My drawing of two Protoforms. A Hatchling (left), a newborn/baby, and a Sparkling (right), a growing child.
In my Transformers universe, Cybertronians have kids. But unlike humans, all Cybertronian babies are made in in facilities. After a protoform is made, they are put in sort of nurseries where they can get adopted, either by single bots or a bot couple. They have the option of donating their CNA to make specially-made protoforms just for themselves. Meaning a bot couple can have a child of their own. They also made blanks (Sparkless protoforms) to be used as spare bodies and parts.
When the Autobots and Decepticons began to split into their own race, they each made their own facility. The Autobots' facility is called the Matrix and the Decepticons' is called the Pit. This way, these Transformers can actually be born an Autobot or Decepticon. As opposed to the Cybertronians who first split away/evolve into their factions.
