One possible fanfiction could be about Optimus Prime and Megatron having to team up against a greater threat. Maybe an ancient evil from Cybertron's past resurfaces that is so powerful that their usual enmity has to be put aside. They start off distrusting each other but as they face battles together, they gradually come to respect the other's fighting skills.
Fanfiction about them can explore different universes and scenarios. For example, what if they were raised together? How would their relationship be different? It gives fans a chance to play with the established lore and create new and exciting stories that the official Transformers storylines may not explore. It also allows for deeper exploration of their motives and personalities.
One great storyline could be a story where Megatron and Optimus Prime are forced to team up against a greater threat from another universe. They have to put aside their differences and learn to trust each other. Another could be a pre - war story, exploring their relationship before they became enemies, perhaps they were once friends or comrades. A third could be a story where they are both stranded on a strange planet and have to rely on each other's unique abilities to survive and find a way back home.
To write a great Transformers Megatron X Optimus Prime fanfiction, start by thinking about the conflict. It's not just about their physical battles but also their ideological differences. Maybe in your story, they find a common ground in a new threat that challenges both of their beliefs. Next, describe their actions vividly. When they transform, when they fight, make the reader feel like they are there. Another important aspect is the development of their relationship. It could start as pure hatred but gradually turn into respect or even friendship. You can also add side characters to enhance the story, like other Autobots or Decepticons reacting to their strange new alliance or situation.
I'm not an expert in anime or movies, and I don't have enough information to answer this question. However, according to what I know about the Transformers plot, the scene of the fight between Prime and Megatron on the moon is not a plot of an anime or movie, but a plot of a Transformers comic or novel. In the Transformers comics and novels, Prime and Megatron often fought on different planets, some of which even involved the moon.
One great fanfiction could be about Optimus and Arcee going on a dangerous mission together. They face numerous challenges, like battling a powerful new Decepticon. Their teamwork and trust in each other are put to the test. Arcee's speed and agility combined with Optimus' strength make them a formidable duo. Along the way, they might have some deep conversations about the future of their race and their place in the war.
One plot idea could be Optimus Prime losing his memory and having to rediscover who he is while the Autobots try to protect him from the Decepticons. Another could be a story where Optimus Prime has to team up with an unlikely ally, like a human who has a special power that can help in the fight against the Decepticons. Or perhaps a plot where Optimus Prime travels to a different dimension and has to find his way back while facing new enemies.
If they switched sides in fanfiction, it would be a huge shock. Optimus as a 'bad guy' would be very different. He might use his leadership skills in a more tyrannical way. Megatron as a 'good guy' would be strange too. He'd have to fight his own nature of seeking power. But it could make for an interesting story as they both struggle with their new identities.
In a fanfic about Optimus Prime x Megatron, their relationship could be explored in a more philosophical way. For example, they might debate the nature of good and evil, power and responsibility. Optimus believes in protecting all life, while Megatron has his own ideas about power and how it should be used. This kind of fanfic could show how their different viewpoints could either bring them closer together or drive them further apart.
A great angle for a Megatron x Optimus Prime fanfic could be a body - swap situation. They are forced to inhabit each other's bodies due to some alien technology gone wrong. This leads to them having to understand each other's perspectives on a whole new level. They start to see the reasons behind their actions in the past and develop a new - found respect for one another.
