light that stuns enemies caught in the blast)—for Batman, who also appropriates Deathstroke's remote claw gun—which fires a grappling claw that itself can shoot a grapple line to another object and pull it back to where it was fired—after defeating the assassin in the Penguin's lair; and after the death of the assassin the Electrocutioner, Batman obtains the killer's taser gloves from his body, using them for the rest of the game. In the DLC content "Cold, Cold Heart", when facing Mister Freeze, Batman adopts a prototype Extreme Environment suit to cope with severe winter conditions. The suit is equipped with Thermal Gloves to melt large quantities of ice, and allows him to throw thermal batarangs that are heated to destroy icicles and other objects.

The ears on the mask serve two purposes, one to transmit commands to his troops and drones and second as psychological intimidation and mockery to the Batman. The Arkham Knight knows the influence of symbols and has adopted the
