You Can Get A Shiny Zygarde From an event.
I have 3 shiny jirachi’s and a shiny victini so we’re the people I traded with hackers?
Shiny Jirachi is obtainable as legitimate, you can check whether you have a legit or a hacked one here: https://www.serebii.net/events/dex/385.shtml
However as far as I know, Victini has never been released as shiny and is shiny locked in games where it is obtainable: https://www.serebii.net/events/dex/494.shtml
Thus making any shiny Victini illegitimate.
