The Psycho Gundam Mk-II is a nearly 30cm tall model kit, with a ton of color separation, that does not use any polycaps and is made in a softer plastic.
Aesthetics:
The detail sharpness considering High Grade and the size, is very good, the heads are highly detailed with color separated eyes in a metallic pink.
The purple isn't quite one for one with the show and should've maybe been a bit darker, in my opinion.
There are a few color correction stickers, but only black ones to make the thrusters/beam cannons dark in the center. There are also the usual eye stickers, which are completely optional, since the detail is molded in - There are no decals of any kind. All in all it looks great.
Mechanics:
The overall articulation and posability is very high with double bends and some 'cheat' movement by using some of the transformation mechanics to bend legs even more. It even has an ab crunch that goes both ways.
The hands can both slide and fold off to the side to reveal gigantic beam saber/cannon slits, for which there are two effect parts and each finger can have a small beam effect part pushed in, though none for any of the weapons dotted around the mobile suit. The rear thrusters slide down and reveal reflector bits (satellite weapons) in their 'stored' version.
Most notably, the whole thing transforms into 'Fortress Mode', which is a solid block that looks like a building (it's basically its flight mode, because everything in Zeta has a flight transform gimmick).
Equipment:
2 Mega Beam Saber effect parts in clear yellow
12 (2 extra) small Beam Saber effect parts in clear yellow (for fingers)
1 huge shield that splits for the transformation and is either attached to an arm or split apart and put on the shoulders as ZZ Gundam style wing shoulders
10 + 10 stored and closed Reflector Bits
2 cables for extending the arms, Zeong style or to do a 'rocket punch' :)
1 Action Base 4 which is way too unstable for the huge model
1 set of Weapon Display Bases with arms to hold the floating hands or bits or the...
1 Broken Head Which is the destroyed version of the head that flies off like an escape pod. It looks very cool, I think I'll paint it like a miniature
+a small handful of extra parts, including a set of extra V fins!
Conclusion:
For the price of a large Master Grade, I think this is pretty fair, it's a huge HG model that feels a lot more refined than most HG models with a ton of stuff, a lot of detail/color separation and gimmicks. The build can feel a little repetitive and the plastic easily marks, but also easily cleans up due to being so soft. How well it will hold up over time, since plastic tends to settle and stick, is anyone's guess. Maybe it's really good, maybe it'll be a disaster and crack everywhere, I don't know, but as it is? It's pretty darn cool. (Match with an RG or HG Zeta Gundam, for scale).
