I've been back in the Home GTS mines following another rabbit hole and yadda yada yadda i wound up getting a Shiny Tornadus and one glance showed yeah its hacked. The suspiciously perfect spread, the flawless IVs, Level 100, shiny, the filled in marks that PK Hexers love to use, etc. OT literally ShinyDen.Com which I'm guessing is one of the goto generators
But the thing I found funny was the disparity between what is displayed in Home Mobile vs Switch
So in Mobile it says its ina Pokeball, has the SWSH origin mark, and was met in the Galar Region. But also the only game this thing has actually "touched" is SV so you can't switch modes at all.
But in Switch, if viewed while opening a SWSH file, this thing falls apart entirely. It's in a Love Ball with the Legends Mark and met in the Hisui region.
But wait there's more! If you go back into Home View or SV View, it now displays the Love Ball properly & brings back the SWSH mark/Galar Region origin
And I've just gotta know, maybe from someone who has dabbled in this stuff, how you mess up a Pokemon so bad it desynchs like this.
e: Even better, went back into Mobile to double check someting and actually Tornadus is displaying no ball at all there. The Pokeball was there as the default to display for the GTS animation.
e2: Alas, now that it touched Sword (was curious hwat the screens would say), the incongruity caught up to Home and now I can't trade it anymore. Still doesnt display a Pokeball, probably because it now properly displays the Legends mark but Legends doesnt have Love Balls.
e3: I GOT A SECOND ONE
From the same dang ShinyDen!
This one had the same problems, but was Therian form! But, out of curiosity, I tried trading it and it actually worked. Iguess so long as the game doesnt go "wait.....this doesnt make sense at all!" by touching another game it just goes through.
So lesson learned really is just keep your head down and keep pushing it around to other people
Funny thing is through different GTS trades I managed to get a another shiny Tornadus which...also might be hacked but like competently. Originates from Gen 6 (and has proper moveset data for Bank, SWSH & SV so its been around), has the proper location for Hoenn in the Sky, has a ball (Pokeball), seemingly normal stats (random Sp Atk, Def & HP IVs, perfect Atk/Sp Def/Spdd).... but I have to question the fact its still Level 50 despite having 3 Hall of Fame ribbons (XY, ORAS, Alola).
Whatever dude after the last 2 blunders I at least appreciate someone put in the proper effort to appear legit.
