Why can't I transfer my Trainerfly'd articuno?

Question

I caught an articuno via trainerfly in pokemom yellow. I tried to transfer it to Pokemon bank so I could have it in sun, but for some reason, when I go to transfer it, it says that it can't be transferred. This is weird because I don't have this problem with any other Pokemon that I caught via trainerfly. Does anyone know why this is happening?

Comments

Can you specify more info about this Articuno?

I know that Bank tries to prevent Pokemon caught via glitches from being transferred. Maybe your other Pokemon were able to trick the hack checks into thinking they were caught normally, while this one is setting something off. Hard to say for sure.

If it's a level below the usual level that it is caught at then it won't be able to be transferred

Answer 1

• It could be a level below what it is catchable at in the Seafoam Islands. If this is the case, just level it up to the level it is caught at in the Seafoam Islands, and it should be available to transfer.
• It could have moves it usually cannot have. If this is the case, get rid of the moves it usually cannot learn.
• It could have impossible EVs, DVS, or stats, in which case you can't do too much about that.

If none of those possibilities are the case, we can't really figure out what the solution is without more information.
