Buck's a tall, smarmy looking... thing. He's covered head to toe in soft crisp white fur, which bleach-white skin underneath. It's hard to tell what's furry and what's not. Despite his grey mullet, he's well built and pretty hot. His face is oddly proportioned, but not grotesquely. He has a huge chin sporting a smart grey goatee which flares out into long sweeping sideburns. His eyes are narrow and squinty, but they twinkle with energy. He has a short, blunt upturned muzzle. He looks a bit like how a cartoonist would draw a bulldog (minus the jowls), only if you ask him, he'll assure you he's a wolf.
He doesn't have a tail, though.
His suit is a marvel in and of itself. Besides looking very sharp itself (tiger-striped with shiny and dull red fabric with bright yellow lapels and cuffs), the pockets are a lot bigger inside than they look on the outside. It cleans itself, too. It looks very very expensive. Or would, if he had bought it with money.
Not much is known where Buck comes from. He lives the high life of the amnesiac.
He's the brain and heart and muscle and dick behind Interpron Studios, too.
Among his powers are looking good in a mullet.
He also has a bad habit of dying. Though he's really hoping it won't become his schtick.
