Not by our own hands, of course. Either you're forged or constructed cold. With the former, our Sparks are born when pulses from Vector Prime - in the center of our planet - fertilize the birthing fields of Cybertron. Our metal bodies come into form in the following hours.

Otherside, your fully-formed body is manufactured at a facility, and your Spark is spliced from another's. That was more common in our later history.

[That is incorrect, but Scorponok was not around to learn the truth of the source of the souls of those construction cold.]
