Are you 100% sure on that?

I know from first hand experience that you can't. A friend of mine gave me a hacked shiny Deoxys, and it didn't transfer.

Put up a Feebas for a Virizion a while back. It didn't push, but I didn't really have much else to do so I left it.
Went to the GTS to look for Raikou again, and, lo and behold, I got a Korean Virizion for that Feebas.
I'm so angry...I can get the bird trio, Virizion, a Spanish Palkia. But Raikou is suddenly the Pokemon gold mine?

Do you need Raikou just for Dex data? because I can get you both normal and shiny if you want.

Why do i have 3 shiny Suicune's?

That would be quite nice, please.

I have two. They're everywhere thanks to being given away a few years ago.

Matrix, when you get the forces of nature from Dream Radar, can you let me know what level they're at? I'm a little curious about that because of the frequency of level 5's I see for those three on the GTS that just do not seem right...

Their levels are dependent on the game they're transferred to, connected the amount of badges that game has.

So if you have no badges, they're at level 5, but if you have all 8, like I do, they're at 40.

Oh.

That's really freaking weird.

But it means those are probably legit then... and I could remove the stipulation that the Landorus I want be "61-70" (being 70 in B/W), huh?

Yeah. You can get legit Lv 5 Landorus.
