Eronze is the only member of the Golem trio which does not learn a status move at level 64.
The members of the Golem Trio each have a different number of eyes that increase with their dex number: Eronze has 1,Erion has 2, and Erace has 3.
Like all Legendary Golems, Eronze was intentionally designed with a 4x Ground-type weakness to represent the impermanence of human triumph.
Eronze's Pokédex entry refers to Corinthian Bronze, a famous alloy of bronze from ancient Greece.
Eronze is based on artificially-created humanoids, as well as an era of man (the Bronze Age). It is also based on classical automatons seen in Greco-Roman mythology and history, as well as fire. Eronze's "face" also evokes the hole of a blacksmith's fiery kiln.
