When Disney XD first announced a show about five different Hulks living in a house together like some radioactive reality TV crew, people were skeptical. I mean, how do you even write for a team where everyone’s primary solution is hitting things? But Hulk and the Agents of S.M.A.S.H. leaned into the weirdness, and a huge part of why it worked—or at least why it’s still fun to revisit—is the voices.
The cast of Hulk and the Agents of S.M.A.S.H. wasn't just a group of random actors. It was a weirdly perfect mix of voice acting royalty and live-action stars who actually knew their way around a recording booth.
The Big Green Guy and His Cousin
Fred Tatasciore is basically the "forever Hulk." If you've played a Marvel video game or watched a cartoon in the last twenty years, you've heard him roar. He brings this weary, "I'm trying to be a leader but my friends are idiots" vibe to Bruce Banner that makes the character feel grounded.
Then you have Eliza Dushku as She-Hulk.

Honestly, hiring Faith from Buffy the Vampire Slayer to play Jennifer Walters was a stroke of genius. She doesn't do a "monster" voice. She plays Jen as a Hollywood stuntwoman who just happens to be seven feet tall and green. It's cool because she keeps that snarky, independent edge that She-Hulk is known for in the comics, even in a kid-friendly show.
Red Hulk and the Comic Relief
Clancy Brown as Red Hulk (General "Thunderbolt" Ross) is peak casting. If you know him as Mr. Krabs, forget that. Think more like the terrifying guard from The Shawshank Redemption. His voice is like gravel in a blender. He plays Ross as this grumpy, military tactician who is constantly annoyed that he has to work with the "regular" Hulk.
- Rick Jones / A-Bomb: Voiced by Seth Green.
- The Vibe: High-energy, fourth-wall breaking, and a bit much sometimes.
- The Twist: Seth Green also produced a lot of stop-motion stuff (Robot Chicken), so he brings a frantic comedic timing to the blue guy.
A-Bomb is the one holding the camera for the "web series" gimmick the show used. It was a very 2013 way to tell a story, but Seth Green makes the dialogue feel snappy rather than just annoying.

Skaar: The Wild Card
Ben Diskin voiced Skaar, and it’s a role that required a lot of range. Skaar starts off as a double agent working for the Leader before eventually becoming the "teenage barbarian" of the family. Diskin has to jump between being a brooding loner and a guy who barely understands how Earth works. It’s a lot different from his roles in things like Codename: Kids Next Door, which just shows how versatile the guy is.
Why the Cast of Hulk and the Agents of SMASH Stayed Consistent
One thing Marvel Animation did right during this era (around 2013–2015) was keeping the voices consistent across different shows. This same cast of Hulk and the Agents of S.M.A.S.H. would frequently pop up in Ultimate Spider-Man or Avengers Assemble. It created this "connected universe" feel long before everyone was sick of that term.
James Arnold Taylor played The Leader, the main villain. You probably know him as Obi-Wan Kenobi from The Clone Wars. Hearing the voice of a Jedi Master play a big-brained, ego-maniacal gamma villain is pretty wild. He makes the Leader sound sophisticated, which is a great foil to the "smash first" mentality of the heroes.

The Guest Stars You Forgot
The show didn't stop with the main five. They brought in some heavy hitters for one-off episodes.
- Adrian Pasdar as Iron Man (reprising his role from Avengers Assemble).
- Drake Bell as Spider-Man.
- Robin Atkin Downes as Annihilus.
- J.K. Simmons as J. Jonah Jameson (because you can't have anyone else play that role).
It felt like a party. Even if the writing was geared toward a younger audience, the performances were top-tier. They treated the source material with respect, even when they were doing goofy stuff like Hulk playing mini-golf.
Fact Check: Was it Cancelled?
There's often confusion about why the show ended after two seasons and 52 episodes. It wasn't necessarily because of bad ratings; Marvel was shifting their animation strategy. They moved toward the Guardians of the Galaxy series and eventually integrated the Hulks more into the broader Avengers cartoons rather than giving them a standalone clubhouse.
Basically, if you're looking to rewatch it, keep an ear out for the chemistry. You can tell these actors were often in the booth together. That "family" dynamic isn't easy to fake, especially when you're playing giant green monsters.
