Jeong will voice Dynomutt, Dog Wonder, a robot dog with mechanical robotic parts. He had his own Hanna-Barbera Saturday morning show from 1976-1977 assisting super hero Blue Falcon. Originally the series was broadcast as a half-hour segment of The Scooby-Doo/Dynomutt Hour. The robo dog and the Mystery team gang of Scooby-Doo, Shaggy, Fred, Daphne and Velma would often team up in cracking cases.

Clemons will voice Dee Dee Skyes, who was one of Captain Caveman’s “Teen Angels” and the smartest one of the group, much like Velma in the Mystery Inc. gang.

Both Jeong and Clemons join the already announced cast of Zac Efron (Fred), Amanda Seyfried (Daphne), Gina Rodriguez (Velma), Will Forte (Shaggy), Tracy Morgan (Captain Caveman), and Frank Welker (Scooby-Doo).

Jeong was most recently seen in his Netflix comedy standup special You Complete Me, Ho, starred in The Hangover franchise and Fox TV’s The Masked Singer, as well as the hit Fox celebrity singing competition The Masked Singer. He is currently working on the CBS pilot The Emperor of Malibu. Jeong is repped by ICM Partners, Aligned Entertainment and Stone Genow.
