This is my very first SD Gundam Impact gashapon. I guess this series replace the SD Gundam Custom series This impact series design focus more on action pose and has more "mature" looks. However, it has less colouring detail and with very limited or no articulation. Impact series also include SD Musha Gundam Series. Anyway, this Gundam 00 is from impact 3.
Most of the body parts can be seperated. However, the joints are no longer in cyclinder shape but with unique shape for each part; no more combination with other Gundam or Mobile Suit. Too bad =(
Photo below shows the comparison with Gundam Exia from Custom series gashapon.
