Looks like MP44 to me! Very toony. I'm still not sold on the high waist, as I always thought of that as a function of perspective (i.e. in the shots that depict the high waist, the view is clearly from a ground-level human, not eye-level with Optimus). BUT, I'm a sucker for Optimii, so if I find myself with $100 burning a hole in my pocket, I might take a chance.
Gonna have to paint the dead eyes though. Is that due to some failed attempt at light-piping? He looks like he should be lying on a table about to turn grey.
I do like the big chest windows and broad shoulders. Based on the toony nature of the figure, I understand why it checks some boxes.
Would you believe that Gravestone (i.e. XTB Motormaster) is the only MP-style figure I've bought this year?! I've had it for months and haven't even opened it. It's never crossed my mind that I need to build XTB Menasor, as that feels like it's just going to be two hours of work.
I have XTB Springer and Kup on pre-order to replace the FT versions that are so-so, but for the most part, I have just about every character I want in this scale. MP saturation is a real thing. I might jump on a good Blitzwing, Astrotrain, or G1 faithful Bruticus or Computron. G1 MP Jumpstarters would be cool, but I've reached the point that if I never bought another TF in my life, I'd have more than enough. I did pick up G1 retro Blaster from WM the other day. He was cheaper than some of the other G1 releases, and I didn't have a G1KO of him, so I figured why-the-hell-not.
Is you new house going to have room for your toy display shrine? Gotta get that stuff out of storage....
