Thank you guys (Sanjeev and rattanicus)! You are right; It´s like the body of the imperial Godzilla but with a generic head. Despite being a blow model It is made of a very hard plastic. It looks more bigger in person that in the photo, I know they also made a Godzilla of the same size, I hope can catch one of those too.
Imperial Godzilla bootlegs: I love the hand painting of the dark villain eyebrows and red noses. These two examples are 6in/15.25cm and 7.25in/18.5cm are both very soft vinyl, with the larger one being very thin and squishy, especially the spines: The Imperial stamps are poor quality, and almost invisible on the larger one: Anybody know if there is a Mexican bootleg of the 12" Imperial?
I've seen the yellowish one before, pretty strange paint apps on the face indeed. I think they are actually made out of rubber but im no plastic expert. As for bootlegs based on the big figures, i havent seen any. I've seen bootlegs based on a design that looks like millenium godzilla tho.
I found these minifigures of Pin Ups are made of hard plastic, I think they are a reissue made in Mexico in the 90s or two thousand with the molds of Louis Marx. I also found this translucent rubber figure, I really do not know what character it is or what year, but suddenly it gives a resemblance to green lantern, if someone knows where it is from, I will greatly appreciate the information. I bought it to feed the Ju, hahaha.
