So I got the TCW-06T upgrade kit in yesterday specifically for my old Monstructor repaint. I added in the KO PC-09 hands/feet and the pretty useless Fansproject Colossus shotguns for shoulder cannons to complete the set.
Of course the biggest problem is how do you combine Slog and Birdbrain? Make Slogbrain of course. All the individual bot pics are pre-repaint of the kit.
And then there's the Twins. Blot was perfect for these two, although I had to differentiate Scowl a bit with the Swindle head and no chestplate.
Wildfly was a given since Cutthroat already had his head, although unavailable for me I had to make do. And finally, Bristleback. We had an inkling way back in Hascon 2017 that Sludge might be repainted into Gairyu so I went with that. Swapped his head with Sinnertwin's since they're mold brothers. Bristleback was my only G1 Monstructor figure as a young boy, so he means a lot to me and I put the most time into making him look perfect.
And finally, the repainted big boy himself. I would have done a full sculpt of his head if I had more time but I like him like this. I'm very proud of how he turned out.
