“It’s a bit of a fun surprise,” Kreisberg tells TVLine of Zod’s first appearance. “He doesn’t have a lot of screen time, so I can’t say our interpretation is as nuanced as either [Superman/II‘s] Terence Stamp or [Man of Steel‘s] Michael Shannon, but we did one thing to put our own stamp on it — at least visually.” He says that Supergirl‘s Zod (played by Smallville actor Mark Gibbon) will be sporting “a little bit of that Nazi uniform look you’d see in the comics in the ’60s. Visually, he has a different look from the mechanical armor that Man of Steel did, or the real spacey clothes Richard Donner’s version had. “It’s definitely fun for us,” Kreisberg says. “And when you see the context in which he appears, it could only be Zod in that episode. ”
Hopefully we will find out more soon! Stay tuned.
