David Mazouz said on the Red Carpet that it wouldn't even be close.
"I'm sorry, we are at a DC Comics thing here. The Avengers are out. Justice League. I mean, come on. Martian Manhunter, Aquaman. I can't. I can't... Justice League," Mazouz said.
Mazouz also said Wonder Woman would beat Black Widow, and further offered why the Justice League would beat the Avengers.
"Because their powers are so much greater. I mean, who do the Avengers have?" the young Bruce Wayne questioned. "A guy in some iron suit, that's not even iron. It's actually bread. Then there is a big green guy. Calm on. We have Aquaman. We have Wonder Woman. We have The Flash. There's no way. Justice League's headquarter are in space. The Avengers headquarters are like somewhere in Iron Man's city. Like, who cares. It wouldn't be close."
