Anatomy of a Preggers Transformer
Obviously anyone who reads this Tumblr realizes I am something of a mechpreg plotter. Prowl is my favourite to write at the moment but I also like to knock up Ironhide, Mirage, Cliffjumper, Hound, Thundercracker, Ratchet, blah blah blah.
I settled in my head what the process looks like, but unfortunately I cannot draw worth a damn, so I figured I would explain it. While I like the human mimick method some writers go with, that didn’t fit my headcanon so I went with this.
In the chassis, the upper part of a Transformers frame, above the midsection, this is where you have a grounders bumper, etc, there is a component I am calling the forge which is located below the spark chamber, and lays compacted near flat for the majority of a Transformers lifetime. When a mech or femme kindles, buds, whatever the spark first forms over many quartexes, stellar-cycles (I’m giving my lovelies a vorn long carry term because giant alien robots that live for millions of years do not get to have a nine month term, nope sorry, you get to suffer dearies).
At the same time as the spark is developing, frame is being built in the forge, using the carrying mech or femme aka originator’s energy, resources, etc. Once the spark is fully formed, in the last stage of carrying it drops into the frame. At this stage the newling will stretch, and shift and kick inside its originator, and periodically transform into an egg shape. This goes back and forth until emergence begins when the newspark tucks into an “egg” and is pressed by the contracting forge against a slowly irising opening until the newspark basically pops out of the originator’s chassis.
There you go, my head canon.
