In Pokemon Black & White, when the player brings a Gen IV Fateful Encounter Celebi transferred up using the Relocator,
and brings it to the GameFreak Building at Castelia City, the lost boy at the lobby will turn out to be a Zorua when spoken to,
and the Zorua will join the player's party.
The player gets to choose which ball to keep the Zorua in.
