Questions about the oras Shiny Rayquaza Distribution?

Question

I just received the Mystery Gift shiny Rayquaza, and it came with Bashful nature. It's characteristic also implies that it has higher speed IVs. I was wondering if it always comes with Bashful nature, and if it has a set amount of IVs.

Also, what's with Galileo? (OT) Like, is that a joke?

Answer 1

No, I was able to soft-reset for an Adamant natured Rayquaza. When I was soft-resetting, each Rayquaza would have different IVs, but all of them had a minimum of three perfect IVs, in line with other event Pokémon.

As for Galileo, he was an astronomer and it could be a reference to how Rayquaza goes with you to space to defeat/capture Deoxys.
