Imma just info dump some [conceptional, not final] stuff real quick for Transformers Starfall :
It's 2055, Japan's the number one lead in the world for tech innovation. The location of main interest is Neo-saka (New Osaka), where it's the 2nd most advanced city next to Metro-tokyo. Don't expect many changes from our current time, it's only in tech and architect.
The plot follows Kai Natsumi, a teen who likes art, music, J-alt style/rock//grunge specifically, motorbike riding, space, robots and aliens. Nobody knows what happened to her parents, Yoshimoru 'Yoshi' and Juno, herself included. In the city she lives almost everyone has a materialistic, 'everything must be the same' mindset and Kai hates it. If someone has something very unique about them, they have to hide it, but 30% of the unique people would rather show it off and rebel against the materialistic hivemind, like a punk. Kai and her friends (names in progress) are one of those punks. The [N] of them actually formed a group/gang called The Outliers.
'What about the cybertronians?', you ask and to that i shall answer :
This isn't a case where it's their first time on earth, they've been living amongst humans for god knows how long. Optimus prime, the current leader, had decided to put Earth under autobot protection from the decepticons, because Megatron wants to strip earth of it's natural resources and enslave humanity, so he could take over Cybertron and the galaxy. No human knew that there where alien robots roaming around as vehicles. Well, until the night fate decided to do it's own thing.
During that night Kai was attacked by Skywarp and Thundercracker with the assistance of Ravage and Rumble, because 'If that insignificant lifeform exposes us to it's natives, it'll be a significant problem!'. In response Kai manages to take out Ravage with her favorite guitar that she carries around to play wherever she likes. Just as she was about to go on a edicius mission by going against the bigger 'cons, the autobots come in, including Optimus. Kai didn't give up fighting tho, she decided to help said autobots by distracting the 'cons. This shows Kai knows which type of alien archetypes are trustworthy or not and her standards when it come to the question 'If aliens showed up, what would you do?'. The fight was pretty short too, so it didn't take long to put a few scratches on the 'cons. After it tho Kai, still not familiar with the Autobots, thanks Optimus for 'stopping me before killing myself, i guess', states that she'll keep them a secret 'till further notice and sorta jokes it being all a dream. As she was heading towards home, Op replies with a single, soft 'hm' to which Kai took is as both a 'your welcome' and a 'thank you for the help'. That's when they've practically earned each other's respect.
Ever since then the Autobots and the Outliers have been allies and Kai has been living the dream of being friends/teammates with robot aliens.
so yeah, will post designs, or hell maybe start a fan manga -
