Who the fuck is Cole?
I know a surprising amount of mortal kombat mythos, the o.g. subzero died in MK 1, you would know this if you read the damn manual! His younger brother returned in MK 2 but looked exactly like the original, then they took his mask away in MK3, which is where I stopped caring so much because I never liked the predator dreadlock robots, and where the fuck was Scorpion?!?!?
Anyway o.g. subzero is resurrected as Tobias Bo...er Noob Saibot. Sub Zero in MK1 is a baddie, in MK2+ Sub Zero is good. O.G. Sub Zero murdered Scorpion's people, so Scorpion, now resurrected as an undead revenant of Hell (hence his teleport, and skull fatality) , wants to kill him (something something it was Quan Chi pulling the strings)
