Frank Zhang A son of Mars - the Roman aspect of Ares - with the ability to transform into any animal. Descendant of Poseidon through the Chinese demigod tradition. His life is literally tied to a piece of firewood. One of the most genuinely kind characters in the Riordanverse. | Son of Mars | Protagonist |
Hazel Levesque A daughter of Pluto - the Roman aspect of Hades - and one of three Roman heroes given the prophecy that opens The Son of Neptune. Quiet, watchful, and carrying a past she rarely talks about, Hazel can sense and control precious metals and gems underground - a gift she finds as much a burden as an advantage. She fights alongside Frank Zhang in the Fifth Cohort at Camp Jupiter. | Daughter of Pluto | Protagonist |
Percy Jackson A son of Poseidon who discovers his divine heritage at age twelve when monsters begin attacking him. Over five books he grows from a confused kid who can breathe underwater into the demigod at the centre of the Great Prophecy. His fatal flaw is excessive personal loyalty - he would risk the world to save the people he loves. Continues as a major character through Heroes of Olympus and appears in later series. | Seaweed Brain, The Son of Poseidon | Protagonist |
Nico di Angelo A son of Hades who first appears as a cheerful ten-year-old obsessed with a card game and becomes one of the most powerful and isolated characters in the series. His arc across both the PJO and HoO series is about surviving grief, accepting his sexuality, and finding that belonging is possible even for someone who lives between worlds. | Ghost King, Son of Hades | Major |
Reyna Avila Ramírez-Arellano Praetor of Camp Jupiter and one of the most capable leaders in the series. Daughter of Bellona, Roman goddess of war. Her arc in Blood of Olympus is one of the series' best subplots. | Reyna, Praetor of Camp Jupiter | Major |
