KYLE'S BACKGROUND COUNTRY IS EGYPT

Things to prove this theory:

-Kyle has strange markings on his face and arms, which I'm pretty sure is facepaint or makeup. Both men and women in ancient Egypt wore makeup. Wearing this dark makeup around their eyes could have been a way to shield their eyes from the bright sun because it helped deflect the glare away.

-Kyle wears a jackal mask. The ancient Egyptians used to worship the god Anubis, the Egyptian god of the dead. Anubis was also the god who watched over the process of mummifying people when they died. Priests often wore a mask of Anubis during mummification ceremonies. Anubis is impatient and impulsive. As a god and an immortal, he sees himself as being above the mortals around him. He has adapted less well to working on earth than the other gods. He is also a bit lazy and expects others to do the work for him. This is very similar to Kyle's personality. Anubis had the head of a jackal and the body of a human.

-I mentioned this before in Theory number 1 but it's still important. The main language of Egypt is Arabic. In Arabic, Hakim (Kyle's surname) has two meanings. The first one is Sage. The Sage has two meanings. The first one is an aromatic plant whose greyish-green leaves are used as a culinary herb, native to southern Europe and the Mediterranean. The second one is either of two bushy North American plants with silvery-grey leaves (I copied Google.) The second Arabic definition of hakim is wise.
