Sisto

First Appearance	Space Ghost Coast to Coast Spanish Translation
Performer	C. Martin Croker

Sisto Guerta is Brak's younger brother, an elementary school aged space cat who resembles his elder brother even though he wears a red outfit as opposed to his brother's blue one. In three early episodes, he would make random appearances walking across the room farting. He was killed and eaten by mothership aliens in his fourth and final appearance in the episode Pepper. Afterwards, only a picture of himself was depicted on a scratch and sniff card in the episode Sexy New Brak Show Go.

He originally appeared with Brak in Space Ghost Coast to Coast's first episode "Spanish Translation," speaking in an affect similiar to Beavis and Butt-Head from the Mike Judge series Beavis and Butt-Head. Sisto appeared in The Brak Show, with zero speaking lines, and redesigned to wear the exact same outfit as Brak, as opposed to just a similar outfit,
