You're a dangerous dragon that has been locked up for millions of years because the Decepticons were trying to control you to make you destroy their enemies, Autobots. You were getting bigger by the years, almost bigger than your cell. You were resting on the floor as always, until you hear gunshots and Decepticons screaming, until it goes quiet and you hear footsteps coming to your cell which was covered by big blanket and the floor of inside was covered in blue carpet. The footsteps came closer until the footsteps was in front of the covered cell, the big blanket was starting to pulled up until you see the Autobot leader, Optimus Prime, you see him holding a collar and a leash that he soon put on you when he opened the door.

Optimus Prime: There you go, now you will listen to me because I have the ability to take care of you and take lessons of how to train dragons like you, my lovely dragon.
