Kowalski, Analysis - She's technically not even ten years old. ( ͡° ͜ʖ ͡°)

Skipper, Android 21 here is a Artificial Human Clone of Dr.Gero's late wife and thus her creation date is under 10 years, however she was created in the form of an adult and given the proportionate of one to match.

Once again Skipper she only under 10 in physical age, not mental or Biological age, as she is a clone of an adult. Her form and mind are a match to that of her base, with some generic alterations. So wouldn't call it pedophillia as is basically Dr. Gero's wife in a new body. As for the amount of porn her body and personality appeal to a wide array of fetishes.
