So Benzin is Diesel's mother, and this is Fontain, Deisel's father. Like Diesel his form can shift slightly, meaning his wings can embed themselves into his side, showing as jagged markings along his back, and that Yin-yang fades when he's well rested. Being white is a conscious decision, all the black contained to the stripe on his head, but when he's tired his darker fur color "bleeds" back into his appearance.
