Kiri and Ankha are the lesbian Saurians, right? Yeah, they were in Conquest, not DOTR.
Takeda was first mentioned in Mythologies, before they used that name for a character in Conquest. He was described as a Lin Kuei who quit, moved to Japan, and stole their fighting style to become the inventor of Ninjutsu and founder of Scorpion's clan.
Cyber-Hydro was MK: Legacy. So "MKL", not "MKC".
And it's spelled "Kunoichi", with a U.
Also, Tanya's never worn a mask or been an assassin, so I don't think she counts as a ninja.
And you forgot Wu Lae, the orange ninja from the Tengu clan in MK Armageddon.

Thank you RazorsEdge, I have fixed what you noticed. I do think Tanya is a Kunoichi because of the fact that Khameleon has one of her moves in MKA and Tanya wears a outfit similar in design to other kunoichi.

I think it's just the color scheme that classifies her as a 'ninja.'

But yeah, she's never wore mask, so she's like the outsider here.

Scorpion is really the only in ninja in the game anyway, so I guess it's all in good fun.

Eh...I guess that's a logical enough reason. I don't necessarily agree still, I don't think Khameleon should've had that move in the first place...but I'll let it go.
