Between the multiple live-action DC series currently airing ("Arrow," "The Flash," "Supergirl" and "Legends of Tomorrow"), plenty of DC Comics characters have already appeared on television. During the "Flash" panel at Emerald City Comicon, "Flash" actors Robbie Amell (Firestorm), Danielle Panabaker (Caitlin Snow) and Keiynan Lonsdale (Wally West) discussed the other characters they'd like to see appear -- and also pitched a few ideas for where they'd like to pop up next.
After Lonsdale noted that he'd like to see Aqualad appear on "Flash," Amell launched into his theory -- which involves himself playing a Batman.
"This is a weird question for me, because I would pick Batman, but I would have to play him," said Amell. "I'm already dead [on Earth-1 and Earth-2], so why not? Earth-3 -- there's Batman! And he looks a hell of a lot like Ronnie Raymond!"
Amell added that he had hopes he could appear on CBS' "Supergirl," especially since his fiancee Italia Ricci recently appeared as Silver Banshee on the show. "The 'Supergirl'/'Flash' crossover was the best episode of 'Supergirl' I've ever seen. My fiancee was the Silver Banshee, which was awesome! So now I'm trying to get my way over there," said Amell. "There was the shout-out [to my character] when Grant [Gustin said to Supergirl], 'You don't know these people?' and he's like, 'Blah-blah, Firestorm?' And I was like, 'Oh, yeah!' And [Supergirl's] like 'Nope.' And I went, 'Argh!'"
Panabaker, who plays scientist Caitlin Snow on "The Flash," added that she'd also like to guest star on "Supergirl." "I want to go to 'Supergirl' so badly," Panabaker said. "And 'Legends of Tomorrow!' I feel like 'Legends of Tomorrow' has so many Flash people, And -- ohmigosh! -- Killer Frost-Caitlin and Captain Cold would totally be friends!"
"The Flash" airs on Tuesdays at 8 PM ET on the CW. "Supergirl's" season finale episode airs on Monday, April 18 at 8 PM ET on CBS.
