List of Percy Jackson and the Olympians characters
Grover Underwood: He is a satyr and Percy Jackson's best friend. He has found the four most powerful demigods of the century (children of the Big Three): Percy Jackson (son of Poseidon), Thalia Grace (daughter of Zeus), and Nico and Bianca di Angelo (children of Hades). Before his death, Pan (the god of the wild) proclaims Grover as the bravest satyr and names Grover as his successor to carry on his word to protect the wilderness. The Council of Cloven Elders is angered by this choice. He is the boyfriend of tree nymph Juniper.
