Batman: Under the Red Hood (2010)

Ra’s al Ghul realizes his mistake in hiring the Joker to use him as a distraction while he destroyed Europe’s financial districts. In Sarajevo, Bosnia, the Joker brutally assaults the captured Jason Todd, the second Robin, in an abandoned warehouse with a crowbar. Jason is locked in the warehouse with a bomb, which explodes and kills him before Batman arrives. Five years later in Gotham City, a mysterious vigilante called Red Hood assembles a meeting of the city’s most prominent drug dealers. He announces a takeover of their drug trade, taking only 40 percent of the profit while offering them protection from both Black Mask and Batman – under punishment of death to anyone caught dealing drugs to children.

Batman stops an attempted theft of a shipment belonging to Black Mask, which is the advanced android Amazo. Batman destroys Amazo with the help of Jason’s predecessor Nightwing and discovers the thieves are working for Red Hood who then kills them. He chases Red Hood to Ace Chemicals, where an explosion destroys the facility. Batman and Nightwing interrogate the Joker at Arkham Asylum about Red Hood, but he denies involvement. Black Mask puts a hit on Red Hood for Amazo’s destruction. Batman and Nightwing prevent Red Hood from hijacking Black Mask’s next weapon shipment.
