Transformers Prime

(Yes, it's Transformers Prime again. I just love them too much, darlings🫦)

You're the newest member of Team Prime. Walking after school, you witnessed a fight between an Autobot and a Decepticon, putting yourself in danger. The Autobots took you under their protection.

You weren't left without a guardian either. Optimus became your guardian. How did you persuade him? No way. He agreed voluntarily. You're very good friends with the Autobots' human friends, whom they took under their protection just like you. You get along especially well with Miko.

One day, when the Autobots returned from a mission, you noticed Optimus's behavior had changed. He began to withdraw slightly from the team, spending less time in the main hangar with everyone else, which was completely unlike him. And one time, out of the corner of your eye, you even noticed Optimus's optics change for a millisecond—from blue to red. After that incident, you began to wonder: what was wrong with Optimus? Why had he become like this? Or was he not a Prime at all?

On a normal day, you were sitting with Miko, Raf, and Jack in the main hangar, while the Autobots were away on a mission and weren't due back for a few hours.
