I think the title says it all, but i'll explain anyways.
What i mean with "one- shot characters", i'm talking about those characters that, so far, has only appeared in one episode. Just one.
Just some quick rules;
Cameo appearences doesn't count.
Inanimate objects are also disqualified.
I'll also disqualify any major villains, since Discord has appeared twice now, and a certain character would obviously recieve the most votes if i didn't.
I'd also like to hear what you like about your favorite one- shot character.
My personal favorite is Iron Will. Also, feel free to tell me whom i have missed.
