My Little Pony: Friendship is Magic - Rated 'L' for Leverage

He was a fine villain that doesn't need to go on a murder spree.
Also, he use Discord to his advantage by exploiting that Discord never went through a full face turn.
Also, in this situation, they go with words like destroy or eradicate.
Also, it's not about a mature rating, but on how far a network with let them do.
Avatar series and Adventure Time have the evilious beings and they are hard Y7 to PG.

"That wasn't very Everyone…"

Now that I think about it, maybe Tirek would have been a bit better of a villain if he was in a show with a more mature rating to it. Him made into more of a psychotic beast man, ripping off limbs and making you eat them with a grin on his face, could fit. You know, instead of just growling angrily at everything while Discord does all the work…

As it stands though, he's still just generic dreck..
