Sonic looking pretty damn fierce in his werehog form.

I find it quite an appealing design, it looks quite fierce and feral , but not too scary-looking to be unfitting Sonic form, the exaggerated physique and great fluffiness take care of that.

While the inspiration from lycanthropy is obvious, the werehog form takes traits from Dark Gaia creatures first and foremost, particularly nightmares, sharing top-heavy body structure as well as strength and stretch-related powers.

More superficial wolf-ish traits help retain Sonic’s mammalian appearance while making him look fiercer, instead of the nightmare’s fish-like jaws and smooth glowing skin.

I love the detail in Night of the werehog. On the last photo,you can see the veins in his eye.
