Sombra's not a nice guy, even at the best of times. When he has to grow back from a chunk of horn and find all his worm-slaves frolicking around his empire without a chain in sight and some stupid pink mutant with her dumb husband and cotton-candy brat sitting in HIS palace, well, he's just a might bit miffed, you know? This is why you always clean up thoroughly after a battle with the Forces of Darkness, Cadance. It'll come back to bite you otherwise.
Thanks to the always wonderful mustlovefrogs and fanthrose for their help getting this to look right. Also, I blame you badguy101 for Cadance's predicament. I begged you to stop me, but you didn't. So really this is more your fault then mine.
Also hey look, someone actually has their cutie mark for once.
