List of Characters in The Percy Jackson and The Olympians Series and In The Heroes of Olympus Series - Main Characters - Leo Valdez

Leo Valdez

Leo Valdez is a 15-year-old demigod, a son of Hephaestus. He befriends Jason at the "Wilderness School", although it is later revealed that everything that happened prior to the Grand Canyon museum trip was actually a trick of the Mist, a supernatural force that actively attempts to hide the mythical world from mortals (and sometimes demigods) by changing how mortals perceive and remember events. Leo also has the ability to touch and produce fire, a skill that no son of Hephaestus has had in 400 years. He is also an excellent mechanic due to his father's abilities and has experience working with machines, as his mother was a mechanic. In The Lost Hero, he discovers a secret bunker hidden in the forest near camp, which contains a magic tool belt that grants him almost anything he wants, including breath mints. He uses the bunker and tool belt to repair a bronze dragon that was previously running wild in the camp's woods, naming it Festus after his initial mispronunciation of his father's name. Leo is a joker who cannot keep his hands still, and he tends to fall quickly for girls. In The Mark Of Athena it is hinted he might have feelings for Hazel Levesque.

In The Son of Neptune, Hazel Levesque discovers that Leo resembles her former boyfriend, Sammy Valdez. She suspects Sammy may be an ancestor of Leo's, which is discovered to be true; Hazel and Leo figure out that Sammy Valdez is Leo's great-grandfather in The Mark of Athena.

Leo is described as looking like a "Latino Santa's Elf" with curly black hair, dark brown eyes, pointy ears, a cheerful face, and a mischievous smile. He is described as being short with a slim build.
