KAOS agent working at South Street Novelty Inc. in New York's waterfront district.

When Maxwell Smart, Agent 99 and Fang are lured to the shop investigating a rubber banana peel found at the scene of Professor Dante's kidnapping, Garth manoeuvers Max into a position at the window where he can be targeted with Dante's stolen Inthermo machine being operated from Mr. Big's vessel in the harbor. As the device powers up, Fang senses that something is wrong and leaps at Garth, pushing him into position so that the beam hits him and he is disintegrated instead.

Portrayed by Kelton Garwood [Episode #1: "Mr. Big"].
