Thought to be damaged beyond repair, Erace was retrofitted with state-of-the-art technology. Its new, advanced body can even withstand atmospheric re-entry.
Like all Legendary Golems, Erace was intentionally designed with a 4x Ground-type weakness to represent the impermanence of human triumph.
Erace was the last legendary Pokémon to be confirmed.
The members of the Golem Trio each have a different number of eyes that increase with their Pokédex number: Eronze has 1, Erion has 2, and Erace has 3.
Erace's final design was created by a different person than the one who designed Eronze and Erion.
Erace's design is not only based on the aesthetics of the Space Age, but on those of the Digital Age, an era defined by the shift into an economy based on information technology. Its sleek exterior and display-like face invoke the design sensibilities of smartphones, computers and other current technological devices. It is also reminiscent of an astronaut's space suit.
