Me: “What can I do with this one, Aphrodite?” (Stabs Twilight three times) “She won’t - stay - still! I wan’t to make them beautiful but they always turn out wrong!” (stabs Twilight a fourth time) “That one, too fat!” (reveals Spike; lying on a table with his stomach carved open with various surgical tools) “This one, too tall!” (reveals Flash Sentry; his head severed from his neck with a circular saw embedded in the wall) “This one, too symmetrical!” (reveals Starlight Glimmer; her upper body split in half with a chainsaw) “And now…! What’s this, goddess? An intruder? He’s ugly! Ugly! UGLY!” (pulls out an MA5B and opens fire) “UUUGLYYYYYYY!!!”

“What can I do with this one, Aphrodite? She - won’t - stay - still! I want to make them beautiful, but they always turn out wrong! That one, too fat! This one, too tall! This one, too symmetrical! And now… What’s this, Goddess? An intruder?! He’s ugly! Ugly! Ugly! UGLYYYYYYYY!”

Plus, you get to shoot fire from your hooves and throw green glowing slimeballs that forces your enemies to help you.
