Togetic, Johto's happiness Pokémon, can be found in the wild in Pokémon Go. Yes, Togetic can shine in Pokémon Go!
Togekiss is a great fairy-type attacker, as it has bulk and a decent moveset. It's also used in PvP, meaning taking a ton of Togetic to check your IVs is a worthwhile effort.
What is Togetic's shine rate in Pokémon Go?
According to old research by the now-defunct website The Silph Road (via Wayback Machine), the shine rate of Pokémon on a typical day is about one in 500. Togetic is not a confirmed Pokémon to get a “permanent boost.” ” (meaning it is a rare spawn and therefore gets an improved shine rate).
What can I do to attract more shiny Pokémon?
Unfortunately, not much. It seems to be a coincidence. Shiny Pokémon catch rates are set by developer Niantic and usually only increase during special events like Community Days or Safari Zones, or in legendary raids. There are no consumable items that increase Shiny Pokémon rates.
