A Centaur

You can't imagine how you didn't see him earlier as the centaur is revealed to you, towering over you as he confidently steps along the sidewalk towards you.

His upper half is completely human, save for his furry pointed ears, with long blonde hair and a handsome face. His arms and chest are quite muscular, pulling his white t-shirt tight as it hugs his well toned torso.

His lower half is completely horse, a well-muscled thoroughbred covered in a thin coat of chestnut fur with a tail that matches the blonde hair on his head.

Giving you a broad smile that exposes his white teeth, he holds his hand up in a quick wave. "Hey there. The name's Buck."

You turn to ask the agent how you're supposed to keep a giant horse man in your house, but as you turn to where she was standing, you see her van pull out and speed down the street, leaving you alone with the grinning centaur.
