During an appearance at a recent Heroes & Villains Fan Fest, Stephen Amell addressed if there was any chance that Batman's most well-known villain The Joker could appear on Arrow. Amell answered, "Well, I mean, the short answer is yes, of course. Within the DC Universe, if they are in the DC Universe, if you were to ask if Iron Man could come to Arrow, I would be like, 'Well, no, probably not.'"
Amell continued, "But of course, The Joker could come to Arrow, Batman could come to Arrow, Superman could show up on The Flash. There's a whole myriad of options because again DC and WB have a slate of films coming up, and those films happen, and maybe Arrow's still around when they're done. Or maybe there's a change and people are just like, 'You know what, let's invest in something that's doing well for us.' So you never know."
When asked who would win in a fight between Batman and Arrow, Amell replied, "Me."
Amell continued, "What do you want me to say? Well, Batman's more experienced and his costumes cooler, and Arrow's just a ripoff, so Batman would win for sure. No, I would win, absolutely."
Arrow airs on Wednesday nights at 8 PM ET on The CW.
