What are some interesting ideas for an RWBY Transformers crossover fanfiction?

One idea could be a crossover where the Autobots from Transformers Prime end up in the world of RWBY. They could team up with the RWBY characters to fight a common enemy, like a new type of Grimm that has some technological abilities similar to the Decepticons. The Autobots' advanced weaponry and technology would be a great addition to the RWBY universe's combat.

One idea could be that Lucifer, with his charm and manipulative skills, gets involved in the power struggles among the Autobots and Decepticons. He might try to use their war for his own amusement or to gain some sort of power. For example, he could offer a deal to Megatron to help him defeat the Autobots in exchange for something valuable in the underworld.

Well, a cool concept for a Ben 10 Transformers crossover fanfiction could be that the Transformers' AllSpark has a strange effect on the Omnitrix. This makes Ben able to transform into new alien - Transformer hybrids. For instance, Four Arms could become a huge hulking form with robotic arms that can transform into different weapons. Also, the Decepticons might try to steal the Omnitrix to use its power to create more powerful soldiers. Meanwhile, the Autobots would team up with Ben to stop them. Maybe there could be a situation where Ben has to use his alien forms' unique abilities in combination with the Autobots' skills to defeat a powerful Decepticon threat.

One idea could be that Sonic and his friends accidentally stumble into the world of the Transformers. Sonic's speed could be a valuable asset in a battle against the Decepticons. For example, he could quickly deliver important messages or parts between Autobots during a fight. Another idea is that the Chaos Emeralds somehow have an impact on the AllSpark, creating new powers or challenges for both the Sonic characters and the Transformers.

Another interesting concept is to have a character crossover. For example, Bumblebee from the Animated series could somehow end up in the world of the live - action Transformers movies. His small and agile form might be a big contrast to the more bulky Transformers in the movies. He could form an unexpected friendship with a human character, like Sam Witwicky, and together they could help the Autobots in the movieverse with a mission that requires his speed and intelligence.

One possible plot could be that the Autobots and Decepticons end up on Remnant. The RWBY teams initially mistake them for new types of Grimm. But then they realize they are sentient machines. They team up with the Autobots to fight off the Decepticons who are trying to mine Remnant for its resources.

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.

One interesting idea could be a crossover between Transformers and the Harry Potter universe. Imagine Optimus Prime leading the Autobots through Hogwarts, facing magical threats alongside the wizards. Another could be a Transformers and Star Wars crossover, with the Autobots and Decepticons getting involved in the Galactic Civil War. Maybe the Transformers' advanced technology could have an impact on the balance of power in the Star Wars galaxy.

Perhaps there is a portal that connects Cybertron and Equestria. Some ponies accidentally end up on Cybertron and are shocked by the mechanical world. The Transformers have to help them get back home. Meanwhile, some Autobots are curious about the ponies' world and decide to accompany them. This leads to a cultural exchange of sorts between the two groups, with lots of misunderstandings at first but then growing respect and friendship.

One idea could be that the Autobots and Maximals team up against a new common enemy that has the ability to corrupt both mechanical and organic forms. They would have to combine their different skills and technologies to overcome this threat.
