The mighty Devastator is the tallest transformer I have ever owned – about 17 inches, it is a combiner of 6 Constructicons after all. This is the Takara Tomy version from Japan, which I think is better than the Hasbro version from US: a) The green is very similar to the G1 toy; b) They have elbows; c) Each has their own gun.
Scale wise, it is voyage size. Although it is not a Masterpiece but these Constructicons certainly look good with other Masterpiece transformers! Besides, they are easy to transform and good qualities. My only complaint is the Mixmaster, it is just weird that the orientation of the cement drum is reversed.
Finally, “Constructicons, transform into Devastator!”
