Nightmare Fuel: Batman: Under the Red Hood

  • Joker's absolutely brutal beatdown of Jason Todd in the opening scene.
  • Red Hood's commandeering of several gangs and drug dealing operations by arranging a meeting. One of the more skeptical dealers asks why they should work for the Hood. Cue duffel bag.
  • The Joker's almost casually brutal slaughter of four of Black Mask's gunmen, starting with just these words: "May I have some water?"
  • Jason Todd's resurrection scene and his sequential freak-out.
    • What makes it more terrifying is Vincent Martella's performance. Just imagine Phineas Flynn screaming like he's in horrible agony.
  • Black Mask's face, though not his character.
  • Red Hood shooting a Molotov cocktail that a mook was holding, setting him on fire (a sight that the audience is mercifully spared).
  • The Joker hijacking Jason's Taking You with Me gambit just so he'll get to die with Batman, proving that the Clown Prince of Crime is indeed a legitimate self-destructive lunatic.
  • Nightwing and Batman's take-down of Amazo, which involves burying bladed batarangs in his ears and affixing C-4 to his eyes before detonating it. Imagine them doing that to an actual human being...
  • One of the kills the Red Hood does: he stabs a criminal in the eye with a tazer and then turns it on full-force, short-circuiting his cybernetic eyes and blowing up his brain. While in the movie, it's done to one of the Canon Foreigner group, the Fearsome Hand of Four; in the comic, it's done to Captain Marvel baddie Captain Nazi.
