The Horsemen

History
Four Horsemen were a team of assassins created to torture, kill and replace Batman.

The team consisted of:

Lilith (Larissa Diaz) - The scout of the group, Larissa Diaz was named Lilith and would stalk the city until she located Batman and use her talents to poison the Batman, little by little, to keep his mind clouded and prevent him from performing at his peak performance, ensuring chaos would reign in the aftermath of the League's engineered earthquake.

Abaddon (Bane) - The muscle of the group, a prisoner from Santa Prisca was named Abaddon and was surgically grafted to an injection system which would fuel his muscles with an enhanced steroid concocted from the chemicals of the Lazarus Pits.

It was left to him to assist the other Horsemen in logistics and tactics, providing them with the vital intel they would need to overcome Gotham's caped crusader. Once the Batman was captured, Dumah would oversee the torture and torment of the captive Bruce Wayne, making certain that he was at his lowest before he would be released from this world.

Azrael (Jean-Paul Valley) - Given the honor of executing the Batman was Azrael, an experiment from birth overseen by the League and crafted into the ideal assassin. Once the Batman was removed from this mortal plane, Azrael would then become Gotham's new champion, helping the League to usher in a new age for the city, guided to new heights by Ra's al Ghul...
