Baby Optimus Prime's character can be developed by exploring his relationships. If he has a mentor figure among the Autobots, his interactions with that character can shape him. He might look up to this mentor and try to imitate their good qualities. His relationship with other baby Transformers or younglings can also be important. He could learn about sharing, cooperation, and friendship through these relationships. Additionally, his discovery of his own strength, both physical and mental, can be a key part of his development. For instance, when he first realizes he can lift a small object that others thought was too heavy for him, it gives him confidence.
The development of baby Optimus Prime can be centered around his growing awareness of his purpose. At first, he might just be a curious little bot, but as he experiences more, he starts to sense that he is meant for something greater. His exposure to stories of great Autobot heroes could inspire him. He could then start to practice things like leadership skills in small ways, like leading a group of young Autobots in a game or a simple mission. His character also develops through his mistakes. When he makes a wrong decision, like trusting a Decepticon in disguise, he learns from it and becomes more cautious and wise as a result.
There could be a fanfiction where baby Optimus Prime is sent to the past, to a time when the Transformers' society was very different. He has to adapt to the old ways while still holding onto his future - self's values. He might meet young versions of his future friends and enemies, and his presence starts to change the course of history in small but significant ways.
Fanfiction about Baby Optimus Prime might also explore his emotional side. As a baby, he would be more vulnerable and have a wider range of emotions. He could get scared during battles, but also be extremely curious about the world around him. Writers could delve into how the other Autobots help him deal with these emotions, like Ratchet being like a father figure, comforting him when he's afraid and guiding him as he grows.
One great fanfiction idea could be about Baby Optimus Prime's discovery of his power. Maybe he stumbles upon a small energon crystal and it gives him a little boost of power, and he has to learn how to control it. This could involve his friends like Bumblebee helping him out and teaching him the basics of being a powerful Autobot.
Another aspect is the acceptance of differences. The human reader has to accept that Optimus Prime is not human, he has different values and a different physical form. Optimus Prime has to accept the fragility and short lifespan of the human. They need to work through these differences and find common ground. For instance, they both value justice and freedom. By focusing on these shared values and gradually understanding their differences, their relationship can develop in a believable way.
It could be developed by exploring their past. Maybe there was an event in their youth that they both remember differently. As they start to talk about it in the fanfic, they begin to see each other in a new light. For instance, they might have once been friends or at least comrades in a fight against a common enemy before their ideologies split them apart. This exploration of the past can build a more complex relationship between them.
One way is to explore his relationships more deeply. For example, his relationship with Bumblebee could be developed further. Maybe there could be a story where Bumblebee is in a really tough situation and Optimus has to make a difficult choice to save him, which would show his loyalty and the lengths he would go to for his comrades.
Their relationship can be portrayed as a deep friendship with mutual respect. Optimus, as the leader, respects Arcee's skills and determination. Arcee, in turn, looks up to Optimus and trusts his leadership completely. They can also have a mentor - mentee relationship where Optimus guides Arcee in some aspects.
His sense of humor could be enhanced. For example, in a lemon - filled landscape (maybe a world where lemon trees are everywhere due to some strange experiment gone wrong), Optimus Prime could crack jokes about the sour situation they are in. This would show a more light - hearted side of him.
Optimus Prime could fit in as a powerful ally. He would be like a super - powered being in the RWBY world. His presence could shake up the power balance. Maybe he arrives through a portal and immediately starts helping the RWBY teams fight the Grimm. He could be seen as a symbol of hope, much like the Huntsmen and Huntresses are in RWBY.
In time travel fanfics, Optimus Prime often becomes more introspective. For instance, when he meets his past self or witnesses historical events, he reflects on his past decisions. This makes him more cautious in some cases, as he realizes the far - reaching consequences of his actions.
