Which Mystery Inc. member exclaims 'Zoinks!'?

Which Mystery Inc. member exclaims “Zoinks!”? Shaggy. “Zoinks!” is Shaggy Rogers’ signature expression of surprise, alarm, or fear. He often shouts it when he and Scooby-Doo encounter a monster, discover a frightening clue, or realize that a chase is about to begin.

The nonsense exclamation became part of Shaggy’s recognizable speech pattern alongside his frequent use of “like,” his nervous delivery, and his habit of running away from danger. Although other characters may occasionally repeat or parody it in later productions, Shaggy is the canonical Mystery Inc. character associated with the word.

Shaggy’s frightened reactions are a major part of the show’s comic rhythm. He and Scooby usually try to avoid danger, often by hiding or running in exaggerated loops, yet they regularly help expose the culprit. “Zoinks!” is therefore closely linked to both Shaggy’s cowardly image and his enduring partnership with Scooby-Doo.
