Optimus Prime prefers a straight-forward battle, in which opponents can look one another in the eye and know that what they do is for real and forever, as adversaries should. When fighting an enemy like the Decepticons, however, he knows that more subtle tactics are often called for. Using the new powers granted him by the infusion of Allspark energy, he is ready for even the stealthiest mission. The darker colours are sensor transparent, letting him slip in unseen, often even directly under the eyes of Decepticon guards. New servos in his joints move him silently across the ground, and AllSpark powered punches let him take out enemy troops without a single pulse from his ion blaster.
