Final Fight Revenge showed Sodom's determination to resurrect Mad Gear (this gang actually seems to be the same Mad Gear in Final Fight 2) and his decision to go to Japan to find strong warriors for the new organization. The new crime syndicate was established all about the world and was held together by a powerful second-in-command-a Japanese kabuki named Retu. Rolento, Sodom's proclaimed blood brother was also being part of the criminal organization. Guy's fiancée Rena and her father Genryusai were kidnapped by them as part of a revenge plot, but this Mad Gear fell at the hands of Haggar, Maki and Carlos, three acquaintances of Guy. Mad Gear was defeated permanently.
Street Fighter Alpha 2 reveals why Sodom wasn't seen in FF2. He was attempting to find more strong warriors for the gang. He had an argument with Rolento over how the militant man had lost sight of their gang's ideals, to which Rolento snapped back that he had never lost sight, was simply trying to find a successful way to implement them. The two fought, and Sodom lost. Sodom had also attempted to recruit E. Honda and fought him in a sumo match, but failed to win the match and his objective.
After possibly fighting Honda in a friendly rematch, the Japanese aficionado met Rolento again in Street Fighter Alpha 3, where he once again lost to Rolento in another fight over their values. Despite losing, he tracked Rolento down to Shadaloo's base containing the Psycho Drive, and finds Rolento decrying it as a poor attempt to control people. Sodom realizes that Rolento did not lose sight of Mad Gear's ideals, and the two reconcile their differences. They decided to work together toward making a great utopian nation.
Sodom is a playable character in Nintendo vs. Capcom. In this game he relies on his original katanas. In his story mode he is waqnting to get back at Guy, Cody and Haggar for ruining his gang in the past. In his ending he kills Guy and becomes leader of the Mad Gear Gang. He asks several Nintendo and Capcom villains such as Jarod and Mitsuhide Akechi to join. These villains accept but then challenges Retu for leadership.
