What heroic qualities are anti-hero, Seth Gecko, lacking?
Antihero An antihero, or antiheroine, is a protagonist who lacks conventional heroic qualities such as idealism, courage, or morality. These characters are usually considered "conspicuously contrary to an archetypal hero". Although antiheroes may sometimes do the "right thing", it is often for the "wrong reasons" and because it serves their self-interest rather than being driven by moral convictions.
Shtick A shtick (Yiddish: שטיק‎ ) (or schtick) is a comic theme or gimmick. "Shtick" is derived from the Yiddish word "shtik" (שטיק), meaning "piece"; the closely related German word "Stück" has the same meaning. The English word "piece" itself is also sometimes used in a similar context. Another variant is "bits of business" or just "bits"; comic mannerisms such as Laurel and Hardy's fiddling with their ties, or one of them looking into the camera shaking his head while the other one would ramble on. A "shtick" can also refer to an adopted persona, usually for comedy performances, that is maintained consistently (though not necessarily exclusively) across the performer's career. In this usage, the recurring personalities adopted by Laurel and Hardy through all of their many comedy films (although they often played characters with different names and occupations) would qualify as their shtick. A comedian might maintain several different shticks of this sort, particularly if appearing in a variety show encouraging development of multiple characters, such as "Saturday Night Live".
