In my opinion, it's quite good. The plot is well-structured, and the characters are interesting. The world-building is also impressive, adding depth to the overall story experience.
One possible fanfiction could be about Sentinel Prime and Optimus Prime having to work together to save Cybertron from a new, powerful enemy. They might start off with some differences in their approaches but gradually learn to combine their strengths.
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.
Once upon a time, Optimus Prime was resting after a long day of protecting the universe. He parked himself in a quiet corner of the Autobot base. His optics dimmed as he thought about all the battles he had won and the friends he had made. The other Autobots moved quietly around him, knowing he needed his rest. And as he drifted off to sleep, his dreams were filled with visions of a peaceful future for all.
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 other characters in the Highschool DxD world would have a wide range of reactions. The angels might see Optimus as an unknown factor and be a bit suspicious. The fallen angels might try to manipulate the situation to their advantage. And the normal human students would be terrified at first. But as the story unfolds and they see Optimus Prime's noble actions, they could start to look up to him as a hero, much like how the Autobots are seen as heroes in their own universe.
The story of Armored Core 6 involves a lot of mech battles and a complex world. You play as a mech pilot in a post - apocalyptic - like setting. There are different factions vying for power and resources. You get to upgrade your mech and engage in intense combat scenarios to progress through the story.
The Armored Core story is set in a dystopian future. It involves the use of powerful mechs called Armored Cores. Corporations fight for control and resources. Pilots engage in battles to further their company's goals. It's a complex world full of political intrigue and technological warfare.
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.
