There might also be other Autobots such as Bumblebee. Bumblebee could be Harry's friend, always there to help him out in tight situations. Maybe there's a human - Autobot liaison character who helps Harry understand the Autobots better. And let's not forget, there could be some antagonists from either the wizarding world or the Decepticons' side who play important roles in driving the story forward.
Well, one possible interesting plotline could be Harry teaming up with the Autobots to fight a common enemy. Maybe there's a powerful Decepticon that threatens both the wizarding world and the Autobots' home planet, and Harry's magic combined with the Autobots' technology is the key to victory.
No, Harry Potter is not an Autobot fanfiction. Harry Potter is a distinct fantasy series centered around magic, wizards, and the wizarding world created by J.K. Rowling. It has no relation to the Autobots which are from the Transformers franchise.
One possible storyline could be that after years of war, an Autobot and a Decepticon realize the futility of their fight. They secretly meet and start to communicate. They find that they both have similar desires for their home planet, Cybertron. So they decide to work together to bring about peace, facing opposition from both their factions.
Starscream could also be a main villain in this fanfic. He is always looking for a chance to gain power and prove himself. He might see the battle of Autobot City as an opportunity to take over the Decepticons or get some valuable Autobot technology for his own gain.
One idea could be to focus on a new Autobot character arriving at Autobot City just before the battle. This character could bring a unique skill or weapon that helps turn the tide of the battle in unexpected ways.
There's really no good reason for it to be misconstrued as such. They are completely different. Maybe someone who is very confused about different fictional universes might make such a strange claim, but there are no elements in Harry Potter that could realistically be related to Autobots.
Well, an Autobot male OC could be really brave. Like he would never back down from a fight against the Decepticons, always ready to protect the weak. He might also be very loyal to his Autobot comrades, standing by them through thick and thin.
One interesting Naruto Autobot fanfiction could be about Naruto somehow getting transported to the Transformers' universe and teaming up with the Autobots. He might use his ninja skills in combination with the Autobots' advanced technology to fight common enemies.
Well, friendship is a very common theme. The human and the female autobot start as strangers but gradually become friends. Also, the idea of discovery is prevalent. The human discovers the world of the autobots through the female autobot, and the autobot discovers human emotions and values. Additionally, there are stories where they fight together against a common foe, which shows the theme of cooperation.
