>>9961758Unicron Crotches was around that time. Back in the dark ages before Combiner Wars brought people affordable combiner teams and FansProject upgrade kits for Energon combiners were the hot new thing, kitbashers were gutting Unicrons and Primuses (Primi?) for their bodyparts, primarily the crotches but also the arms as well.
There was a big shitshow because Jin or some other kitbasher (I'm like 99% sure it was him tho) had uploaded a private video about how he customized the crotch to allow everything to connect to youtube and someone from here downloaded it and shared it with the public, with Jin threatening to sue because his hidden techniques were being shared to the public. I don't remember the full details but someone can probably explain this part better than I could.
