Guys, Joker has beaten Superman before. And Flash. And Aquaman. And he's killed Robin, paralyzed batgirl, and tons more. Once he killed a Robin bird (yeah that's right, a bird) just because he hated Robins. And Joker can kill Batman, EASILY. But he doesn't want to because "It's just to fun". He's extremely smart too. Once he stole Mr. Mxyzptlk's powers and killed Batman millions of times. When villains want to scare each other, they tell Joker stories. I'm not saying Joker would beat anyone, but he sure would beat most people.
