Eric appears in the 1991 television special Lupin the Third: Napoleon's Dictionary. He is a character who becomes romantically involved with Fujiko Mine during the events of the story. His presence is primarily defined by the role he plays within the main plot, which revolves around a high-stakes car race from Madrid to Paris where the grand prize is the titular dictionary.

Information about Eric's personal background or history prior to the events of the special is not documented. Regarding his personality, he is described as someone who ultimately reveals himself to be untrustworthy, turning out to be a bad character who is in league with antagonists pursuing the same treasure as Lupin. His motivations align with those of the other opposing forces in the story, which include governmental agencies and CIA turncoats, all seeking to secure Napoleon's Dictionary for their own purposes.

Within the narrative, Eric's primary function is as a temporary associate and romantic interest for Fujiko Mine. He is later revealed to be working with McCallum, a CIA agent who betrays his own organization in an attempt to claim the treasure for himself. Eric and his co-conspirator are part of a larger ensemble of antagonists that includes various governmental representatives, which results in the special lacking a single, memorable villain. His role in the story is relatively brief, as he disappears from the plot after his betrayal is uncovered. No significant character development or arc is documented for Eric, and there is no information on any transformation or growth he undergoes. Similarly, no notable abilities, specialized skills, or unique equipment that set him apart from other characters are documented in available sources. The description of his physical appearance is not available.
