Matthew Lillard is officially climbing back into the Mystery Machine once again, and longtime Scooby-Doo fans already know exactly what that means. Somewhere, a sandwich taller than the Eiffel Tower is trembling in fear while a suspicious janitor quietly adjusts his rubber monster mask backstage. The beloved voice of Shaggy Rogers is returning alongside Frank Welker as Scooby-Doo for the franchise’s wild new anime-inspired chapter, proving that some duos remain as timeless as a hallway chase sequence scored by psychedelic rock music.

For fans who grew up rewinding Scooby-Doo on scratched DVD box sets or racing home after school for Cartoon Network marathons, this feels less like a casting update and more like the return of comfort television royalty. Lillard has become so intertwined with Shaggy’s nervous cadence and lovable chaos that imagining the character without him now feels almost illegal in Mystery Inc. terms.

The confirmation that Matthew Lillard and Frank Welker will return as Shaggy and Scooby in Yokoso Scooby-Doo! instantly gives the project credibility with longtime fans. Welker has been voicing Scooby for decades and remains one of the last living bridges to the franchise’s original Hanna-Barbera roots. Lillard meanwhile has evolved into something much bigger than a nostalgic live-action casting choice. 

What makes the timing fascinating is how packed Lillard’s current career slate already is. Between appearances in the second seasons of Cross and Daredevil: Born Again alongside another nostalgic horror return in Scream 7, the actor has quietly become one of modern pop culture’s most reliable legacy stars. Yet Shaggy still feels like his spiritual home base. There is a reason fans immediately hear his voice when reading the word “Zoinks.” That vocal performance has become stitched into the franchise’s DNA like Scooby Snacks in Velma’s handbag.

Netflix Is Set to Put You on the Mystery Van’ Nostalgia by Adding Scooby Doo Movies to Its Collection

Now, instead of simply hosting the classics, Tubi is creating new ones.

Yokoso Scooby-Doo! marks the franchise’s first full anime series and perhaps its boldest tonal swing since Mystery Incorporated introduced serialized storytelling and cosmic horror mythology years ago. The new series sends Scooby and Shaggy to Japan on what begins as a dream foodie vacation before predictably spiraling into supernatural chaos involving mythical monsters. Without Fred, Daphne, and Velma around initially, the duo teams up with Scooby’s uncle Daisuke-Doo, magical girl Yume, and tech genius Takumi for a mystery adventure that sounds delightfully chaotic in the best possible way.

Veteran anime director Itsuro Kawasaki is helming the project with Francisco Paredes serving as co-producer, while Warner Bros. Animation continues backing the series after first unveiling it in 2024 under the title Go-Go Mystery Machine. The timing is especially interesting because Scooby-Doo is simultaneously preparing another live-action reinvention through Netflix. Production recently began on the streamer’s reboot series starring Maxwell Jenkins, McKenna Grace, Abby Ryder Fortson, and Tanner Hagen as the younger Mystery Inc. gang in an origin story centered around a supernatural murder mystery witnessed by a Great Dane puppy.

Whether audiences are here for ghost chases, anime spectacle, or simply hearing Matthew Lillard yell “Like, Scoob!” one more time, the franchise clearly is not slowing down anytime soon.
