The following is an excerpt from the CBR Transcript of the Justice League Panel at San Diego Comic-Con:
Asked about increasing diversity–particularly, “where are the Asians?”–Wallace said that diversity did not have to only mean heroes, but “diverse people.” “When you look at the world around them, it’s populated by” people of every color and orientation. He added that there would be an Asian hero debuting in “Mr. Terrific.”
Lee added that “there’s a character in Justice League–a very small character–rhymes with ‘Batom.'”
Hmm. A question about Asian characters, and a small character that rhymes with ‘Batom.’
Could it be – oh, I don’t know… – Ryan Choi, the Atom?
