Biography
Mac Gargan is a New Yorker criminal and leader of his own criminal gang. Gargan is ready to buy futuristic weaponry from Adrian Toomes and a deal between them is scheduled. Together with some of his men, Gargan boards the Staten Island Ferry where the deal is supposed to take place. While one of Toomes' associates, Herman Schultz, deals with Gargan, they are suddenly confronted by Spider-Man. Both Gargan's men and Schultz attack Spider-Man but are defeated. During the fight, Gargan is webbed to the railing of the ferry and unable to escape when the FBI turns up. Despite the Staten Island Ferry being almost sunk, Gargan is arrested afterwards and sent to jail.

After Toomes himself has been captured, he is sent to prison himself. As it turns out, he is in the same prison Gargan is incarcarated at and the two meet in the yard. Gargan promises that there are no hard feelings between the two and that Gargan does not blame Toomes but Spider-Man for his incarcaration. Gargan claims that he has contacts outside of prison who are ready to kill Spider-Man. He mentions that he heard a rumor that Toomes knew the identity of Spider-Man but Toomes lies and claims that if he knew, Spider-Man would be dead already.
