It's fairly academic, but I've been wondering how you guys would want MP combiners to work. I don't know if we'd actually see any, but that's another issue entirely. By work, I mean as in how the combined form would be achieved, and the compromises with each. I think there are 3 main possible ways for MP combiners to work, as follows. Method #1: Scramble City/ Combiner Wars style In this method, all of the joints are contained within the figures themselves, with the only parts added being the hands and feet. This is probably me preferred method, as there is some challenging engineering going on, as well as very few extra parts. If possible, it would be a good thing if the hands & feet parts could be integrated into the core/ leader figure, and only be detached for combination. This is also the method most third party combiner figures use. Pros:Very few extra parts, little partsforming, adds interest to figures, more accurate to idea of combination. Cons:Integrated joints/combiner ports could lead to compromises with looks/articulation of individual figures, difficult to engineer, possible stability issues. Method #2: Entirely self contained In this method, all of the combiner parts, hands and feet are integrated into each figure. As in, the arm robots contain the hands, the leg robots contain the feet, etc. To my knowledge, there have been no 3P combiners to do this, and only 3 official figures that are not masterpiece. (RID Landfill, FOC Bruticus and G1 Liokaiser.) This method would be coolest from an engineering standpoint, but could lead to undesirable compromises with the individual figures, as seen with FOC Bruticus. This method also rules out limbs being interchangeable, ala Scramble City. Pros:No extra parts, no partsforming, adds interest to figures, Perfect Transformation Cons:Integrated parts could lead to compromises with looks/articulation of individual figures, but to an even greater extent than method 1, not show accurate, really difficult to engineer, could lead to stability issues, and lack of poseability in combined mode. Method #3: Skeleton Method Now, this one may be reaching, but actually has precedent. Looking at the G1 animation models of combiners like Menasor, very little of the combined form is actually the component robots. Most of Menasor's limbs are actually just generic blocky components, as described on his TFWiki page. With this method, most of the combiner, including the joints,the feet, the forearms, the hips and the head would be a separate skeleton, with the components mounted on it. There have been no official figures to utilize this method, but this is a popular method for customizers to make custom combiners. In that case, the custom maker users parts from Supreme class figures to make the hips, feet and forearms. This method means that there would not be any compromise in any individual figures, as they would not need to have any joints or other parts within them, but on the other hand, it looks kind of lazy, and then there is the small matter of the skeleton having nowhere to go when not in combined mode. Pros:No compromise within individual figures, as they would not need to have any integrated parts, show accurate, stable, would alleviate some scale concerns. Cons:Not particularly in line with Masterpiece ethos, lots of extra parts, probably expensive, as each figure would have a large accessory that does nothing, nowhere for parts to go when not combined, possibly lazy. So, that's what I think. Now, keep in mind that this is not about whether or not MP Combiners would ever be a thing, this is about how it would work if they were. So, what do you guys think? Which method would you prefer? Are there any insights I missed? I'd like to hear what you have to say. Edit: Whoops, I forgot to mention limb swapping. Ikkstakk mentioned it, and he does not want that. I don't fully agree. In the Masterpiece line, swapping of limbs is probably not needed, but some fans might still want it, at least within combiner teams. What do you guys think?
