Samuel Fisk in the grandson of Wilson Fisk , once the Kingpin of Crime. As a child, Samuel grews up hearing his father tell and re-tell of the "Fisk Family Triumph," when Wilson Fisk defeated his nemesis Daredevil (Matt Murdock) in a game of wits, killing him. Samuel was disgusted, both by the tale of how his crimelord grandfather had slain the hero, and the pride with which his father told it. Samuel grew up, and eventually assumed control of all Fisk family interests, including a vast crime empire and several legitimate business interests. Samuel remained guilty, however, over the source of his power.
At one point, Samuel decided to atone for his family's crimes by taking up the mantle of his family's greatest enemy, Daredevil, to fight crime himself. Lacking any real skill and never one to turn his back on "the easy way out", Samuel spent a considerable portion of his family's fortune on an advanced battle suit which makes up for his lack of training and talent. This became a source of friction between Samuel and his wife, Elain, who felt that the dangerous hobby was stealing time that Samuel could have spent with his nine year old son, Sebastian, and that the crime organization that Fisk headed would kill the entire family if Samuel's activities were discovered. Eventually Elain broke down and left. Convinced that his wife loved him primarily for his money, Fisk was confident she would return.
The New york City of Fisk's age is a considerably more ordered society, and patrolling Sentinels tend to keep the peace under most circumstances. Samuel took advantage of one of his many uneventful nights on patrol by tracking down his wife, whom he found in the arms of another man. Samuel did not confront to pair, and instead took out his agression on a patrolling Sentinel. Later, with his hand nearly broken from repeatedly punching the metal Sentinel, Samuel visited one of the underworld's many "bars with no names" and confided in the bartender about the affair. When the bartender suggests that he simply kill his wife, Fisk becomes indignant, and says that they will handle the situation like civilized people. Fisk's solution is to have Elain's lover kidnapped, bound, and brought to Fisk Tower, where Fisk places a gun to the man's temple and pulls the trigger.
