Karate Chop, by Daniel Zadorozny of Iconian Fonts, is a free martial arts dingbat font built from solid silhouettes of fighters in action. The figures use broad, clear poses built around sweeping kicks and raised guards.
Sports branding and arcade-style game graphics draw on the same combative imagery, though it also fits tournament posters and training apparel. For a dojo or equipment label, each fighter can act as an emblem tied to the brand.
