'Loki' showrunner confirms Chris Hemsworth voiced Frog Thor in latest episode

Eagle-eyed Marvel fans caught an unexpected but welcome surprise during the most recent episode of " Loki " -- Throg, a.k.a. Frog Thor.

Showrunner Kate Herron confirmed that the split-second flash of a frog in a jar dressed as the God of Thunder was, indeed, a Thor variant.

Herron spoke to the "For All Nerds" podcast and dished on things Marvel fans might have missed -- such as who voiced the animated amphibian. As it turns out, Chris Hemsworth, who plays Thor in the Marvel Cinematic Universe, returned to the studio to voice Throg.

"We recorded Chris Hemsworth for that, by the way," Herron said. "We recorded him for that. His voice going 'Ahhh!' That’s a whole new recording. Not recycled. He recorded that!"

Also, Throg almost had more screen time, according to writer Eric Martin -- who's been spilling behind the scenes secrets on Twitter.

"Comic fans will notice the Frog of Thunder in that jar," he tweeted after the latest episode premiered on Disney+ . "We actually shot a scene for the Time Theater in Ep 1 of Loki getting pummeled by Frog Thor, but had to cut it to keep things moving."

"It’s too bad, because Tom [Hiddleston] was funny as hell," he remarked.

Throg appeared in the fifth episode of " Loki ," titled "Journey into Mystery," in which the main cast was transported to an area known as The Void -- a gray space of sorts where unruly time variants are sent to be erased forever.

Throg's fate, at the moment, is currently unknown as he was trapped in a glass jar and unable to reach his weapon, Mjölnir.

Throg was first introduced during the '80s as Puddlegulp in the Marvel comics.

Marvel is owned by Disney, the parent company of ABC News and "Good Morning America."
