Can anyone make out what the back of the jacket says? It looks just like a traditional outlaw motorcycle gang 3-piece back patch, with the name at the top, logo at the middle, and "territory" at the bottom. And a small patch right next to the logo that says MC (motorcycle club).
Now if you look closely at the Decepticon jacket there's also a small patch by the Decepticon logo. "MC" patch perhaps?
