Latias

Latias is a Dragon/Psychic-type Legendary Pokémon who first appeared in Pokémon Ruby and Sapphire Versions. She is the female counterpart of Latios. Latias has hefty statistics and a wide movepool (including the trademark Mist Ball attack). Latias' stats are more on offense for defense.

Pokémon Ruby and Sapphire Versions
In Pokémon Sapphire Version, after the player has beaten the Elite Four, he or she will return to the house. When the player walks downstairs, the player will see an announcement that a red Pokémon has been spotted soaring the skies. Latias will then appear anywhere in Hoenn except caves. It runs away after every encounter, similar to Entei, Suicune and Raikou of Pokémon Gold and Silver and Pokemon FireRed and LeafGreen Versions. It moves in a pattern around Hoenn, and can be tracked on the Pokédex. Using Fly will make Latias move far from her point at that moment.

In Pokémon Ruby Version, Latias does not appear during normal gameplay. However, if the player uses the Eon Ticket, he or she can travel to Southern Island, where they can find a Latias, who is holding a Soul Dew. It does not run away.

Pokémon Emerald Version
In Pokémon Emerald Version, after beating the Elite Four, a television mentions a flying Pokémon, but the colour is masked by a burst of static. The colour is not heard, so the mother asks the player what colour it was. If the player says red, Latias will be the Pokémon wandering around Hoenn. If the player says blue, Latios will be the Pokémon wandering around Hoenn.

Pokémon Channel
In Pokémon Channel Latias can be found at Cobalt Coast under certain time and weather conditions.

Pokémon Mystery Dungeon: Red Rescue Team / Blue Rescue Team
In Pokémon Mystery Dungeon, Latias and her brother Latios will join your rescue team after you rescue her from floor 25 of the Pitfall Valley dungeon. She is at level 28.

Pokémon anime
Latias and her brother Latios appeared in the fifth Pokémon movie, Pokémon Heroes, as guardians of the Venice-like city of Altomare. At the end of the movie, a Latias and two Latios (with no confirmed connection to any seen or mentioned earlier in the movie) are seen flying toward Altomare. She also is Ash Ketchum's friend, or speculated girlfriend, as they hugged after saving Latios from the machine that imprisoned him, as well as the fact that she may have kissed and given him a drawing of Ash and Pikachu as they departed on the boat, shocking Misty and Brock. This is a point of speculation because in the movie it was Bianca's form that kissed Ash. Most fans argue that it was Latias in Bianca's form, which is Latias's choice of disguise when traveling around in human form, as Latias very much appears to be falling in love with Ash from her behavior to him all through the movie. Also, this Bianca was not wearing her hat, a feature that differentiated the two; Bianca always wears a hat, while Latias in disguise does not.

Pokémon Trading Card Game
Latias has made some appearances in the Pokémon Trading Card Game.

EX Dragon Frontiers as EX delta species fire-type
 * EX Dragon, as Latias ex, a Colorless-type Pokémon-ex
 * EX Deoxys, as Latias-*, a Colorless-type Pokémon-*
 * EX Delta Species, as Latias, a Steel/Lightning Dual-type Delta Species Pokémon
 * EX Holon Phantoms (twice), both as Latias, both Fire-type Delta Species Pokémon

EX Trainer Kit as Colorless-type Basic Pokemon, along with Latios.

A Latias or Latios card came packaged with the Pokémon Heroes movie.

The released Latias cards have more potential to do damage than the Latios cards. Still, they are equipped with interesting effects such as healing powers that benefit your Pokémon rather than focusing fire on your opponent's.

Latias stars as a Pokémon-ex in the final third-generation set, EX Dragon Frontiers, alongside other Pokémon-ex dragons including Latios, Salamence and Flygon.

Etymology
Latias' name might have been derived from the Latin word latere (as in latent), which means to lie hidden or to be invisible. The a in her name may also be a nod to her gender, just as a is often used in the feminine versions of nouns in some.

Physical appearance
Latias is a red-and-white dragon with small arms and feet, and spiky wings on her back. Her design appears to be inspired by the classical shape of a jumbo jet airliner. She is covered with loads of very small feathers made to look smooth by glass-like coats of shiny down. She has triangle-shaped blue markings on her belly that are similar to those of a Togepi. This triangle's color is in direct corelation to Latios' main color. For example, if the Latias has a different color scheme, known as being 'Shiny', her triangle is turquoise rather than blue, because a 'Shiny' Latios is turquoise.The color of Latias shiny body is a metallic orange/gold. Latias is able to alter her appearances with this coat by enfolding her body with her down and refracting light in unique ways. In this way, she can seemingly transform into a human or animal, or render herself invisible.

Personality
Latias is highly sensitive to the emotions of people and can telepathically communicate with them. If Latias senses any hostility, she ruffles the feathers all over her body and cries shrilly to intimidate her foe. She therefore rarely makes contact with people or other Pokémon. She often disappears if she senses hostility as described above. Like her kin, Latios, Latias is also highly intelligent. Latias have been occasionally sighted in small herds of several members.
