"Ugh. I hate this generation."
Very Old Car (Probably an Oldsmobile.)
Cliche,Stereotypical Grumpy Old Man of the Decepticons.
Mileage is very old. In fact, 'very old' would be an understatement and an insult. He's seasoned, ancient,decrepit, etc.
Mileage hates Youth. He hates everything from this generation and is struck with Nostalgia for the older times. As for the Decepticons, he hates them too. He doesn't even know why he's a Decepticon anymore.
Grey-ed the hell out.
He has many weapons systems all over his body that would even make Ironhide run.
Behind the Scenes: Edit
I don't even know what to say here, except, hell yeah I made a TF-A version of Fishie's char. Lawl.
