Shiny Delta Deino! Need to change nature

Well, I recently got heart swap in my game and wanted to get delta deino from slither forest. So I was soft-resetting for modest… Now what happened was I got a shiny!! But it has quirky nature… So any way to change its nature? Pokepon takes far too long to recharge cri. Help.

Unfortunately I believe pokepon is the only way to change it, but to next time, breed a pokemon with the ability synchronize and desired nature for your encounter. If you put it in front of your party the pokemon you encounter will always have the same nature as it (i personally have a modest espeon and a jolly umbreon i use to hunt pokemon)

That sounds clever actually! Well ill have to deal with my naive hydreigon then lol

do u trade this shiny delta hydreigon?
