Dyzzleberry Dictionary ::

A form of martial arts popular on Planet Authair.  Kan-Du is performed by only Authairian males who are trained to use their claw as the weapon of defense only in the event of threat to life. Kurl Tszargon and Gore Andriol are Kan-Du Masters. 

Being at the top in both sports, the famous Kan-Du master traveled around Authair officiating at competitions, amassing crowds simply for the opportunity to see both him and Black Lightning, as the public dubbed his sporty flier.
