Topic: Which Pokemon can't you transfer from Black/White to X/Y

So I got Pokemon Bank and Pokemon Transfer today.
I quickly found some Pokemon can't be transferred for some reason. Although its a little on the random side and here's why.

I tried transferring my legit Arceus, Darkrai, Shaymin, Regiice, Registeel, Regirock, Regigigas, Reshiram, Zekrom, Genesect, Giratina, Deoxys, Jirachi, Rayquaza, Groudon, Kyogre, Latios, Latias, Suicune, Entei, and Raikou.

Now real quickly, I legitimately got all of these Pokemon from previous games and over time have moved them from game to game. This was until I moved them into Pokemon Black 1 and couldn't transfer some to Pokemon X/Y because Pokemon Transfer refused to put them into bank.
It would be easier to say which Pokemon did get through rather than didn't so here are the few Pokemon that Pokemon Transfer would move into bank.

Darkrai, Regiice, Registeel, Regirock, Reshiram, Zekrom, and Giratina.

Now I also tried transferring some of my non-legit legendaries which included other Regiice, Registeel, Regirock, Reshiram, and Zekrom, which to my surprise all got through. I was also able to get no non-legit shiny pokemon through that weren't legendaries.
Now that leaves a lot of very legit Pokemon that Transfer refuses to put into bank.... I would accept this if my friend who also has bank couldn't get his legitimate Reshiram to transfer....
When I say non-legit i mean through the means of Action Replay. Most commonly through the Pokemon modifier and shiny codes.

If you have had problems with this as well, please post which Pokemon you were able to transfer into bank and which ones you couldn't because it's really confusing to me why some Pokemon can get through and some can't.

i have the same problem, i tried to send my Arceus (Hall of Origin - Platinum) and Arceus (TRU event) to Pokemon Bank and said they were removed from the transfer list...

1st point: Hall of Origin Arceus is semi-legit since i used AR to get the flute but besides that i caught it like any other legendary...
2nd point: TRU one (Jugdgement, Shadow Force, Roar of Time and Spacial Rend) - This one is 100% legit and was transfered from SoulSilver, doesn't transfer either.

But my Zapdos from FireRed and Moltres from SoulSilver had no problem...sort of

I always create a copy of my pokemon from Gen IV and V with pokecheck in case my saves go bye-bye...the thing is, the originals wouldn't transfer, but the copies (pokecheck always add a premier ribbon when you send them to the game on their site so you cannot clone/hack and GTS them) went 100% OK =S

Also that was the only way i could send:

Reshiram (White 2)
Mew and Deoxys (Emerald)
Giratina, Lugia, Tornadus, Thundurus and Ladorus (Pokemon Dream Radar)
Victini (White)
Meloetta (Spring 2013)
Genesect (Plasma)

Next i'll try my with my Dialga from Sinjoh Ruins and see what happens...

I had no problems moving my legends from other games but it wont let move my shiny garchomp over and ive had that since gen 4

I've transferred over legendaries such as Reshiram, Dialga, Zapdos, Kyroge, Cobalion, Terrakion and Virizion with success..

what the name the site u used

I was able to transfer all of my pokemon without problem, that includes several legit event and legendary pokemon and even a few I'm not 100% sure about their legitimacy I got from the GTS in Diamond, like my shiny deoxys, Celebi and jirachi.

Your pokemon are indeed most likely hacked.

Azure flute was never an item actually released, and so, is a big red flag for the poketransfer.
The other one if you got from a trade could have been pokegenned. Cloning didn't really exsist back in the day and all the codes and such had the wrong PID.
It's also possible pokecheck didn't catch the region the pokemon is from.. IE, your region, if that's the case the character map for the languages will not match.

The rest went through because those are indeed legit.. the dialgia should go through as well since the event itself isn't manipulated and actually is possible with the movie event arceus. (unlike your arceus which has "hall of origin" on it's met page)

Also all pokecheck does is check pokemon for genning which means despite you typing it out on there, that is not exactly what you have, the PID doesn't match and is differently generated, on there it automaticly generates legit PID while yours in-game may not match.

At that time, celebi and jirachi were shiny locked (and still are) so no those are not legit. If you transfered them like the same day pokebank came out then you may have slipped them through since they needed to patch the pokebank the following day after reports of hacked HA pokemon making it through.

Actually, only deoxys is shiny.

I added the others after I posted that comment, and now it does look like I listed them all as shinies

My issue is: I got action replay hacked Pokemons from a friend, and it won't let me send them. I didn't hack them myself, but it still won't let them transfer. What do I do to bypass this?

Don't hack your game.

...also don't bring g back dead threads.
