That is Harley Quinn! The girlfriend of this maniac named The Joker. She is dangerous, evil and extremely strong even if you can't see any of these attributes when you look at her.
"Your little dingdong is so small and your breasts are bigger than mine HAHAHAHA"
Ashamed of yourself you try to get up and cover your package while doing so, but a big kick of her boot in your stomach drives you back to the ground.
"Hey Mister, I didn't say you can stand up! I'm not sure if I should kill you or not. I mean... you're so funny! You look so funny! I bet Mister J is dying when he sees you. Hm. Maybe.. maybe you could be one of my henchmen??? HMM? WILL YA? Hey, it's a good deal for you, honestly. You LIVE. And I'm sure that Bat-Freak is gonna die from laughter too when he sees you... nah, but you'll distract him just enough for me to kill the Bat. And when I do, my puddin' is finally gonna marry me! SOO... whattayasay?! HUH? Pleease? Pretty Pweeease?!"
You have no choice.. she means business and you know that she will just kill you like a bug if you don't become one of her henchmen... so you nod.
"AWWWWWW! THANKS THANKS THANKS THANKS!"
