I reverted the HGUC Double Zeta back to its standard form and re-photographed it.

The standard form was also refined during the process of modifying it into the enhanced form.

I've also summarized the standard → enhanced → FA → launcher equipped versions below. This is something I wanted to do in HG, not MG, but 1/144 scale (lol).
In the original story, during the final battle with Haman Karn, it was supposed to be the enhanced form, but its appearance had reverted to the standard form, so this can be interpreted as the de facto "final battle specification" (lol).
Since I only swapped out the original parts, please excuse the "AG (Argama)" marking for the affiliation 😝
