alien wrestler and future men are smaller than muscle?
exogini of patatine are smaller...
I own several of the Future Man figures, and I believe they're smaller. I'm not sure about the Alien Wrestler figures, but my guess is that they are.
Personally, I believe this indicates that their molds were made from mass produced kinnikuman figures.
I also believe this is why the 2nd and 3rd series of painted reissues are all smaller. The first painted series, which is made of the same plastic as series two and three, is the same size as the original kinnikuman -- so I don't think it was the plastic that caused them to be smaller.
However, in other cases, like Exogini, I realize the size difference may stem from a plastic that shrinks.
On the other hand, what we seem to find is that, generally, kinnikuman figures made by Bandai are all the same size and tend to be grouped by trees.
While kinnikuman figures made by other companies tend to be smaller and not grouped by trees.
(Furthermore, as Matthew pointed out, Naochin has discovered at least one kinnikuman sculpt in two sizes. As each figure seems to be made of the same plastic, the size difference appears to stem from the mold each was made from.)
I'm wondering about the size of Exogini figures that come from part two, trees 1 and 2. Wouldn't it be fascinating if they were the same size as regular kinnikuman?
