WARNING: The following contains spoilers for Daredevil #29, by Chip Zdarsky, Marco Checchetto, Marcio Menyz and VC's Clayton Cowles, on sale now.
While Wilson Fisk ruled the organized crime scene in New York City with an iron fist for years as the city's Kingpin of Crime, Fisk recently shocked the entire superhero community by becoming the lawfully elected Mayor of New York City. With Fisk attempting to go legitimate after taking office, there was a considerable power vacuum in the city's criminal underworld, with one of the leading crime families in the Maggia syndicate, the Libris family, taking advantage and trying to fill the void themselves.
And as the civil war between criminal empires is poised to erupt for the fate of New York, a new Kingpin is being groomed by none other than Matt Murdock's identical twin brother Mike.
Originally, Mike was a false persona created by Matt to help him continue to conceal his secret identity as Daredevil. Just as Matt was a stoic, fearless defender of the law in the courtroom, Mike was an irresponsible lout just out on the town looking for a good time. While Mike was eventually discarded by Matt as a poorly conceived attempt to maintain his secret identity, the persona took on a literal life of their own when the Inhuman Reader made the alter ego their own standalone person by accident during a team-up with Daredevil. Mike would later use the mystical Norn Stones to rewrite reality and build a life for himself, posing as Matt while Daredevil served out a prison sentence for accidental manslaughter while on the job.
Mike grows close to a young man named Butch, who is an imposingly strong figure working directly with the Libris crime family under its leader Isabelle Libris. Izzy trusts Butch, who is likely Wilson Fisk's long lost son, more than her own son Dante, especially after Butch convinced the private army of the competing crime lord the Owl to join up with the Libris family as their conflict escalated. Izzy gives Butch command of the capos and muscle that defected to the rival family, in addition to his usual responsibilities as her right-hand man and top enforcer, looking to cut Dante out of the family business to avoid losing another son to gangland violence.
Mike corners Butch and sweet talks the young mobster into dreaming bigger about his criminal ambitions, with the man visibly uncertain about his added responsibility and Izzy's willingness to be sideline her own son. Mike convinces Butch that if he were to kidnap Dante and threaten to kill him unless Izzy ceded control of the entire family's enterprise to him in exchange, he will have pulled off a bloodless coup and taken a major step towards becoming the next Kingpin of Crime, following in his father's footsteps while Fisk continues his mayoral responsibilities.
The Libris family weathered its war for New York thanks to the quick thinking of Butch, but the son of Wilson Fisk isn't satisfied with his current position in the syndicate. Goaded and coached by Mike Murdock, Butch is planning and making moves that are poised to catapult himself to the top spot of the New York criminal underworld while his father's attention is characteristically called back towards his long-standing vendetta against Daredevil. While Mike and Butch are confident that they will seize power through largely non-violent means, their grand plans are sure to go off the rails.
