Meanwhile in Gotham, Darkwing had been hunting for The Joker. She went so far as to interrogate some of his cronies, except for Harley, since she was back at the Asylum. After a few hours, she saw him. He was murdering a man with his laughing gas. "Well that was fun," he said, chuckling. "Now what should I do to him....a simple beating is not enough....something way worse..." thought Barbara. "Take your revenge on him... Do what Bruce isn't brave enough to do... For Jason..." ordered the Symbiote. Darkwing nodded and snuck up behind Joker and said, "Boo." She then kicked him to the ground. Hard. Joker looked at her and asked, "Who the hell are you?" She glared and growled, "Darkwing..." She then had her right arm turn into a sharp blade, and she slashed at him. "Sounds like a Disney ripoff.... Let's get dangerous!" taunted Joker as he got out a rubber chicken that had a brick inside it, and tried to whack her with the chicken. Darkwing then caught the chicken and threw it aside, the impact of the throw breaking the brick and the chicken. "Hey! That was my favorite chicken!" complained Joker. "We don't care....you're gonna die...." growled Darkwing as she stabbed Joker in the shoulder.

The clown chuckled and said, "Oh, I'm on your hit list? I'm flattered, doll. But you'll have to get in line!" He then tried to slap her. But Darkwing caught the hand that tried to slap her. She noticed this was his right hand. The right hand that held the gun that crippled her, ruining her life! It made her feel great rage, and she then bit his entire right hand with her razor sharp fangs. Joker screamed in pain. She then ripped his entire right hand out of his right arm with her fangs, causing Joker to scream even more. She then spit out his hand and taunted, "Your flesh tastes funny, clown. Let us tell you a joke! Stop us if you heard this one!" She then grabbed Joker, and slammed him to a wall, hard. She then smashed his face into the wall, breaking his nose. Then she did it over, and over, and over again, until his pasty white face turned into a red pulpy fleshy mess. "We'd say your face is an improvement now!" taunted Darkwing as she then had him up on his feet where she could see his back. She then shoved her entire arm into his back until her hand ripped out of his chest, holding his beating heart. "You hear that?" Darkwing rhetorically asked, "that's your spine breaking. Even if we let you live, you'd never walk again. Which would've been the best comeuppance for a monster like you. What's the matter, puddin? Aren't ya gonna laugh?!?!?!?! Don't you find this funny?!?!?!?" The dying Joker looked at his beating heart. "Guess it's not as funny when it's at your expense, is it? Funny, we didn't know you had a heart," taunted Darkwing. She then squashed his beating heart with her clawed hands. She then got her arm out of his chest, the clown fell to the ground. The Joker was now dead. Barbara, or in this case Darkwing, had finally gotten her revenge and killed the monster that ruined her life. She smiled and said, "Now that's funny."

Spider-Man then found where Darkwing was at, and seeing the bloody mess before him, he tried not to puke. If Colossus was with him, he'd definitely puke. "Barbara, what have you done?!?!?!?!?"
