It's called the "Masuda Method" and it's been around a long time. It's named after Junichi Masuda who wanted to give people a reason to want to connect with players from around the world. If you breed two Pokemon who come from games in different regions (e.g. USA and Japan) then there's an 8x greater chance of producing a shiny offspring. It's still only 1 in 1024 odds, but it's better than the 1 in 8192 odds that you normally have.

yeah i used to breed shiny eevees with that method

Well, I'm not worried about shinies. If I run into one....I MUST HAVE TI! D:

Otherwise, I'm just trying to fill my pokedex and stuff.

I found a shiny Nosepass the other day. ;o; I wanted to cry because of all the shiny Pokemon I could run into... it had to be that one.

not as bad as the shiny wobbuffet i had on emerald

I would only care if the Wobbuffet was a female. The lips on the females weirds me out. haha

soo.. i just found out this pokemon vivilllon has a bunch of different forms. >__> must.. have all colors...

Mine is the modern pattern if anyone has something else and wants to trade >_<;;;

mines the river pattern :(

Here's my X Trainer:

Waaah! I want a River one! Mine is High Plains Pattern. D:

I want both of yours xD mine is the modern patter D:

k ill level up a couple for trading off

ALL YOUR EEVEES IS BELONG TO ME?!

I'd wonder trade them. All of them. Like I do with my hordes of bidoof that I catch.

Sometimes I feel bad about getting something cool for a bidoof....then I put another in on Wonder Trade.

dude dont put ANY more bidoofs on wonder trade, if you keep doing that you are a dick.

i'll go get some scatterbugs to level as well if anyone wants the modern pattern ^^

I've got High Plains as well, which I think is a little weird -- I moved out of the REAL High Plains years ago, before the 3DS ever came out; there are no High Plains anywhere in California but Game Freak set it that way anyway.

As for the "bad egg" stuff -- I SERIOUSLY doubt the "contagious" nature the article seems to mention. It's true that you can't release a bad egg into the wild, so it's possible that a streak of bad luck combined with this fact could eventually fill up your boxes with bad eggs if you wonder trade a LOT, but we're looking at modern software design here. This isn't Red/Blue. The "bad egg" is an error handler (much like Missingno) but I can't imagine it would set off data-corrupting bugs in unrelated parts of code like Missingno did.

@Ashy
Now I must put tons of bidoof up for trade! All the bidoof!

yeah not cool man

I hate it when people catch junk pokemon and put them in the Wonder Trade. I feel like a douche throwing them back in when I get them from other people. I have put a lot of Volt Tackle Pichu's (that I bred) and Female Ivysaurs (that I caught trying to get the hidden ability one) in and I hope that people actually like those. xP

I save my eevees for GTS. Well, every now and again I'll do a wonder trade with one.

But I just lol'd literally. I put a fletchling in wonder trade....got a fletchling XD It was beautiful

Then I traded a bidoof for a fletchling...then a fletchling for a bidoof lol

i normally put my hatched egg pokemon in the wonder trade >w< where im trying to get shiny pokemon and certain genders/stats.

so like starters and then i have put a good number of fossil pokemon out there xD

I put an eevee up for a houndour. If the pokemon only has trades up for a legendary I say screw it and put up an eevee saying I want that pokemon XD

yeah ive got a fair amount of pokemon i want by putting up an eevee or a ditto, remember, japanese people need other region things too :P

I don't care about regions really...I just like the exp bonus from someone else owning it.

i care about regions.. better shiny chances >w>

i trade my vivillons a lot of times for the jap people offering.. D: most people ask for crazy trades!

I do the -wander in circles training- ...is that a green ursaring? IS THAT A SHINY?! I MUST HAZ! -catches- -pets first ever shiny caught- my precious.

lol xD i think my first shiny was a mareep way back like when mareep was in the proper gen (2nd?) its kinda my goal each time to catch one or trade my old one .. so im waiting on the pokemon bank so i can move Candy to my new game :)

My first shiny was a Stunfisk. I'm not sure if it has terrible IVs or what, because it really sucks. I actually like it's shiny too. :/

My last one was a shiny Mienfoo in White 2 i just remembered

The pattern on Vivillion's wings changes in accordance to the region in which it is caught. This is why a Vivillion from a faraway land is more valuable than it might otherwise be.

I've noticed Modern and the elegant patterns are fairly common/unwanted. Everyone I know has Modern and the Elegant is from most of Japan >_<

The modern patter kind of grew on me. Just wish mine had compound eyes.

i like the modern colours 'cause it makes me think of mondrian, lol.

ocean and sun are the prettiest imo ^q^

do you know if you have to evolve it before trading or can i just trade around one of the pre-evos?

The butterfly? I'm not sure, but I'd rather it be evolved when I got it to make sure XD

yeah i think so too

I sold my Pokémon y, I was just super disappointed in it..

why would you even do that?
