“Supergirl” executive producer Andrew Kreisberg said that the upcoming Season 2 finale of the CW series is “probably the biggest episode” they have ever done.

In a recent interview with Entertainment Weekly, Kreisberg said that the season ender features an ample amount of spectacular fight scenes and tear-jerking moments. “We saved a bunch of money to pay for more visual effects and actually added another day to the schedule so we could make it as big as possible,” the exec producer revealed. “And yet it also has multiple get-your-Kleenex scenes. We’re really excited about it. We’re all blown away.”

The exec producer added that viewers won’t be bored watching the finale. “Say whatever you want about the finales, [but] they’re not boring,” Kreisberg said with a laugh. “It really feels like the culmination of everything we’ve been doing all season long, all the different story lines. … It all comes together.”

Plot details about the finale are being kept under wraps, but it was previously revealed that the episode will see the arrival of Superman villain, General Zod (Mark Gibbon). “It’s a great moment,” Kreisberg said of Zod’s debut appearance. “We needed a big, iconic Superman villain, and there really isn’t anybody more iconic, at least in terms of a physical opponent for Superman, than Zod.”

However, Kreisberg said in a separate interview with TVLine that Zod’s arrival in National City is more like a cameo than a full-fledged guest-starring appearance.

“It’s a bit of a fun surprise,” Kreisberg said of Zod’s 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.”

The exec producer said that Gibbon’s version of the character will have “a little bit of that Nazi uniform look you’d see in the comics in the ‘60s.” So “Supergirl’s” Zod is visually different from Stamp’s Zod who wears what looks like a martial arts kimono, and from Shannon’s version who sports a robotic armor.

“It’s definitely fun for us,” Kreisberg said of bringing Zod into “Supergirl.” “And when you see the context in which he appears, it could only be Zod in that episode.”

Late last month, Gibbon was spotted at Vancouver’s Robson Square filming his part on “Supergirl.” According to YVRShoots, Gibbon filmed a scene in which his character faces off against Kara (Melissa Benoist) and her cousin Superman. Take a look at the photos and video taken from the outdoor filming:

In the comics, Zod is a former Kryptonian military general who was exiled to the Phantom Zone for treason due to Jor-El’s efforts. When Zod survived the destruction of Krypton, he swore revenge against Jor-El’s son, Superman. Zod is a member of the Kryptonian Military Guild and the Phantom Zoners. The character, which is considered as one of the greatest villains of the Man of Steel in the comics, was created by Robert Bernstein and George Papp. He first appeared in “Adventure Comics” #283 in 1961.

“Supergirl” Season 2 finale is slated to air on Monday, May 22 at 8 p.m. EDT on The CW.
