For Celebi, it's the Ageto one. You're right.
But i was wondering if it's an hack, because it's a Pal-Parked pkm & there's very few trash bytes... almost not.
And for the others, the shiny pokemon i took a screenshot : Here .
Here, you can see, everything seems valid, there's few "Chained Sync : Valid" and then Type : Hacked Pokemon".
And that's the same thing with the 2 other shiny pokemon i attached here.
What's wrong with those pokemon?
