Well, well, well.

Who do we have here?

It's the ONE and ONLY King Sombra!

First appearance: Season 3

King Sombra - the former ruler of the Crystal Empire. Was defeated by the princesses the first time. During Season 3 he was a failure to lots of people. Came back in Season 9, where showed him in a better way being a villain. Also has lots of appearances in the comics series.

What I love about him: his own backstory (comics series, My Little Pony: FIENDship is Magic Issue #1, becoming good in the comics series (Friendship is Magic Issue #37), has his own Alternative Universe version (comics series, Friendship is Magic Issue #18), he's one of the best villains in My Little Pony series, as I think (but it could be better to see him in Equestria Girls, same with the other villains), seeing a fan-made version of him fighting the princesses (Fall of the Crystal Empire)

What I hate: he was defeated very quick in Season 3, not being able his backstory (Hasbro, I'm talking about you!)

Though he was easy to be defeated in Season 3, he fixed himself in Season 9 and became a better villain, the one, I'm sure, lots of people wanted to see.

He deserved to be here.
