One possible fanfiction could be that they are brothers separated at birth. Megatron is raised in a harsher part of Cybertron, which shapes his more aggressive views, while Optimus Prime is raised in a more diplomatic environment. Their reunion could be a turning point for the entire Cybertronian civilization.
In a fanfiction where they unite, it could start with a common threat that neither side can face alone. For example, an alien race invades Cybertron. Megatron and Optimus Prime realize that their brotherly bond is stronger than their differences. Together, they could form a new strategy, using both Autobot and Decepticon forces in a coordinated way to repel the invaders.
Definitely not. In the Transformers universe, Optimus Prime represents leadership, honor, and protection. Associating him with a child in an improper way in fanfiction is wrong. Fan creations should promote positive values. We can have fanfiction where Optimus Prime is a mentor or protector of children in a proper, non - inappropriate way, but not the other way around.
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.
Well, a fanfic about Optimus and Megatron can be really interesting. It might explore their complex relationship in a new and unique way. Maybe it shows them having to work together against a common enemy despite their differences. It could also delve into their different ideologies and how they might influence each other in this fictional story.
A simple fanfiction could be that Cade Yeager discovers a hidden ability within Optimus Prime that no one else knew about. This ability helps them defeat a powerful enemy that was about to destroy the Autobot base on Earth.
In some fanfictions, Soundwave might be malfunctioning and Optimus tries to help him. This creates a unique situation as they have to put aside their differences. Their interaction could show a different side of their characters, like Soundwave's vulnerability and Optimus' compassion outside of the normal Autobot - Decepticon conflict.
One could expect a lot of conflict in a fanfic like this. Optimus, representing order and justice, and Megatron, often associated with chaos and power - hungry motives, are bound to clash. However, the 'lemon' aspect might add a touch of something unexpected. It could be a metaphor for a bitter situation they are in, like a civil war among their own kind that forces them to reevaluate their stances.
One plot could be that they are on a mission in an unknown planet. They get lost and have to find their way back. During this time, they rely on each other's skills and start to understand each other on a deeper level. The lemon part could be the trust they build which is like a warm, fuzzy feeling in their relationship. For example, Bumblebee might find a way to communicate better with Optimus Prime during this tough time, and Optimus Prime in turn, protects Bumblebee more fiercely.
One common theme is adventure. They might go on missions together across Cybertron or other planets. Another theme is sacrifice, where either Optimus or the reader character might be put in a situation where they have to sacrifice something for the greater good.
