you know, i have to admit something to everyone who may have thought i'd be a difficult opponent in the Mortal Kombat world... i've never beaten any of the games on any difficulty higher than medium... well i think i might have beaten one or two of them on hard, but never VERY hard. pretty sorry huh? i've always mostly been a fan of the story line and fatalities/secrets... not really a big competitor though.
that being said i doubt my opinion in this thread matters that much, but if i had to choose a boss/sub-boss that i had the most trouble with, it'd have to be that ***** Moloch.
