|“|| Hey, look at you! Mr. Hood! Or do you prefer Red? You know, I used to wear an outfit a lot like that. Mine was more flashy maitre d' than motorcycle fetish. You kids today...

|“||Wow! That looked like it really hurt. Whop, now hang on, that looks like it hurt a lot more. So let's try and clear this up, OK pumpkin? What hurts more? A? Or B? Forehand? Or backhand? Ah, ah, ahh! A little louder, lamb chop? I think you may have a collapsed lung. That always impedes the oratory [Robin spits in his face] Now, that was rude. The first boy blunder had some manners. I suppose I'm going to have to teach you a lesson so you can better follow in his footsteps. Nah, I'm just gonna keep beating you with this crowbar.||„|
|~ Joker torturing Jason Todd.|
The Joker is the tertiary antagonist of Batman: Under the Red Hood, albeit the one most directly responsible for the events of the film.
He is a sadistic, manipulative, uncompromising, and psychopathic clown-like terrorist of Gotham City and Batman's most widely known villain.
|“||No! Please, don't! Stay away! It's a set up! Wait! I'm not a crook, I swear!||„|
|~ The Red Hood pleads with Batman before falling.|
The Joker kidnaps Jason's eight under-bosses, and then proceeds to betray the Black Mask by placing him among the under-bosses (as they formerly worked for Black Mask), and holds them hostage inside the truck, also crashing the truck on the bridge and causing a spectacle causing the GCPD to arrive and news reporters to swarm in on the breaking report, also dousing the underbosses and Black Mask with gasoline with the intention of torching them. However, his lighter ended up acting temperamental as Jason arrives and reveals that his previous actions were designed to lure the Joker away from the safety of Arkham so that he could kill him, also making clear they had met before. He ultimately manages to light it before dropping it into the truck, with only the timely arrival of Batman foiling the torching attempt. However, Joker was freed from the Batplane's restraints by Jason, who proceeded to abduct him in turn. At a secluded apartment in Crime Alley, Joker was beaten by Jason, who cryptically alludes to Joker's earlier torture of him being responsible for his existence when Joker inquired about how they knew each other. He forces Batman to either kill him, kill the Joker directly, or otherwise let Jason kill the Joker. Batman refused the offer, and threw a batarang into Jason's gun barrel, detonating it, with Joker taking amusement in how, despite Batman finding a way to win, "everybody still loses." After Jason activated a bomb set to a 20 second timer that would kill all three, Joker prevents Batman from disarming the bomb, maniacally declaring that he'll be "the only one who gets what he wants tonight!" while pinning Batman down. However, he is knocked unconscious by Batman, and managed to save himself, Jason and the Joker. While Jason escapes, Batman takes the Joker back to Arkham.
- Unlike most animated incarnations of the Joker, where they are given a high-pitched voice, this incarnation speaks with a much deeper (although nonetheless somewhat humorous) voice.
- Similarly, unlike most incarnations of the Joker, who were usually depicted as extremely thin, this incarnation was given a more built, slightly imposing figure.
- To date, this is one of the darkest animated incarnations of the Joker character.
- Although regarded as the tertiary villain, he is still far more evil, smarter, more sadistic and dangerous than the Red hood and also taken by the fact that he is Batman's arch-nemesis and also drives the plot of the story.
- In Batman's flashback to his encountering the man who would become the Joker, the man is seen yelling "Please, no! Stay away! It's a set-up! Wait..." and "I'm not a crook, I swear!" while attempting to unmask himself, implying that he had the same backstory as the one given in Batman: The Killing Joke, or at the very least a similar backstory.
- Elements of this rendition for the Joker were reused in at least three other renditions:
- Joker from The Dark Knight Returns Part 2 proceeded to kill Dr. Wolper in a similar manner to how Joker in Under the Red Hood murdered one of Black Mask's armed guards, via slitting the latter's throat with a shard from a cup he smashed earlier (in this case, a novelty mug for the show). In the original comic, Wolper had been murdered by his neck being snapped by one of Joker's robotic henchmen.
- Jerome Valeska from the Gotham Season 2 episode Gotham proceeded to douse a bus full of cheerleaders with ship fuel and then attempted to set the bus on fire as one of his first crimes upon being broken out of Arkham Asylum, only to be delayed long enough to be stopped largely because of a tempermental lighter, just like the Joker from Under the Red Hood did, in that case dousing gasoline inside a crashed transport truck on both Black Mask, Ms. Lu, and Black Mask's former drug dealing associates.
- Joker from Batman: The Killing Joke animated film, when he encountered Batman while acting as the Red Hood, proceeded to trip over his cape while attempting to plead for his life and fall over a railing into a chemical drainage vat below with Batman attempting to reach out for him as he fell, similar to Joker in Under the Red Hood. In the original comic, Joker instead deliberately jumped into the vat in a desperate effort to escape Batman.
