Sunset Shimmer will revert to evil!

In the end credits of the actual movie, Twilight is removed from earth-side billing entirely. Sunset and the other 5 are shown exclusively as the human group.
 
So its less Marvelous TK’s personal consideration, but the consideration set by DHX at the current status quo. So until something changes after the end credits of Rainbow Rocks, pony Twilight is not a member of the Humane 6.
 
I, too, think the ‘humane’ joke is clever, and should be applied to denote the new human Elements of Harmony. It might not be long until we are adding Scientist Twilight to make it the Humane 7th.

@Mr. Horrible  
Also wow I can’t edit even after a split second but also personally I consider Sunset Shimmer the Sixth in the Humane Six after that movie, and Twilight to be the Seventh when that pops up, but apparently that’s a point of contention since the Humane Six tagged vary on this point. That’s something that really does need to be settled, I think.

@Mr. Horrible  
They are a very humane group. They take part in all sorts of humanitarian efforts! You question this?
 
(That is to say, I think it’s clever. Both a combination of ‘human’ and ‘mane’ and, you know, being a word that is real and applicable? I quite like it.)

Might I suggest just “Main 6” to denote the human versions of the Mane 6? “Humane 6” just sounds awkward and forced.

HUGS! Hugs are always good!
