RG 1/144 Wing Gundam Zero

The Wing Gundam Zero is the TV based Zero, while the angel winged version is the Endless Waltz remodeled Wing Gundam Zero Custom.
Originally they were the same in lore, but now the rocket pod version is the predecessor, while the Custom gained its angel wings from the Tallgeese Flügel.

The only Master Grade equivalent (not counting the 1995 version) is the MG Gundam Wing Proto Zero Endless Waltz version, which is also a very good kit.

Aesthetics:
Despite being 'real' grade, the overall aesthetics are still very cartoony and not particularly realistic, which is due to Gundam Wing's overall style. Most notably the wing binders are much larger, proportionally to the body than both the MG and the anime, nearly as tall each as the body itself.

Since the Zero's colorful scheme is one of its aesthetic strong points, Bandai have kept it instead of toning it down, with a saturated red, warm yellow and a slightly dark blue, with the white being two-toned with a light grey. Additionally it has clear green parts, including color separated cameras and eyes, though you still have foil sticker options for both.
The usual RG decal sticker follows with both shaped sticker decals and plenty of shiny foil stickers.

Mechanics:
The articulation is very good with multiple clever gimmicks, such as using longer ball-joints to extend the arms out of the shoulder sockets and holding hands that lock into the wrists in order to carry the weight of the twin rifles. The large thrusters inside of the wing binders have a twist gimmick that opens or splits and closes the thruster cones. There are also flip-up shoulder gatlings and the chest has a connected opening hatch, revealing yellow vents underneath.
The wing binders have a lot of movement, which gives the overall model a ton of character with in-air poses - This in combination with two different hatch-hidden action base points (3mm peg, keeping it simple), gives it even more options.

Just like its MG predecessor model, this has a 'bird mode' where it transforms into a jet, using the shield as a nose cone/cockpit. Most notably the RG has a much more compact flight mode, while the MG is more elongated. Unlike the Wing Gundam and Custom, both the MG and RG have transforming legs, splitting the calves and pulling the feet inside to turn them into thrusters. The much larger wing binders also help balance out the appearance of the flight mode, for the better.

Equipment:
2 Twin Buster rifles, or two halves of it, that combine and have collapsible handles and extending barrels - Attaches to shield for flight mode.
1 nose cone shield - The nose extends and two small fins extend out like mini wings, used for the transformation.
2 Beam Saber Hilts, hidden inside of the shoulder pads.
2 green Beam Saber effect parts
5 hands - 2 fists, 2 locking holding hands (not sandwiched, you just slide handles into them) and 1 spread open left hand.

Conclusion:
There's no minifig, sadly, but there is a cockpit hatch under the chest gem.
This model is a 'true' 2.0 RG kit (unlike #41/#42), without any "advanced MS joint" premold parts, just like the #40 RX-78-2 2.0, with an intensely layered and highly mechanical build, full color separated transparent plastics.
I don't know what the part count is, but we are reaching the point where RG has almost as many parts as MG kits do, certainly older ones, which is why 3rd party companies have begun scaling up RG kits to 1/100 (2.0 and God Gundam with BETTER joints).
In my opinion, this is the new best RG kit, better than the Impulse and better than the Hi-Nu. Absolutely flawless.
