Board Thread:Speculation, Theories, and Rumors./@comment-4383275-20140209205639

I once heard a theory from an apocryphal source concerning Shadow's origin. Apparently, "according to Sonic Battle", Prof. Gerald based Shadow's design off of the prophetic Hidden Palace mural in Sonic 3 & Knuckles. While this could feasibly make sense, since Prof. Gerald had clearly researched the Hidden Palace and ancient echidna architecture, I have found no evidence of this. Could someone help me solve this conundrum once and for all?
