OOC:I'm going to say this occurs before the current Battle for Violet, since it WAS my own fault that this never got posted it.
The Mechera were mechanical, yes, but far from unemotive. They retained fluid movement from their days as Organics, and while they control these shells from the comfort of cyberspace, they moved with every bit of control as they had as living creatures. Even for someone who didn't grasp the subtleties of Mechera movement, all it would take was a look at their eyes. The flashlight eyes themselves betrayed the emotion of the Mechera, whether they liked it or not, by the color displayed. While it was true that their color-to-emotion was different than most races(Red, as a example, wasn't anger but rather expressed a desire to make a deal), it wasn't all too hard to grasp the basic ones. Prevalent indeed was fear, manifested as shades of orange, the color opposite that which the Mechera used to express neutrality. While the figure walked down the street of the flying city(no city upon Violet touched the ground, for fear of despoiling its natural purity), he went largely unnoticed, or at least undisturbed. The Mechera, being close allies with both the Ferrarian Empire and Zarethians received many mages, and Mages are of course usually able to shapeshift. He was odd, but entitled to look like whatever he wanted(hell, many Mechera looked even odder in cyberspace). There was simply no reason to bother a stranger without cause, after all.
