While Jonny Quest may have been the first character Tim Matheson voiced for Hanna-Barbera, he wasn't the last. Matheson carved out a nice niche as the studio's main actor for teenage heroes, and the most notable example after Quest himself is Space Ghost's Jace. He wasn't the initial choice for the character (newspapers from the summer of 1966 indicate Jay North was initially intended for the role), but it's hard to imagine anyone else playing him. Alongside fellow Space Ghost sidekick Jan, the duo gave the show's core demographic characters to latch onto. After all, as cool as Space Ghost is, he's not exactly the most relatable guy to a kid. Jan and Jace are, and part of that is thanks to their excellent vocal performances. Just as he did for Quest, Matheson gave Jace the perfect combination of heart and heroism.
For those who want to know more about Matheson's time at Hanna-Barbera, I cannot recommend Kevin Scott Collier's Jonny Quest Speaks: Jonny, Sinbad Jr. and Me enough. The book is exactly what you'd want with a title like that, and it's a great read if you're a fan of any of the shows he starred in. You're probably more than familiar with it if you follow Cartoon Research, but in case you've never heard of it, definitely check it out. Below is a short preview of the book, containing a portion of an interview with Matheson describing his time on Jonny Quest and the show's legacy.
