Davish is just an alias for DC. No, its not the marvel comics DC you are thinking of, infact, its actually
something quite strange. DC is an abbreviation for Discipline Club, of which he stands as the most prominent member, surpassing seniors and passouts himself as the greatest DC member of all
time. He single handedly defeated goku, once killed two stones with one
bird and many more godly accomplishments I can't even comprehend.
