More Duality/StS guff, this time involving a mirror match that's inevitably going to end with the arena so thoroughly obliterated that it'll vanish from the floor plan.
Amy Rose Prime hates her world's Metal Sonic with an intensity that few other mortals can comprehend, but if working with him is necessary to whatever goal she has to accomplish--in this case, taking down her clownshit-crazy counterpart and her pet robohog--then so be it. Metal Sonic Prime will gladly go along with it if it means Amy possibly changing her opinion of him (spoiler alert: she won't), and right now, he's not sure if he's too fond of his "other self".
Picked Neo Metal Sonic for this pic as he stature is similar to Duality!Metal's; made only a couple of deliberate changes to his design (most notably his torso), with any others being a result of a lack of decent refs. I stupidly forgot to check the Ask Duality tumblr for refs of Duality!Amy's current design, so what I drew here is probably all kinds of inaccurate.
Looking at the zoomed-out view, I think what I initially thought of as random Photoshop vomit turned out fairly well for this pic.
