From its earliest depictions, Latias has always been described as female – a term applied extremely rarely to the pokemon called gods. And legends repeat that at times in her eternal life, she has taken human form, coupled with men, and reproduced. This was said to be the only way she could have children, for Latios, her only male counterpart, is her brother.
The first King of Hoenn was claimed to be the son of a legendary hero and Latias in human form – a claim always disputed by his rivals. Despite the efforts of official censorship, this was an era when most people bred their own pokemon for agricultural use, and knew full well that female pokemon gave birth to pokemon in the same evolutionary line. If Latias was crossed with a human, they claimed she would produce another Latias, or perhaps a Blaziken – for like Manaphy give birth only to Phione, so too would Latias refuse to relinquish her uniqueness and spread the powers of the gods too widely.
Yet this claim about coupling with Latias has been echoed in every age by the greatest of conquerors and trainers. Ordinary people can not even approach Latias; those who seek to chase her down will never come any closer than a flash of red and white across the sky. Yet when anyone living is found worthy by Latias, the descriptions agree she will race around the world until she meets them, take the form of a beautiful woman, and try to win their heart.
Latias still waits for a boy from Pallet Town to finish his pokemon journey and return to her side, and treasures the memories of the time she shared with him in Alto Mare City like nothing else in over a thousand years.
