Kingpin

Kingpin was a major player in the first half of the Disney vs Marvel Villains war and a minor villain in the second half.

Vs Sykes
Early on in the war, Sykes informed Kingpin that he was planning on taking Kingpin's territory for himself in a gangwar. Seeking to prevent the expensive and damaging endeavour of a gangwar, Kingpin hires the Shocker to take him out. The Shocker is successful and Kingpin is left momentarily secure.

Paranoia
This temporary security is short lived, however, as he soon begins to fear that other crimelords might soon try to take his place. He hires Rhino to take down Pete, but the Rhino ultimately fails, leaving Kingpin more paranoid than ever.

When Queen Narissa is captured by Whiplash after she takes out Shocker, Whiplash gives her to Kingpin. He proceeds to keep her in a dungeon like area underneath his office. This later proves to be a risky endeavour.

Dethroned
Following Shocker's apparent death, Kingpin hires Hobgoblin as his new hitman. However, when Nathaniel begins to unleash monsters to free Narissa and Hobgoblin goes out to fight them (for double the pay, of course). Kingpin begins to regret this move and fires Hobgoblin. However, Hobgoblin isn't too happy with this and drives Kingpin out of his tower and takes it for himself, along with Kingpin's criminal empire.

Reclaiming the Throne
Following his loos of power, Kingpin kept his head low to avoid attracting the attention of the Hobgoblin and sat back in the shadows waiting for the inevitable moment where Hobgoblin is defeated. The day comes not long after and Kingpin returns to his tower to retake his criminal empire. However, Madame Medusa shows up in the hopes of taking Kingpin's empire for herself. The two engage in combat where Kingpin has the initial advantage until Medusa starts shooting her shotgun wildly in the air. Kingpin makes a tactical retreat to his helicopter, but Medusa, not willing to let Kingpin escape alive, shoots the helicopter's rear rotor, causing it to fall into the harbor an explode, apparently killing Kingpin.
