Matthew Lillard Voices Shaggy in Groundbreaking Scooby-Doo Anime Series Coming to Tubi

Matthew Lillard is stepping back into the role of Shaggy for a landmark project: the franchise's first-ever original anime series.

The 56-year-old actor will team up with returning voice actor Frank Welker for Yokoso Scooby-Doo, a new animated show premiering on Tubi. Lillard will lend his voice to Shaggy while Welker returns to voice the beloved Great Dane himself.

Produced by Warner Bros. Animation as a Tubi Original, the series marks a historic milestone for the Scooby-Doo franchise. The show will roll out exclusively on Tubi across North America, with international audiences able to catch it on Cartoon Network.

The story takes Scooby and Shaggy on a culinary journey through Japan that quickly turns chaotic. "While visiting Japan on the ultimate foodie adventure, Scooby-Doo and Shaggy unwittingly unleash hundreds of mythical monsters that are causing trouble across the country," the synopsis explains. "With the help of Scooby's uncle, Daisuke-Doo, along with new friends, a magical girl Yume and gadget whiz Takumi, the group embarks on an all-new mystery filled with monster chasing and fun chaos."

Adam Lewinson, Tubi's Chief Content Officer, emphasized the creative ambition behind the project. "By bringing Scooby and Shaggy into a bold anime world set in Japan, we're connecting with global fandoms and delivering the kind of fun, chaotic mystery that travels across generations," he stated. "As we grow our animation slate, this is exactly our brand of fan-first storytelling—familiar, surprising, and unmistakably Tubi."

Welker has deep roots in the franchise, having voiced Fred Jones during the series' 1969 debut, Scooby-Doo, Where Are You, and has been the voice of Scooby-Doo for over two decades.

Lillard's history with the property spans both live-action and animation. He starred as Shaggy in the two live-action Scooby-Doo films beginning in 2002 and has returned to voice the character across multiple animated installments since then.
