Rono is another one of Sapphire's main Pokémon during her fieldwork days. As an Aron it loves to chew on pieces of scrap metal, thus saving Mr. Stone's Castform from the water fountain incident. It evolves into a Lairon after Sapphire states that she wants to earn her third gym badge fair and square and battles Wattson. It evolves into an Aggron during Sapphire's training with Ruby and Tate and Liza on Mirage Island.
