However, after Cottonmouth's corrupt extortion leads to the tragic murder of Pop—a father figure to the community—Luke is forced out of the shadows.

As Luke disrupts illicit operations, Cottonmouth retaliates violently. Their conflict intensifies, culminating in Luke throwing Cottonmouth through a wall. However, this victory is short-lived.

corrupt politician Cornellius Stokes partner with the enigmatic arms dealer Willis Stryker, known as Diamondback.
