nope.
those other ninja do not belong to the lin kuei clan from which sub
zero came from.
the other ninjas were mainly ermac,rain,reptile,khameleon..
scorpion was from a rival clan to the lin kuei, he got killed by
the sub zero in mk1. on a mission, and thus his clan was wiped
out.
the scorpion which is a living wraith den killed sub zero, which
later became noob saibot..
the sub zero u see now is his younger brother.
most of the other lin kuei ninjas became robots like smoke,sektor
and cyrax..
i know its confusing but nvm.
