Fenrir
A legendary wolf-like creature who's been around for over a thousand years. Fenrir has the kind of power most monsters dream of—extraordinary strength, agility, and magic that let him obliterate pretty much anything that gets in his way without breaking a sweat.
That said, he's not exactly humble about it. Fenrir is vain, prideful, and openly selfish. He follows Mukohda purely because the food is incredible, which fans often note is hilarious given his godlike status. He's basically a thousand-year-old legendary being reduced to a familiar for the sake of good meals.
His tastes are predictable: he's obsessed with meat and absolutely despises vegetables. He's gluttonous to a fault, which makes sense when you consider how much raw power he's burning through. The contrast between his immense strength and his transparent food motivation is part of what makes him memorable.
