Of the various mercenary warriors that the Mongolian court hired during ROCH, Ma Gorn Jor was, by far, the weakest. It's said that he really didn't have much martial arts to speak of...just devastating muscular strength.
So just how bad was Ma? Could he defeat Yeung Teet Sum from LOCH in one-on-one combat? Can he handle one of the weaker members of the Gong Nam 7 Freaks (i.e. not Ohr Jen Ngok or Chu Chung) one-on-one?
