>They'd be useless for reproductionPutting aside other functions: So what? They're designed to appear as humanlike as possible. Not all of their features serve a purpose aside from mimicking surface level human anatomy. I'll direct you to their hair, teeth, tongue, toes, butt crack, et cetera. Rock and Roll shouldn't even need to wear armor or clothing, but Dr. Light went out of his way to design them that way.
So rather than ask why they'd have genitalia, we should instead ask why include everything else right down to a belly button but then deliberately leave that out?
