Satan's Claw operates as the primary antagonist in the 1972 anime's initial story arc, orchestrating schemes to steal crucial keys required for accessing a hidden treasure. This character employs lethal force to obtain these keys, driving much of the early narrative conflict through their pursuit.

To advance malevolent goals, Satan's Claw forms alliances with antagonistic forces including a Nazi faction—utilizing a weapon that dissolves people—and a vampire partner to steal radioactive materials for bomb construction. Supernatural methods further their agenda, such as distributing a potion that transforms ordinary citizens into violent criminals to fracture societal cohesion.

Kidnapping serves as a recurring tactic. Satan's Claw targets young girls essential for accessing the treasure within the Republic of Paradise and orchestrates the abduction of a prince from an exotic country with subterranean beings' assistance. A robotic entity initially acts as a formidable ally, though the partnership fractures due to the entity's self-serving motives.

The character consistently exploits supernatural occurrences and entities, leveraging Satan's apparent manifestation within a city to amplify societal violence and aligning with an imprisoned wizard. These actions position Satan's Claw as the instigator of conflicts requiring heroic intervention.

No official information exists regarding the character's origins, physical appearance, motivations beyond causing destruction, or ultimate fate beyond the documented episodes. Development across other media remains undocumented, confining the character's role to driving antagonistic plots within the specified story arc through manipulation, force, and strategic alliances.
