10 Comics Villains Humiliated By The Joker
2. Black Mask
Batman: Under the Red Hood, while not part of the DCAU or DC Animated Film Universe, is a solid retelling of the story of Jason Todd's death and subsequent rebirth as the vigilante Red Hood.
One of the key pieces of the story is that Red Hood is warring with another member of Batman's rogues gallery, Black Mask, for control of the Gotham underworld. Watching Black Mask grow increasingly frustrated at one guy in a red mask taking out his shipments and goons is one of the highlights of the film.
Black Mask grows so desperate that he breaks the Joker out of Arkham and pays him to stop Red Hood any way possible. Even after Joker immediately kills four of Mask's henchman right in front of him, he doesn't see a problem with trying to team up with Joker.
A costly mistake.
In short order, Joker has betrayed Black Mask and his henchmen, playing them for complete fool. He ends up almost killing them all in an exploding truck, never intending to honour their deal and using them only to draw out Red Hood and Batman.
It makes you wonder why any Gotham criminals ever strike deals with The Joker.
