Operatives of Mayor Wilson Fisk free Electro (Francine Frye) so that she can be part of a female version of the Sinister Syndicate. When the Sinister Syndicate is formed, Mayor Fisk gives them their first mission to capture Boomerang who has stolen something from him. When the Sinister Syndicate catches Boomerang, Beetle contacts Mayor Fisk as she is given information on where the exchange should happen. As the Sinister Syndicate plans to adjourn for the night, they hear Mayor Fisk outside stating that they are harboring a criminal and are to surrender Boomerang to him or suffer the full might of New York City. The Syndicate notices the police, the SWAT Team, the Anti-Super Squad, and low-level bureaucrats. Spider-Man arrives as well and tries to get Mayor Fisk to have the authorities stand down only for Mayor Fisk to claim that Spider-Man fell prey to Boomerang's hypnotic boomerang. Electro claims that Spider-Man is buying them some time. After reading the paper in Boomerang's hand that belonged to Mayor Fisk, Beetle tells the Syndicate that they should let Boomerang go. While Beetle claimed that she betrayed them, she did it because she is a supervillain and states that she plans to have Mayor Fisk deputize them. The rest of the Syndicate is not up with this plan. The Syndicate then assists Spider-Man against Mayor Fisk's forces. Beetle has Spider-Man evacuate Boomerang while the Syndicate fights Mayor Fisk's forces while not killing them. The Syndicate is defeated and arrested by the police.Amazing Spider-Man Vol. 5 #25-28. Marvel Comics.
