Why can you play as a girl in Pokémon Crystal?

Pokémon Crystal, released in Japan on December 14, 2000, is the first Pokémon game that asks who the player is. At the start, the player chooses between a boy, Ethan, and a girl, Kris, making Crystal the first time in the series that players could choose their character's gender. The game's own box carried the line: for the first time, play as a male or female trainer.

The choice is purely aesthetic. Kris's journey through Johto and Kanto is identical to Ethan's in story, battles and destinations; what changed was representation, in a series whose audience had never been only boys and whose games had simply never offered the option.

It is one of Crystal's cluster of firsts, alongside animated sprites and the Battle Tower, and it became permanent: every core game since has opened with the same choice, making Crystal the moment the series' default hero stopped being a single fixed boy.

For collectors, Kris is also a piece of box history: her debut is printed right on the packaging, one of the rare times a Pokémon cover advertised a social change as a feature.
