Ruru was the third of the main Pokémon that Ruby had with him during his move from Johto, it used to specialize in Smart Contests before it was replaced by Fofo after being lent to Wally. As a Ralts, it also possesses great power as it was able to lift the moving truck that Ruby was in with its Psychic powers after it got stuck in the mud during his move to Littleroot. It was later lent to Wally when he was asked to go with him to catch his first Pokémon. It was never returned after a long time since Ruby got washed away from a tsunami. It evolves into Kirlia during its stay with Wally and later evolves again into a Gardevoir during its training with Sapphire and her Gallade.
- In the Chuang Yi translation, Rara was known as Ruru.
