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.
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.
I really like 'Optimus Prime's Heart'. In this fanfiction, the author focuses on the internal struggles of Optimus while also developing a romantic relationship with the reader. It's a great read if you're into character - driven stories. Also, 'The Prime and the Reader' is quite popular. It starts with an interesting encounter between the reader and Optimus and then unfolds into a story full of mystery and love.
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.
A plotline could be Sentinel Prime getting corrupted by dark energy and Optimus Prime having to fight him to bring him back to the light. It would be a battle of wills and also a test of their long - standing friendship.
Writers often develop Optimus Prime as a wise and noble leader. They show his strategic thinking in battles and his moral compass when dealing with humans. For example, he might make decisions that protect both his Autobot comrades and the humans at the same time. Bumblebee, on the other hand, is usually portrayed as more youthful and energetic. His beeping and use of radio snippets to communicate add a unique charm. Writers might have him be more impulsive at times, especially when it comes to protecting his friends, whether they are Autobots or humans.
Characterization is really important. Optimus Prime should be written true to his noble and selfless nature. The reader character also needs to be well - rounded, with their own goals and personality. In addition, the setting should be vividly described. Whether it's the desolate landscapes of Cybertron or the hustle and bustle of Earth in the Transformers' universe, it should draw the reader in. Good fanfiction in this genre also has moments of tension and resolution, like when they face a difficult battle or overcome a misunderstanding.
You can try looking on some fanfiction websites like Archive of Our Own (AO3). It has a large collection of Transformers fanfictions, and there might be some related to Optimus Prime and Megatron in the MPreg genre.
The plot could be about a power struggle. Megatron wants total control over Cybertron, but Optimus Prime stands in his way. However, instead of just fighting, there are political intrigues involved. There could be other characters influencing their decisions. Maybe some Autobots who think Optimus is being too soft on Megatron, and some Decepticons who think Megatron is being too cautious.
