My name is Legion, for we are many.
Since this thread is about images, art, and visual stimuli, I'm going to ask: Why do the Jackals look so different in every Halo game? Of course it could be simply artistic license or graphical overhaul, but every other species is instantly recognizable as itself from one Halo game to another.
In Halo CE the Jackals were large doglike creatures with flat teeth and jewel eyes. In Halo 2 they took on a velociraptor-like reptile look with distinctive smooth, orange skin and glowing pink eyes. Then in Halo 3 they became barefoot, had black sharp claws, and had mottled, calloused, tan brown skin; their eyes also became larger and rounder. In Halo Wars they had yellow skin and matching eyes. After that in Halo Reach their spiny feathers became black and blue, their claws became ivory-colored, and their eyes became pearly and translucent.
Not that I have anything against Halo, but I'm kind of confused as to why the developers would change the Jackals' appearance so much between every Halo title.
