Pick your transformer cover and give it a name, are you an Autobot or Decepticon by your personality?
Personally if it was Generation 1, I would say Autobot, but if it's Michael Bay and cannon then Decepticon, mostly because they are more sympathetic in my view as a nomadic race of machine explorers simply trying to resurrect their world.
NightFrost
or
NightRush
