Leo Valdez

Born as the only son of Hephaestus who has the ability to control and synthesise fire after decades, as well as Esperanza Valdez, Leo did not have an enjoyable childhood to be remembered, to say at least. From Aunt Tia Callida who happened to be Hera, his first encounter with fire and snakes, and the uncontrollable fire he emitted that eventually killed his beloved mother.

Camp Half-Blood is his home, up until today. It was where he spent the most of his teenage days, where the adventures started, and where he grew up to be a flabbergasting demigod, but with depths here and there. But yes, the Happiness Delight tendency is very strong inside him.

At a point, however, after the war ended, Leo moved. Along with some of his friends. For a better future, albeit far away from the beloved home and Olympus. And he succeeded― now he becomes one of the shining stars in a foreign country namely South Korea with a new name to, at least, conceal his identity as the well-known son of Hephaestus (it did not stop people to spoil his identity really, but most of humans are indeed oblivious about the fact), gained height, and gained more popularity than ever that would instantly made Aphrodite's and Apollo's jealous.

But they would not stop Leo Valdez from remembering the way home to his cabin and Bunker 9, and to devote his life to the continuation of the Universe whenever Olympus calls him back.
