So! This is Kass: mighty werewolf, total softy, pie eating champion. You’ll notice the pigeon sitting on their head - that’s Boško, the familiar of Kass’s witch girlfriend Mila. He's a checkered patterned pigeon and a little sassy bastard. Like most familiars, he enjoys being cryptic and stirring up trouble.
I made this character sheet a while ago, and more recently posted a clearer reference sheet here: https://www.furaffinity.net/view/44375631

For those wondering, the angry werewolf that has Kass pinned is their father, Cyrus, and the artwork that lineart is from is here, along with a very brief explanation of Kass's scars.
