Brief History
According to one story, his brain patterns were based on his friend Scooby-Doo. Maybe Scoob had eaten something from Shaggy’s stash beforehand. Dynomutt has been Blue Falcon’s sidekick for years. He is also close friends with Mystery, Inc., especially Scooby-Doo who has served as Dynomutt’s personal “sidekick” a few times.
Dynomutt was voiced by The God of Cartoon Voices, Frank Welker, in his TV appearances.
