Released by Entertainment Weekly, the photo provides a fairly comics-accurate take on the longtime DC villain and brother of The Monitor (also played by Garrett in the Arrowverse).
Created by Marv Wolfman, George Pérez and Jerry Ordway, Mobius, aka The Anti-Monitor, made his first appearance in 1985's Crisis on Infinite Earths #2. The incredibly powerful villain served as one of the main antagonists for the event as the architect of the destruction of the Multiverse.
"He's the biggest of the biggest of the bads," Garrett said of The Anti-Monitor in July. "And if he does make an appearance in Crisis, I think that'll shut the internet down, as a fan. Like, that's just the Anti-Monitor. That's what it's all about. We'll see. You know, who knows if it's coming, but I'm looking forward to it."
