E63: Burning Copper

Dead Copper is the eleventh episode of Batman: Shadow War's season five.

Plot
After defeating Clayface and Deadshot, Batgirl contacted Batman to inform him of several arson crimes and the Dark Knight investigates only to find Firefly inside a burning house. The two fought and Batman attempted to pursue him in the Batmobile and has Barbara place a tracker on the pyromaniac. However, Firefly manages to escape but Barbara manages to track him down to an abandoned warehouse. After, while Batman heads there, James Gordon talks to Barbara and Barbara hides her work with Gordon warning her it is a dangerous night and, whenever he goes out, will have her under police protection.

Batman arrives at the warehouse to find Firefly, who is setting explosives around the warehouse as part of his plan to kill Batman, but the Caped Crusader catches him in the act and attempts to subdue him again. During the fight, a sword-wielding figure comes out of the darkness and wounds Firefly and disables his jetpack and knocks the detonator for the bombs out of his hands. It is revealed it is Deathstroke, who challenges Batman to a fight to the death.

Batman and Deathstroke fight intensely and violently throughout the warehouse, while Firefly is crawling to the detonator slowly and bleeding from the blade wounds. Batman realizes Firefly has the detonator and presses it despite the Dark Knight attempting to stop Firefly, causing the warehouse to explode in an attempt to kill himself and his enemies. Firefly perishes in the explosion and Batman is wounded, however Deathstroke seems untouched and continues to perform Batman's execution, raising his sword to decapitate Batman but is kicked away by Dick Grayson, who has returned as Nightwing to Batman's surprise.

Nightwing distracts Deathstroke while Batman recovers from his injuries and manages to finish the fight with Deathstroke, breaking the bo staff he was using and aggressively disarms him of his swords, then punches Deathstroke one last time to knock him out. Batman thanks Nightwing for his help and Nightwing then questions where Batgirl is, so Batman informs him of her absence. After a conversation, Nightwing leaves and hopes Batman the best.

Meanwhile, Hugo Strange is seen grinning before escaping his prison and leaving the island via boat, then calls someone to create mayhem in Arkham Asylum and allow the patients to escape.
