Beck completes his Villain Decay in the Breather Episode "The Greatest Villain," all leading up to this spooftastic scene. Made even funnier when you see that they're fighting in a place that's based off of Japan.
Heck, the whole episode's a concentrated mass of all the comedy they can cram into an otherwise serious show. From the gratuitious Japanese, Dorothy being a negotiator and mimicking Roger's drive-by scenes with a bicycle, Roger's bust, Beck's Crazy Awesome plan involving forks, lightning, and Roger's bust, Dastun playing Only Sane Man, Dorothy providing Ship Tease between her and Roger (she was joking), the combining robot above being destroyed in mid-pose by Big O's O Thunder in 2 seconds...the list goes on.
