@Sabresite I've already uploaded the shiny one here too ><
@Deoxyz agreed. It's time to unlock every shiny! At least this beast that has been locked for the longest of time, finally gets to see the light of day!
@wo0ts the "fateful encounter" flag isn't data that belongs to Gen 1 And Gen 2 data structure. So any Mew or Celebi that manages to pass PokeTransporter from those gens will get it!
I'm so glad it's confirmed they didn't bother to shiny-lock it. It makes Crystal well worth of a VC re-release, and not as much of a cash grab. I'm not too big on transferring, I prefer keeping pokemon in their origin generation. Though I'll definitely transfer a second shiny Celebi to my current-Gen shiny mythical/legend collection.
I hope the other unobtainable shiny mythicals become available soon. At least we can expect the Alola legends won't be shiny-locked when we get them in Gen VIII.
