Hi my name is Damound and I am going to tell you some facts about Cerberus. Did you know that Cerberus has 3 heads? He guards the Underworld. Cerberus also is really big. It's about 900 ft. tall. Its predators are the Hydra which has 7 or 9 heads. It is also very big. It's about the same size.

The Cerberus weighs about 20,000 lb. The Hydra is about 10,000 pounds. If they fight the Cerberus will win and kill the Hydra.
I think that the Cerberus is the best Mythological monster!
