Well, in 'transformers prime meets bayverse fanfiction', a cool aspect could be the combination of the different art styles. The more detailed and 'gritty' look of the Bayverse designs with the sleeker, sometimes more anime - inspired look of Transformers Prime. This can lead to really visually appealing scenes in the fanfiction, like battles or team - up moments where the contrast in appearance makes it exciting.
Optimus Prime is usually a very popular character in these crossovers. Whether it's the version from Transformers Prime with his more stoic and wise demeanor or the Bayverse Optimus who has his own charm with his action - packed movie presence.
A really cool crossover idea would be the Avengers trying to understand the Transformers' technology. Iron Man, being a tech - genius, would be fascinated by the Autobots' transformation ability and their energy sources. He might try to reverse - engineer some of it, which could lead to some interesting plot twists. And the Hulk could be an unexpected ally in battles against the Decepticons, using his brute strength to take on the powerful robots.
One interesting crossover could be the Autobots and Decepticons getting involved in the Galactic Civil War. Maybe the Autobots side with the Rebels, using their advanced technology to help fight the Empire. For example, Optimus Prime could lead his team in a battle against Imperial forces, with his leadership skills being a great asset to the Rebellion.
One interesting concept could be the combination of different character personalities from both Transformers Prime and the animated universe in the fanfiction. For example, seeing how the more serious Optimus Prime from Prime might interact with the more light - hearted characters from the animated series. Another concept could be the new storylines that emerge from this crossover. It might involve new threats or challenges that require the combined efforts of characters from both versions.
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.
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.
There could be an exciting fanfiction where Jack meets Diobot. Maybe it would start with Jack exploring an unknown area and stumbling upon Diobot. Their encounter could be filled with suspicion at first, as Jack is cautious about new Cybertronians. But as they start to communicate, they might find common goals, like protecting the Earth from other threats.
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.
In such a fanfiction, there could be an epic battle. The Transformers with their advanced technology and weaponry might initially be confused by the werewolves' supernatural abilities. The werewolves, on the other hand, could be in awe of the large and powerful Transformers. Maybe they would form an unlikely alliance against a common enemy, like an evil Decepticon who wants to use the werewolves' power for his own gain.
Another theme is friendship. Despite their differences, Sonic and the Transformers often form strong bonds. They learn to trust and rely on each other in the face of common enemies. For example, they might fight against a powerful Decepticon together.
