The very first My Little Pony special was darker than I expected

[Snoopy Fan 28]

While I was searching up stuff for Friendship is Magic, I came across something about Tirac, the g1 version of Tirek, and I noticed that the original MLP special, Rescue at Midnight Castle, was surprisingly dark. Tirac was a very intimidating villain, and his source of power, the rainbow of darkness, is a very dangerous weapon.
