Ralts is a humanoid Pokémon with a white body. It has thin arms and legs that widen toward the feet. There is a wispy extension trailing off the back of its feet, creating the overall impression of a nightgown or oversized dress. Most of its face is covered by green hair that resembles a bowl cut, but a pair of pinkish red eyes is sometimes visible. There are two flat, red horns on top of its head: a large one toward the front and a smaller one at the back.
Ralts uses the horns to read people and Pokémon's emotions. Warm feelings cause its body to warm as well, but it hides if it senses hostility. If its Trainer is in a cheerful mood, Ralts also becomes cheerful and joyous. It is known to inhabit urban areas, but it does not normally show itself to humans. However, when it senses happy feelings, it will approach people.
Ralts debuted in Do I Hear a Ralts?. Max found one that was very sick and decided to prove his abilities by taking responsibility for it. With the help of Snorunt, he rushed it to the nearest Pokémon Center. He later promised to return for Ralts when he became eligible to be a Trainer.
Ralts, the Feeling Pokémon. Ralts is the pre-evolved form of Kirlia. It can use the horns on its head to read human emotions. Ralts rarely shows itself to humans, but may occasionally approach when it senses positive or happy feelings.
This concludes the entries from the Advanced Generation series.
Ralts's Pokémon Trozei! sprite is the only one where its eyes are visible. In Pokémon X and Y, Pokémon Colosseum and Pokémon XD: Gale of Darkness, one can see them if one were to view Ralts from below in the Pokédex/Trainer memo; however, it is not a sprite.
Ralts is the only Pokémon with a base stat total of 198.
This is also the lowest base stat total of all Psychic-type Pokémon.
Despite the fact that Wally catches his Ralts on Route 102 at level 5 in the Hoenn games, it is impossible for the player to catch a level 5 Ralts in the entire game, except through the DexNavORAS.
Ralts's appearance seems to be based slightly on that of a young child, following the theory that young children can sense feelings easier and more thoroughly than adults. Its red "horns" also resemble the tips of a heart shape.
Ralts may be a partial anagram of astral (as in astral body); its other language names seem to follow this. It may also involve relate, referring to the way Ralts will only relate to kind Trainers. It may also be a play on waltz (a type of dance); Ralts' evolutionary family appears to have several similarities to dancers.
