Not picky about MP-10 height & look how many options with oversized KO's. The key word here is OPTIONS. The CW Titan Devs is too short but it has great chest proportion girth & a almost decent stand in but I had to sell it. The Toy World Constructor: Better scale than CW Titans Devs but worse proportions. I need actual MP scale combiners with the proportions exact & the quality sturdiness no QC issues. If I pay that much money for something I need to know it won't break & at least CW Devs has pegs for areas that will pop out but you can easily pop them back in. So as close we are close but no cigar. A actually MASTERPIECE COMBINER has to be at least 18 inches tall hopefully 20+ without INCLUDING the head. The HEAD should be 3+ inches tall at least depending on the character (7 combiners appeared in G1 US). For a total of 22-23" tall same size or 5 mm smaller than FT-20 Terminus Giganticus (OMEGA) that has MP-10 Optimus Prime at his knee joint which I like. So name a 3rd Party or even Takara (MP toy) already made? Example: I think 3P's have taken over the Dinobots in MP scale (Takara is backing off which makes the point TT/Hasbro drop the ball sometimes). Gigapower especially is very satisfying as the MP of my collection. So ask me any other characters already made? Also name characters you'd like to see made (G1 cartoon appearance or g1 toy catalog characters ONLY please & I'll give you a description how I think they would be Masterpiece acceptable). It's cool to be picky bc this is your hard earned money & don't be suckered in to a figure till you feel it's exactly what you want. P.S If you just buy anything/everything & have the money not to care. That's awesome for you.
