Unlike Zaku II ver. 2.0 which looks very differently from its predecessor, Gelgoog ver. 2.0 looks very similar to Ver. 1.0, but with PG-standard designs on its body
Gelgoog can be said as 'Zeon's Gundam', since its mechanical specs and performance are much higher than Zaku II's. Furthermore, it's the first Zeon MS capable to carry beam armaments. Unfortunately, it's too late for the Zeon to mass-produce Gelgoog to win the war, as too many of their veteran soldiers died in Zeon's Earth invasion campaign. Most of the pilots using Gelgoog in the last defense of A Boa Qu are inexperience to make use of Gelgoog's combat ability.
The original MG Gelgoog was launched in 1996, starting with Char's version. After that, another four Gelgoogs were made: the mass productive version, Johnny Raiden's version, Gato's unit and Char's Ver. One Year War. All of them use the same body frame, and the changes made are almost too superficial. So, it seems that in Gelgoog's case, it's not as modular as Zaku since there aren't many variations can be made from the model kit.
Nonetheless, Gelgoog is sill a famous MS, no doubt Char is one of the reason why it is so. On the other hand, there are quite a lot of spots for improvement from Ver. 1.0, mainly the movement of entire lower body, and my personal experience with the mass productive type is the shield. I hope that they either make it lighter, or improve both the arms and the back so that they can hold the shield firmly.
Of course I would go for the later, since I don't want the shield to be scaled down at all.

It's nice to see that there's a logical proportion of size between the part with or without the armor pieces on, the arm unit in this image for example
Instead of one layer of armor with a single inner frame in Ver. 1.0, Ver. 2.0 features more than one layer of interior mechanism, like the rocker thrusters behind the 'caged' frame
Inner frame for the armor itself! Cool~
