Could've sworn GAME FREAK bunked that, saying Phione was Legendary (and Rotom was not).

Still, Phione's not as big a name as Manaphy, so it's hardly surprising... There are already plenty of Legendary bosses as it is; I'd be glad just seeing it running around.

Also, @Serebii, I wasn't aware there was a different Browser for Past Pokemon.... That really explains a bit. Certainly looking forward to seeing that one.
