Alleyway Jack is human?
GOD you just can't ask four handed people if they are humans.
I think he's relatively human, he's got a human skin tone.
(SPOILER)And besides, he's really Gilgamesh
It's not like there is a whole race of four handed people in FFIX so there is really nowhere else to fit for him.
I can't really argue it. For some reason though I had imagined him as a four-armed Cleyra/Burmecia rat-person instead of normal human.
And (SPOILER)him being Gilgamesh doesn't really support either side, since it's not clear what manner of being Gilgamesh is...
1) (SPOILER) Yep you guessed it... double spoiler...is it Iron-Tail Fratley?
