects them from Decepticon threats. It could involve a lot of action - packed scenes with the kids using their wits and Bumblebee using his strength and speed.
One idea could be a bumblebee fanfic where Bumblebee gets lost on an alien planet and has to find his way back to his team while making new friends among the alien species. Another could be a story about Bumblebee's early days before he joined the Autobots, like his adventures as a young and inexperienced Cybertronian.
A bumblebee human fanfic could involve a bumblebee that can talk to a human and they team up to save their shared environment. The bumblebee might tell the human about the importance of certain plants for its species and they work together to protect those plants from destruction.
Well, a plot idea could be that there is a prophecy about Bumblebee and Megatron. It says that they will either bring about the end of the Cybertronian race or save it. This forces them to interact more and try to figure out what the prophecy means. Another interesting plot could be that Megatron's mind is somehow transferred into Bumblebee's body and vice versa. They have to live in each other's shoes for a while and this changes their views of each other. And then there could be a plot where a new technology is discovered that can end the war, but Bumblebee and Megatron have different ideas on how to use it, leading to a complex relationship and many conflicts.
Maybe in the fanfic, a young Decepticon who is starting to have doubts about the Decepticon cause meets Bumblebee. Bumblebee tries to convince the young Decepticon to switch sides. This could involve a series of adventures where they face challenges together and the young Decepticon slowly realizes the truth about the Autobots' noble intentions.
One idea could be a baby bumblebee getting lost in a strange new world on Earth and befriending a young human who helps him find his way back to the Autobots. Another could be baby bumblebee's first encounter with his own abilities and how he accidentally causes some chaos among the Autobots while trying to show off. Or perhaps a story where baby bumblebee discovers a hidden power within himself during a dangerous mission.
Well, one interesting idea could be their adventures together in a new, uncharted territory. They might face challenges that test their friendship and skills.
One interesting bumblebee brother fanfic could be about their adventures in a post - apocalyptic world. They might use their unique abilities to protect the remaining humans and fight against powerful enemies. For example, Bumblebee could use his speed and communication skills, while his brother could have some other special powers like enhanced strength.
One idea could be that the bumblebee has a magical adventure in a garden full of talking flowers. The flowers need the bumblebee's help to save their home from an evil weed. Another could be that the bumblebee befriends a lonely little girl who can't go outside much, and they have heart - warming encounters through her window.
One idea could be that Baby Bumblebee gets lost during a battle and Arcee is the one who finds him. She then has to protect him while they try to find their way back to the Autobot base. Another could be a story where Arcee teaches Baby Bumblebee some important combat skills in a fun and unique way. Maybe she creates a sort of training course just for him.
One idea could be that Bumblebee is taken by a group of Decepticons who plan to reprogram him. Another could be that he's taken by a secret human organization for study. Maybe he's taken by a powerful alien race to use his abilities for their own purposes.
A plot could involve Bumblebee getting damaged and losing his memory. The RWBY characters find him and try to repair him while also helping him regain his memories. As they do this, they learn about the Transformers universe and Bumblebee starts to adapt to the RWBY world, eventually using his unique abilities to help them in a big battle against a powerful Grimm horde and a new villain that has emerged.
