For some time now, I've implied through some of my post that Wheelie's sidekick was the Mercedes E550 (the E550 is a whole different character).
It's not.
My bad, my apologies.
Brains is Wheelie's buddy. And what's Brain's alt-mode you ask? You'll have to wait and see.
Now many of you will think he's stating the obvious because we already know the identity of the blue Mercedes E550 to be Wheeljack. Well maybe not. When other Shoot for the Edit members brought up Wheeljack he had this to say:
Has Bay confirmed it's Wheeljack?
Here's your problem: you keep assuming the packaging and novels are the end all, be all. People assume they dictate Bay what storyline to follow, what to name characters, etc.
Until anything is officially confirm here or by Bay in the press, all bets are off.
There's no debate. His name has been chosen for quite some time now.
Speculation? Yes.
