so yeah, this idea as be rolling around in my head for a while and went through several designs before I did one that I was satisfied with. I made it so aku aku actually fits on crash's face like a mask instead of just being placed on his nose like in the games and glowing tribal tattoos appear halfway down crash's body when he puts aku aku on his face.

and I designed a spear of crash to have has a weapon, basically the backtory behind the spear that is has mystical powers and once belonged to aku aku when he was human and given to him as a gift by aku aku.
