In localized versions such as the Latin American Spanish dub, the character Argus Steel is named Argus Hurtado, representing the same individual. He serves as a primary antagonist in the narrative involving the Mythical Pokémon Diancie. An experienced thief, he operates alongside his daughter Millis Hurtado. Their shared goal is capturing Diancie to exploit its diamond-generating ability for wealth, driving their actions.

Argus Hurtado exhibits a notable chocolate obsession, frequently annoying Millis. Despite his criminal lifestyle centered on theft and exploitation, he displays genuine protective concern for his daughter, particularly during critical confrontations. He employs a specialized airship and a substantial arsenal including missiles, indicating preparation for their plans.

Their pursuit brings them into conflict with Ash Ketchum and his companions aiding Diancie, and rival thieves Marilyn Flame and Ninja Riot. This escalates in Allearth Forest near the Cocoon of Destruction, where Yveltal sleeps. The altercation inadvertently awakens Yveltal. Amid the ensuing chaos, Millis is targeted by Yveltal’s Oblivion Wing attack. Argus Hurtado shields her and is petrified into stone.

Following Xerneas’s intervention, which revives those petrified by Yveltal, Argus Hurtado is restored. This experience, specifically sacrificing himself for Millis, leads to significant transformation. He abandons crime entirely, later establishing a chocolate shop for a legitimate livelihood. He utilizes the Pokémon Honedge, Doublade, and Aegislash during the film’s events.
