This will piss off a lot of his fans, but I cannot stand Johnny Cage. Never liked him, never will. I don't even like him in MK2011 classic or not. He's annoying, stupid comic relief that deserves all the fatalities done to him and then some.
Runners Up:
-Mokrap (don't even need to say why)
-Meat (disgusting abomination...even the updated Kabal and his cheese grated skin is prettier)
-Bo Rai Cho (fat boorish turd...tolerable as a side character, but does not deserve a slot on the roster)
The rest of the MK cast I either love, like, or find 'okay'.
