Zapp is generally incompetent, egotistical, boorish, vain, cowardly, sexist and short-sighted. He will often mispronounce words, such as champagne ("sham-PAGG-Enn") and guacamole ("GWACK-a-mole") in the episodes "Love's Labours Lost in Space" and " The Problem with Popplers " (respectively). Soon after first meeting him, Leela has sex with him out of pity. He mentions this encounter repeatedly in later episodes while remaining convinced that Leela lusts after him despite her opposition to the idea. He is known to make catastrophic mistakes (such as destroying D.O.O.P. headquarters in " Brannigan, Begin Again "), yet, in the public eye, he is seen as an established and reputable leader of the Earth's army. Though viewed publicly as a respected hero for his numerous military victories, almost all of these victories are against comically weak opponents or achieved through tactics that wantonly disregard the safety of his own soldiers.
