Power Rangers' Kerrigan Mahan Said Goldar's Voice Was Physically Painful At First

While some of the original "Mighty Morphin Power Rangers" cast members ended up becoming prolific actors or performers, others have remained largely tethered to their "Power Rangers" roles. For example, Bulk actor Paul Schrier remained a presence on "Power Rangers" TV series through 2017. Kerrigan Mahan, who voices main villain Goldar in the original show, essentially had it both ways — while he's voiced characters in "Family Guy" and "Halo 2," for example, he's also remained a "Power Rangers" mainstay, both as entirely new characters over the years and even reprising the role of Goldar as recently as 2019 for the video game "Power Rangers: Battle for the Grid."

Mahan detailed how he first landed the role of Goldar in an interview with Nerdy Minds Magazine. At the time, he was a part of a small number of voice actors regularly dubbing anime characters, and he and some of his co-workers in the industry were seemingly doled out "Power Rangers" parts with little prior deliberation. Mahan, therefore, didn't take the role of Goldar all that seriously, never expecting the project to last.

"So when I started the show, I realized this voice I gave it was really... not cool. It was hurting," he said. Fortunately, Mahan found a fix that allowed him to continue working on "Power Rangers" without constant pain, creating the version of character with which fans of the show are now well familiar.

Once Kerrigan Mahan learned that "Power Rangers" was a success, and would require him to commit to the character of Goldar for more than just a single episode, he spent some time working on a voice that remained true to his initial performance without causing him pain, he explained to Nerdy Minds Magazine. "I had to figure out how to make this work. So I had a little basement in Burbank, and I went down and spent about, oh, I guess an hour finding it, finding the air, getting the air rolling over the cords until it got to the point where I'm good," he said.

Some viewers, he recalled, have noticed that his voice sounds different in later episodes than it does at the show's start, and Mahan confirmed that this is indeed the case, due to this new version of Goldar he developed.

"I kinda had an unwritten rule of forty-five minutes was as long as I would record. 'Cause that was where I could keep it no problem, you know, I didn't get too tired to go on and do another job," he continued. Temperance, then, seems to have been key to Mahan's tenure as Goldar on "Power Rangers," between his reworking of what started out as a painful performance, and his commitment to never overworking while recording his lines.
