This is the SD Shining Gundam released as BB Senshi No. 132. As the first kit in the BB Senshi G Gundam series, it reproduces the design colors with solid sculpting, color separation, and seals. The kit's highlights are the Core Lander attachment/detachment feature and a variety of option parts.
First off, the Super Mode transformation gimmick — arguably Shining Gundam's biggest feature — is pulled off better than expected. Aside from the forearm armor, which is repositioned by swapping parts, everything else is reproduced with movable joints. You can also open the gimmick a bit further and add separate clear parts to put it into Shining Bird Mode.
On top of that, you can add clear parts to the beam stun gun (which has a spring-loaded projectile firing gimmick) in stages to build it up into a beam launcher or Crystal Shining Bird — and tack on the Core Lander to turn it into the Crystal Lander as well. As for articulation, the basic SD joint range is there, with an extra joint added for raising the shoulders upward, and the variety of option parts makes for some pretty fun posing options.
So this is an old-school SD kit whose appeal lies in its generous options and the range of modes it can recreate. For reference, in 1999 it was repackaged and released as the G Generation Shining Gundam— with the beam stun gun and clear parts dropped and a right hand for the Shining Finger added in their place. :-)
