I'd recommend 'City at War' in the bayverse tmnt fanfic world. It has a great plot that really gets into the action and relationships between the turtles. It's exciting from the start and gives a good sense of the bayverse setting.
Bumblebee was an action sci-fi adventure movie released in 2018. It was directed by Travice Knight and starred Hayley Stanfield, Jorge Landenberg Jr., John Senna, and others. The film told the story of an 18-year-old girl who found a scarred Bumblebee in an abandoned car park in a seaside town in California. The film faithfully restored the G1 setting of the Transformers series on the big screen and received widespread praise and recognition. It was also an offshoot of the Transformers movie series and was Bumblebee's first solo film. The film had its premiere in Germany in December 2018 and was released in the mainland of China in January 2019.
One great story could be 'Optimus' Redemption' which delves into Optimus Prime's internal struggle in the Bayverse. It shows his journey to regain his true self after facing numerous challenges. Another is 'Bumblebee's New Adventure' where Bumblebee embarks on a mission to save a small town from a new Decepticon threat. And there's also 'The Bayverse Alliance' which focuses on the combined efforts of the Autobots and humans to face a greater evil.

Well, Bumblebee could try to escape by building a device from the scraps he finds in Megatron's place. He's a resourceful Autobot. He might be able to create a communication device to call for help or a weapon to fight his way out. He could also look for any weaknesses in Megatron's security. Maybe there's a power source that, if disrupted, would open all the doors. Bumblebee could also try to form an alliance with some of the other captives or minions in Megatron's lair who might be disgruntled and want to escape as well.
Well, for a 'transformers bayverse crossover fanfic', you could have Ironhide as a main character. He's tough and a great fighter, which would be useful in the often - dangerous situations in a crossover. From the Bayverse, a young scientist or inventor could be a main character. They could bring a fresh perspective and new ideas to the table when it comes to interacting with the Transformers. Also, Starscream could be a main character. His ambition and treachery would add a lot of twists and turns to the story, constantly causing problems for both the Transformers and the Bayverse characters.
One idea could be having the Autobots and Decepticons end up in the Bayverse's version of Chicago during a major crisis. They could team up with the local military forces there to fight a common enemy, like an alien invasion that is different from their own Cybertronian battles. Another idea is to have a human character from the Bayverse accidentally stumble upon a hidden Cybertronian relic that has the power to transform Earth's technology in unexpected ways, leading to a race between the Transformers and various human factions to control it.
Another interesting one is 'Rise of the Bayverse OC'. In this story, the OC starts as a small - time mechanic who accidentally gets involved with the Transformers. The fanfiction gradually builds up the character's importance in the Bayverse world. It shows how the OC uses their human knowledge and skills to help the Autobots in their fight against the Decepticons. There are also some really cool scenes where the OC modifies some of the Autobots' equipment.
One key element is the relationship dynamics. Since it's Bayverse, the relationships between Autobots and Decepticons, as well as between the Transformers and humans, are crucial. In terms of the 'lemon' part, it should be written in a way that doesn't seem forced. Also, the world - building should be consistent with the Bayverse, like the look and feel of the Transformers' world, their technology, and how they interact with Earth. For example, if a story involves a Transformer falling in love with a human, how does that work in the context of their different anatomies and cultures? That's an important aspect to look for.
One common trait is courage. Male OCs often face the powerful Decepticons without flinching. For example, they might stand up to Megatron when no one else would. Another trait is loyalty. They are usually loyal to the Autobots and their cause, helping them in their fight for Earth.
