6th Gen All the legends have shiny checks?

[Z25]

I am wondering do all the legends in this game have shiny checks? I haven't seen anyone get their shiny forms. Has anyone seen pictures of them? If so could you post them here. If they are shiny checked why do you think they would do that?

In Pokemon Black and White two it was impossible to catch some shiny legendary. I assume it's same with X and Y.

I noticed that Yvetal was very easy to catch in my game. I also read someone say they caught it easily...so I'm assuming the mascots of these games have low catchrates like the BW one's...

Now I think that GF plans to release a shiny version of the Tao trio eventually...I expected it to happen during Gen V...but we didn't get anything (ironically it was the Creation trio...aka as the other Dragon trio). Same could apply to the XYZ trio.

I was under the impression someone caught a shiny Xerneas?

Although I heard Zygarde can't be gotten as a shiny.

I saw that pic also. It seems photoshoped, the person provided no further proof and people have tried getting one but failed.
