What Pokemon can not be legitimately caught shiny?

Question

like zekrom reshiram

Answer 1

Okay, bulbapedia specifically names Victini, Zekrom, and Reshiram as not being able to be shiny. However, it says that wild Zekrom, Reshiram, and Victini can't be shiny, which means that they might be shiny when obtained through instant gain events.

The only two event Victini's were never shiny.

Answer 2

As of Generation 8, the following Pokemon cannot be shiny:

Any Ash-hat Pikachu (technically can be, but coloration does not change. Credit to Y for that one)
Victini
Keldeo
Meloetta
Vivillon Fancy and Vivillon Pokeball patterns
Hoopa
Volcanion
Cosmog
Cosmoem
Magearna and Magearna Original Colour
Marshadow
Zacian
Zamazenta
Eternatus
Kubfu
Urshifu
Zarude

The Galar starters are also only obtainable as shinies by breeding -- you cannot sort reset at the start of the game for them.

There are more, which can be found in my source.

Serebii seems to say that Ash Hats can't be shiny at all. What's your source on that?

"Due to a bug, this Pikachu can be Shiny. Instead of checking its personality value against the Trainer ID and secret ID number of Pikachu's Original Trainer to prevent its personality value from making it Shiny, the game uses the player's data instead. Shiny Partner Cap Pikachu are identical in appearance to normal ones."
