I have 2 Cyclonuses (batches 02901 and 11271) and that "scratch" was something I noticed on my second one. Looking at both, both have the same line on his lower right chest going from to his top right to lower left, pointing to the amber trapezoid. I think that is what you are describing. It's not a scratch or a stress mark. It's a feature of the mold and plastic mix with lines in lots of places to varying degrees all over his body. It's luck of the draw.
