Are Reshiram and Zekrom shiny locked in Black and White 2?

Asph  on X: Shiny Zekrom in Black 2 is here! As far as I know, this is a first EVER! Shiny lock removed, of course! 5961 SRs. / X

Have they left Zekrom shiny off or am I just unlucky? : r/pokemongo

6] Shiny Reshiram!!! Everyone knows Reshiram > Zekrom :) I took a break from hunting in white 2 but I still wanted the gen 5 vibe. : r/ShinyPokemon

Finally I Got ✨Shiny Zekrom After 15 Raids in #pokemongo
