Grover Underwood is a fictional character in Rick Riordans Percy Jackson and the Olympians series. He is a satyr, a mythological Greek being that is half goat and half human. Grover is the satyr who found the demigods Thalia Grace, Nico and Bianca di Angelo, Percy Jackson, Annabeth Chase, and Luke Castellan. He is Percy Jacksons best friend and has an empathy link with him, which means if one of them dies, the other will probably die too. Grover is initially viewed as weak, but he proves himself to be a capable companion by fighting off monsters and saving his friends while working to obtain his searcher’s license in order to find Pan. Grover serves as the voice of compassion and morality that allows Percy to reflect on his actions and pursue justice fairly. At the end of the novel, Grover achieves his goal of obtaining his searcher’s license and goes to look for Pan.
