RE: The B/W Questions and Answers Thread
@Tyrant Tyranitar: Unfortunately Victini's got a shiny check too, despite the operations of those past events, the same coding tag as Reshiram and Zekrom in fact. Game Freak's decision at this point seems kind of arbitrary, as the only practical repercussion this has on these particular Pokémon is a reorganization of natures, which still remain random, so the it's hardly observable in normal gameplay. With events however, shiny checks are noticeable because they're used to give Pokémon constant natures, genders, and abilities, which serves a practical use for designing the specs of an event Pokémon. Victini in particular however isn't within technical boundaries a true "event" Pokémon – it's simply a normal wild Pokémon that can't be accessed without the game/code alterations/unlocking caused by the use of the Liberty Ticket, so as far as I know there wasn't a practical reason to give Victini a shiny check either in addition to Reshiram and Zekrom. Perhaps it's to give more importance to future events for shiny version of these Pokémon, though with what we know about the games right now that seems to me a bit far-fecthed. Otherwise maybe it's just trollin', haha.
