While i would agree that liu Kang is the main character, They often use Scorpion as the tutorial character. His moveset is the easiest to pickup for the beginners. and he is lowkey the face of the franchise nowadays.@MeachTheMonster you seriously don't know ryu is the main character of street fighter
Liu kang is the main character of mortal kombat
Rule of thumb is the most basic and easiest to pick up and play character
If they fight like a shoto, then that's your fighting game hero
Sort of like how Cyclops or Prof X is technically main character of the X-men franchise. but Wolverine often takes the shine
