Lito was an inhabitant of Meridian. He was the descendant of an expedition which became stranded on the planet a millennia ago.
When the crew of the USS Defiant visited the planet in 2371, Lito was playing a ballgame called vajhaq with another boy. He asked Commander Benjamin Sisko if he wanted to join them in the game, but Sisko declined and hold Lito for a moment.
Later, when the inhabitants of Meridian gathered on a place between their buildings, Lito went to the other Meridian boy to say goodbye.
He was, like all other Meridians, both a corporeal and a non-corporeal being. The planet Meridian shifted between our universe and a universe of pure energy. Lito and the rest of the inhabitants appeared for only twelve days in corporeal form and spent sixty years in non-corporeal form. With the help of Jadzia Dax, the period of time was extended to thirty years starting with their next shift. (DS9: "Meridian")
