"I don't feel hot or cold well, given the intense heat I generate and the cooling necessary to keep me from overheating." Genos had plenty of sensors and such for regulating body temperature but it would do him no favors to feel the level of heat he put out. "I'm curious to see if you can generate sensation by doing that. I believe you but I rarely feel anything that isn't supposed to happen in a while, usually only when tests are being run to make sure a major new part is functioning as it should."
