A/B/O Shenanigans (JOKER DCU)

'Well, this changes everything. First off, just his luck, right? Of course the child that is now technically in his care keels over because he's just gotten his secondary biology. Second, the kid was a damn omega. Despite Joker reeaally not wanting to be responsible for this, he couldn't exactly leave the Robin out here. Not when there seemed to be no Bat-Dad about, and Joker knew first hand how omega's were treated within Gotham. Especially in heat. There are some really creepy Alpha's out there, who wouldn't think twice about their next fuck being a ten year-old. Don't get him wrong, Joker was a sick fuck too. But, well, not that fucked. Not fucked enough to leave a child defenceless against those kind of horrors of the world.'
