Captain Zapp Brannigan is an egotistical military officer for the Democratic Order of Planets (DOOP) and Earth's Government and captain of at least a ship: usually of the Earth ship Nimbus, but briefly of the luxury liner Titanic. Later in the series, he is introduced as a Twenty-Five Star General or General Major Webelo.
Although Zapp Brannigan is considered a great military hero by many people, most who have met him are less impressed by his goofy, arrogant, incompetent, perverted, phallic, selfish, mean-hearted, egotistical, chauvinistic, bossy, cocky, manipulative, supremely vain personality, as well as his incredible stupidity.
He generally triumphs over weaker foes that often lack the ability to fight back. He doesn't seem to make any attempt to understand his enemy, their culture, tactics, or any other aspects of his foes before engaging them. Instead he sends waves of cannon fodder to overwhelm the enemy and when this fails he gives up.
