Brak's neighbor from down the street on The Brak Show. Thundercleese is an eight-foot-tall war robot who lives in a black fortress in Brak's suburban neighborhood.

As you'd expect from Warren Street, Thundercleese talks like an eight-foot-tall war robot and acts more like another suburban resident. Besides blowing up Zorak repeatedly for pissing him off. Thundercleese's one joy in life was his pet fish, Mr. Tickles, until the day Brak accidentally hammed him to death.

NOTE: I've had a couple people suggest that mayhaps I spelt his name wrong, suggesting it's supposed to be "Thunderclese". I thought this, too, however, on the Adult Swim website (www.adultswim.com), his name is spelt as "Thundercleese"... and since that's supposed to be the official site, I'm going by that.
