Talk:The Crystalling - Part 1/@comment-3410511-20160329211339/@comment-1031724-20160402013315

When he was banished, we saw him turned to shadow and his disembodied head going into the ice crevice. With the Crystal Heart, he was shattered to pieces with a "rays of light" effect. Meghan McCarthy, the writer of the episode, also said he was dead.

Besides, why is it so hard to believe this show can kill villains either by magically destroying them or having them fall to their doom, when G1 did it twice and Disney movies used to do it all the time? If it was afraid to do that thinking it was too much of a "kid show" for it when obviously G1 and the G-rated Disney movies weren't, it wouldn't help the show's reputation.

And even for those who can make a case that Sombra survived, in the episode The Lost Treasure of Griffonstone, Arimaspi falls into the Abysmal Abyss, and later we can see his skull in there so we know he's dead. And there's also the Pinkie Pie clones which were collapsed into magic by Twilight and sent back into the mirror pool, returning to nonexistence. I want to mention the Windigos and the King Timberwolf but those are a little debatable, and I won't even start on Chrysalis.

To answer your question about the comics: They never really said "killed" with him, but he is essentially depicted as a ghost before Radiant Hope revives him.
