I know that, since the beggining of Mortal Kombat, the ideas of ninjas was taking different forms. Even so, everyone will see Sub-Zero and Scorpion as ninjas. They have a clan, a martial art learned, principles, etc. But with the changing of the games, many playable characters, that could be ninjas, would morphed into warriors, but no necesary ninjas.
I ask do you think these characters are ninjas:
Kitana
Jade (both have skills like ninja, and Jade has her pole)
Mileena (like before, she has her Sais)
Ermac (in the beginning, he was dressed as a ninja, but in the new continuity, he doesn't seem like before)
Rain (same as Ermac, he is far from a ninja style nowadays)
Shujinko (he has trained in many arts and styles)
Reptile (he is dresed like, but his fight style doesn't fit)
Sektor
Cyrax (when they transformed into robots, the technology suplanted their skills)
Shang Tsung (maybe, like Shujinko, he traveled and learned about martial arts)
Kobra (maybe more like karateka)
Tremor

Just want to see what's your opinion about, and if you think another character with ninja style.
