My Little Pony: Friendship Is Magic2010

Rainbow Dash:
[about to fight a large group of changelings] Looks like we're gonna have to do this the hard way. [she runs up to one changeling that has already copied her appearance. The two mirror each other for a few moments before the changeling shoves Rainbow back to her friends] How did you...?

Twilight Sparkle:
[the remaining changelings all disguise themselves as one of the mane six] They're changelings, remember?

Changelings:
[five changelings, all disguised as Twilight, stick their heads in and imitate her, grinning smugly] They're changelings, remember?

Twilight Sparkle:
[she and her friends are now surrounded] Don't let them distract you. We have to get to the Elements of Harmony. They're our only hope.

Applejack:
[face to face with an undisguised changeling] OK, this is just gettin' weird. [Twilight shoots down a pile of Applejacks and telekinetically pulls one of them out] Real me! Real me! [Twilight relents and places Applejack upright on the ground]

Pinkie Pie:
[meanwhile, Pinkie Pie watches another changeling quickly go through the disguises of Rarity, Rainbow Dash, and Fluttershy] Eeheeheehee! Do me! Do me! [the Fluttershy changeling rolls its eyes, and transforms into Pinkie Pie, complete with a big happy grin and arms wide out] Meh, I've seen better. [she grabs Twilight and proceeds to use her horn as a magic machine gun, shooting down groups of changelings with bursts of Twilight's magic]
