Rusta is a character from The Legend of Zelda: Skyward Sword. A resident of Skyloft, he is an elderly man that often spends his time at the Lumpy Pumpkin. Rusta claims to have seen a monster in Skyloft at night, but no one seems to believe him. However, after Kukiel goes missing, Rusta will tell Link about the monster he saw and how it entered its lair, correctly leading Link to Batreaux. According to Fi, he is also the husband of Henya, the lunch lady of the Knight Academy.
As many residents of Skyloft seem to be named after birds, it is possible that Rusta is named after the rooster. This is also supported by the fact that his wife's name is Henya.
