In the book we meet Leo a trickster kid who is the best of friend of the main character. The first time we hear of him in the book is when it states, "I didn't steal that car Leo"(Riorden 5). This was first mentioned when Piper, another main character, is complaining about a story that Leo is telling Jason. She yells his name while she's complaining.
Leo is described as being Hispanic, short, and having black hair. This is supported by the phrase, "He looked like a Hispanic Santa's elf"(Riorden 5). This is Jason's way of describing Leo and how we will identify him for the rest of the book.
Leo is portrayed as being a jokester who never takes things seriously. He always makes fun of his surroundings supported in the text by, "You want us to ride off to save the world on happy the dragon"(Riorden 188). This is one of many jokes made in the book that supports Leos joking attitude.
Leo in the beginning of the book would sometimes be useless and lacked powers supported by his need to be rescued. An example of this is during the fight with the Storm Spirit everyone is preparing for battle while Leo is getting thorwn around by the wind.
Later in the book Leo becomes more curageous after he surpasses his first task and defeats the cyclops. This is the first fight in the book that shows how Leo is curageous as he fights off the monster supported in the text by, "Heck yeah I got tricks. Leo raised his remote control. Take one more step and I'll destroy you with fire"(Riorden 266). Leo confidently shouts out to a monster telling them that he will destroy them proudly and and with confidence in his ability.
Further in the book Leo becomes a less confident person who get a raw deal compared to the other main characters supported by, " Leo figured he had the worst luck"(Riorden 384). In the book Jason and Piper get strong powers and weapons and all Leo gets is small fire power and a dragon that breaks down and dies half way through. These are early examples of the raw deal that we seam to notice more of later in the book.
