Centaur

Centaurs are from Greek mythology.

Horse/Man
Centaurs are half horse half man. They have the body of a muscled, strong, naked man, and the bottom of a fast running horse. They live in the woods, too. They are also really hard to sneak up on.

Deadly Mythes of Centaurs
Their are many scary mythes of centaurs. In Percey Jackson there is a centaur. Many stories include centaurs. You can get some names from reading this:

Chiron

Eurytion

Pholus

Nessus

Rhoecus

and

Hylaeus

So, as I was saying, there are lots of Centaurs out there. Maybe, you too, can learn more.
