2. ALTHOUGH I didn't realize there was actually supposed to be a scent pfffft let me see... Garu probably smells vaguely of liquor, lingering perfume, and lightning/electricity. I don't think space has a smell. XDD Though he might have noticeably less 'environment' smells clinging to him than others at first because he kind of lived on a space station/colony for his entire life. OH yeah there might be a bit of a metallic smell, too, most of the people in his canon have their bodies reinforced/patched up with automic, which I'm going to assume is metal-based (yay vague canons!).
