This is the first I've seen or heard of them but I adore them. I'd pay for the Emma one for sure. 

I'd know he's nowhere near the top of the list, but I'd like to see Havok. I think out of all the X-Men, he's has the most drastically different costumes...

As a gambling man, I say Wolverine will be featured in one. I'm betting on a dark horse, I know.

Shocking, isn't it? He's such an underused character.
 
 
Seriously, though, I'd love to see one for Beast. "

All I can say is, while Emma and Sabertooth had very beautiful pieces of art for variant covers (that are sure to belong as wall poster rather than variant over-priced covers) Rouge and Kitty are not getting the star-treatment love. 
 
I won't be buying these, but I wonder if this has anything to do with X-Men: Prologue? 

I'd like to see Cannonball since his costume changes so much

And I completely agree. He's an awesome character who has literally evolved. "

Indeed, his style has been altered radically through the years.
 
PS - Nice avatar. "

Why isn't Kitty in her space suit in hers? Does that mean she's not going to be in it, anymore?

Wow!! I'm looking forward to Cyclops's and specially Warren, hope both of them have one. 

Who is the artist on these, I adore them!!!  
 
It's not that much extra cash, I'd shell out. 

eww i'm going to have to get a few of these

I love the kitty one and I am going to spend the extra cash for it. 

Delightful, but I still prefer Deadpool Variant Covers LoL.

 oh i love emma's evolution cover !! but why doesen't  include her gen x costume? i konw the yellow knee high boots was dumb, but since it is called "evolution  cover", they shouldn't  ignore her history in gen x.....i have to saythe art is awesome though.

I like Emma's one here the best, just for the composition (and well art) I wish Rogue's had a bit more zing. Professor X will go from him sitting to standing, to sitting then standing... (unless that decide to let him get a bit freaky with his Morlock uniform ;) 
 
Awh man i miss me some old Rogue uniforms. Beasts one should be fun. Psylocke's is going to be confusing... wouldn't mind a Dani Moonstar one myself, she had some cool looks.

Not bad.

I would like Gambit; Jubilee covers by James Jean orJoao Ruas. Meh I would settle for a Nightcrawler or even Dazzler.

" Professor X will go from him sitting to standing, to sitting then standing... "

 Professor X will go from him sitting to standing, to sitting then standing...

I know she probably wouldn't get drawn, but I would LOVE a Moonstar one. She is one of my favorites, and her fashion has changed quite a bit over the ages... godkiller bad@$$ery would be worth it alone.

Kitty was so cute XD

It's probably less likely since he's dead, but I want a Nightcrawler one!

Please, please PLEASE let there be a Psylocke one!!!

Really?  Where's that?  He's standing on the cover...
 

" @doddy: Cool art, thanks!  Hopefully it's a flashback.  I hate it when writers can't come up with decent characterisation so they put him back in the wheelchair... or back on his feet again. "

I kinda like them. Might try to get the Emma one, at least. Wish they were actually on relevant comics, though. It's a weird trend of slapping on variant covers that have nothing to do with the actual title (e.g. the Super Hero Squad variants).

Dazzler and Boom Boom.  They both have had many changes.  And from your recent profile I learned that you are also a Boom Boom lover

The variants that id like to see, other than the Emma one, are; 
 
Psylocke 
Storm 
Nightcrawler 
Beast 

Im a big fan of those covers just because I ike seeing a character's progression and it's fun to see some of their old costumes 
But emma doesn't really have much variation in her look so her's bores me XD

Although I love art like this Rogue's are just awful her Eyebrows are non existent and it has no dynamic like Emma heck Kitty's wasn't too bad.

 that are truly beautiful and I would like to see other Marvel characters

Dazzler needs one!
