What are all the one-time event shiny myths now available with Go/Home connectivity?

Question

Like, I just transferred a shiny Darkrai but Shiny Darkrai was event only once back in the DPPt days. Which other shiny Mythicals that were really only available once are now available?

Comments

I believe they were all available to transfer up from previous games. Like if you got a shiny Darkrai from the event in DPPt then you could have transferred it up when Home was released. Can you get Shiny Victini/Keldeo/Meloetta in Go because those would be the only ones if so

Answer 1

The mythical Pokemon that can be caught today in a main series game without glitches/hacks as shiny are

Celebi (Crystal Virtual Console)
Phione (Breeding)
Shaymin (BDSP Oak's Letter event)
Arceus (BDSP Azure Flute event)
Technically Jirachi and Manaphy, if you have the Colosseum Bonus Disk and Pokemon Ranger, respectively.

Also Mew and Deoxys can be caught shiny if you somehow have a FR/LG/E cart that has these two events still unused on them. Darkrai can also be obtained if you still have the event from back in the day.

Therefore, the Mythical Pokemon that can only be obtained as shiny in Pokemon Go are Genesect and formerly Meltan, but for 99.9% of people, Jirachi, Mew, Deoxys, and Darkrai are also only available shiny in Go. Manaphy cannot be obtained shiny in Pokemon Go.

The other Gen 5 and Gen 6 Mythicals are not obtainable at this time shiny in Go.
