Professor Ladon is as described as a dragon-headed figure, and the way he speaks resembles a snake speaking. He makes his book debut in Athena The Proud.


Professor Ladon is a slightly startling teacher than even Athena is scared of, but he doesn't seem to frighten Poseidon as Poseidon is acting like a teacher's pet to please him.
