Noob wasn't missing from a previous tournament.....

He wasn't in the first tournament and basically stayed in the shadows of the second tournament just as an observer. The secret boss battle during MK 2 may or may not be canon. Just depends on how you look at it (it takes place in Goro's lair which is on Shang Tsung's island that sank into the lost sea after the first tournament).

Then if he wasn't in the first two tournaments he wouldn't have been missing. It says he has long been missing from a previous tournament....if MK3 was his first then that doesn't work.

The way I interpret that is they mean it's his original identity (Sub-Zero) that has been missing since the first tournament after his death but now he has returned, in a new form (which no one knows that at the time).

But looks like we'll go round and round about this point so oh well.

Why are there two Sub-Zeros in UMK3?

Geez.

and if classic Sub is noob... and who saw Noob without the mask? then how you can dicede the cassic sub is noob... the ending says that then he removes his mask they see fighter whos been missing from the preveous mk.... at this point you can say that classic sub is sub from the mk1 but you can't say that he is noob becouse you didn't saw noob withot mask

Honestly, I have no idea, but i guess its to make the game better. Stuff like that has confused me for a long time, and to this day, i still don't know. It makes for a good thing for some one to find out, though!!!
