Wouldn’t she be replacing ADAM, instead of just one of the angels?

According to this post (which is the second posting of this image on desustorage/4chan), the original drawing is by Mistermech. I can’t find it on his deviantArt page, though. No idea who colored it, either.

That is what it looks like…  
To be a goddess.

Arceus?

Someone a fan of Nobody Dies?

I Am.  
By license of She who is known as “I Am”, I have come.  
Though I fly above this base earth in my endless quest, I have come.  
I am the light that fuels the sun. My voice is the song of spheres, and with my warmth I have graced this world.  
Yet despite my benevolence, you have cast down my Avatar. My patience, as have your works of civilization, is come to an end.  
Cities will burn in my passing. Nations will crumble under the wake of my wrath. I am the God-Empress of Ponykind. The Unconquered Sun. I am Celestia.  
I have come.

So… Tempted to tag this as “Evangelion”… ….It all keeps tumbling down, tumbling down, tumbling doooo-awn…”

There has got to be a higher resolution or a wallpaper size of this image.

_Looks @ Picture…. Plays this plays in my Head!

Number 19, Celestia, concept of “The Sun”
