I was hoping to find fodder for my own headcanons, and instead found this tacked onto Solus Prime’s entry in the book:
’I note at this point for those of you who may be curious: the Primes, and later the Transformers, do not have gender in the same way that humans and certain other biological species do Here Solus Prime, and those who were later formed in her lineage, are referred to as ‘she’ in order to comply with your human gender reference terms and to show a distinction that Cybertronians recognize among themselves (though other races do not).
To Cybertronians, there are two distinctive ‘kinds’ that we easily divide yourselves into, recognizing key feature differences in the manner in which information is processed. It is widely supposed among the remaining Primes that this difference was necessary for Solus herself to operate the Creation Lathe, which required a vast capacity for wide-ranging and parallel thought processing.
After becoming part of a wider galactic community, we adopted the habit of using a gender reference protocol when interacting with gendered alien species in order to demonstrate that we are not unfamiliar with the notions of difference and equality; we recognize our difference; we celebrate our equality.
In early, pre-contact Cybertronian notation, however, all Primes and others are referred to by a single symbol. I note that in human terms there is a rough 1:1 ratio of male to female that does not correspond to our 1:12 distinction, and I apologize to any females of the species who may feel slighted at having had their pronoun applied to the less-numerous type of Cybertronian.’
Not sure how I feel about this yet and I really have to run for work, so I guess I have time to think about it.
There’s fuel here and also some disappointing things…if nothing else comes out of this Covenant, though, I have come to terms with Solus’ Robot Ponytail.
