A Voice That Defined Generations: James Carter Cathcart’s Pokémon Legacy
The world of Pokémon wouldn’t be quite the same without the unmistakable voices of Professor Oak, Team Rocket’s James, and the wise-cracking Meowth. For 25 years, James Carter Cathcart was the man behind those characters, lending his versatility to the English dub of one of the most beloved animated franchises ever. When news broke in 2023 that he was retiring after a battle with throat cancer, fans everywhere paused, realizing the end of an era had arrived.
Cathcart wasn’t just some background player. He was the English voice of Professor Oak—Ash’s ever-supportive mentor and iconic pseudo-granddad—right from the early ‘90s. Just as memorable, he brought Team Rocket’s James to life with flair, bouncing between silliness and genuine threat, not to mention his dynamic as one-third of the show’s most famously inept villain trio. Few fans can forget his spin on the phrase, “Prepare for trouble, and make it double!” The guy even voiced Meowth, giving the Pokémon world its own talking cat with attitude.
His impact reached far beyond Pokémon. Gamers might recognize his work as Vector the Crocodile in Sonic X and as key characters in Super Smash Bros. Brawl, two franchises with rabid fan bases of their own. There’s something special about a voice actor whose zany, heartfelt, or dramatic tones have followed so many of us from cartoon marathons to heated gaming sessions.

Behind the Mic: More Than Just a Voice
It’s easy to focus just on Cathcart’s vocal roles, but he was far more than a performer. He adapted and wrote scripts for Pokémon TV movies, making sure the English-language versions kept their heart and humor intact. His writing added new quirks and nuances that made the dub stand out, not just follow the original scripts word for word. This kind of work shaped how millions outside Japan experienced and fell in love with Pokémon. He also collaborated in advertising, lending his skills to commercials that reached well beyond the Pokémon fandom. And did you know he even dabbled in music? The guy was everywhere, quietly influencing pop culture from almost every angle.
Throughout his career, Cathcart contributed to more than 700 Pokémon episodes and 15 feature films—an astounding run. While he wrapped up his final project with the English dub of Pokémon: Ultimate Journeys, his voice and creative touch are still stitched into the fabric of the franchise. For new and old fans alike, it’s tough to imagine turning on a Pokémon episode and not hearing one of Cathcart’s characters making their entrance.
Cathcart’s retirement isn’t just a personal milestone; it signals a changing of the guard in the world of anime voice acting. There will be new voices, new writers, and more adventures. But for anyone who ever imitated a James one-liner or got teary over a heartfelt Professor Oak speech, Cathcart will always be part of what made Pokémon magic for so many years.
