Robert Kirkman Finally Reveals Matthew Rhys’ ‘Invincible’ Role

Matthew Rhys is officially voicing Dinosaurus in Invincible. Fans had been wondering who he was playing since his casting was first teased, and now Robert Kirkman has confirmed it.

Speaking during his panel at San Diego Comic-Con 2025, the creator of the show shared that Rhys will be bringing the dangerous and unpredictable Dinosaurus to life in the upcoming season.

Rhys, known for The Americans and Perry Mason, had been announced as part of the voice cast last week when Prime Video revealed that Invincible was renewed for a fifth season.

That announcement came with a video of the cast learning the news. Fans were excited to see Rhys join the group but had no idea which character he’d be voicing, until now.

Dinosaurus is the destructive alter ego of Dr. David Anders. He believes he’s saving the world, but his solutions are deadly and extreme. Rhys will be stepping into the role as the series heads into a darker phase.

Kirkman told fans at SDCC that there’s a lot more coming.

Kirkman previously teased what fans can expect from Season 4. One of the biggest things he talked about was the Viltrumites, something fans have been asking about for a while. He said we’ll finally get more of that part of the story.

“Thragg is cast and will be in Season 4,” he said. “If you’ve been watching the show since Season 1, you might be like, ‘Hey, when is there going to be more Viltrumite stuff?’ Season 4 has more Viltrumite stuff that you might be wanting.”

He pointed out that Season 2 gave us Anissa and Nolan, and Season 3 gave us Conquest and Allen’s space story. Season 4 is going even deeper into all of that.

The cast of Invincible is stacked. Returning voices include Steven Yeun, J.K. Simmons, Sandra Oh, Seth Rogen, Walton Goggins, Gillian Jacobs, Jason Mantzoukas, Zazie Beetz, Grey DeLisle, Zachary Quinto, Chris Diamantopoulos, Ross Marquand, Khary Payton, Andrew Rannells, Kevin Michael Richardson, Ben Schwartz, Clancy Brown, Jay Pharoah, Mark Hamill, and Melise Jow.

New cast members this season include Aaron Paul, Simu Liu, Jonathan Banks, Kate Mara, Xolo Maridueña, John DiMaggio, Tzi Ma, Doug Bradley, Christian Convery, and Jeffrey Dean Morgan.

The show is produced by Robert Kirkman, Catherine Winder, David Alpert, Simon Racioppa, Margaret M. Dean, Seth Rogen, and Evan Goldberg, with Helen Leigh and Cory Walker as co-executive producers.

Season 4 is on the way, and it looks like Invincible is about to dive even deeper into the chaos.
