Originally, the first Queen-class mecha was going to be modeled after Ambrosia. However, when I first got an idea of using it for diplomatic relations, I gave an order to prepare different decorations for it.
The mecha modeled after my wife and empress was going to be the next one.
So the first mecha was a steel and stone visage of me. It mostly looked exactly like an average Princess-class mecha, but much taller—its height reached 280 meters. Princess-class mechas looked like children next to the Queen-class one.
It also didn't have a pronounced "chest", since it was modeled after me. Instead, its torso was more even.
This affected the mecha's balance—on other mechas, the chest held supplies and fuel while also acting as a counterweight to the tail. However, the Researchers led by Engine-See managed to keep the overall volume of the torso the same even with a different silhouette, so the construction didn't suffer.
