So, it was previously stated that Zekrom, Reshiram, and Victini COULD NOT be Shiny. When being caught from N's Castle/Dragonspiral Tower, and Liberty Garden.
Now, giveaways for all 3 Pokemon have been released. The Victini with V-Create, Fusion Bolt and Flare, and Searing Shot, the Zekrom with Fusion Bolt, Bolt Strike, Outrage, and Haze, and the Reshiram with Blue Flare, Fusion Flare, Draco Meteor, and Mist. Could these 3 Pokemon now have Shiny counterparts legitimately if you soft reset in front of the delivery person? Or are they programmed not to be Shiny also?
