Fluttershy: My dear Rainbow… you lack… vision. You want to turn people into mermaids out of leg envy and for the loss of your career as an athlete, as a runner. You are so short-sighted about this, my dear blue girlfriend.
Rainbow: Fluttershy… what has gotten into you?
Fluttershy: mmmmm….. determination… bravery…. and perhaps a bit of righteous cruelty. That's what has gotten into me. You see, my blue morsel… Mankind has been destroying nature for so long… and I will make them pay. I will sink their world, ship by ship, turn them into merpeople and make them clean up MY ocean, up to the last piece of plastic and trash.
Rainbow: Whoa, whoa girl, I am all in for ecology and nature, but you sound… totally like a villain. That's not cool at all!!!
Fluttershy: It was your stubbornness that made me use the ATTITUDINATOR to become brave enough stop you. You’re fighting so you can watch everyone around you become a mermaid and now regret it when you find somebody of your same species that not only puts you in your place, but will own you too. Think Rainbow, Think!
* Fluttershy makes a quick movement with her finger and snaps Rainbow's seashell bra bridge*
Fluttershy: Ah… much better. Now, girlfriend, join my army of sea creatures… or I will make Narwie here skewer you…

Part of a series of drawings for :iconannonmyous:, whose SFW versions will be uploaded here some time after being in my Patreon (this one has been up there since October)
This is a standalone, (as you guessed and as you know) part of the Equestria Girls series of My Little Pony, following my fan-story Equestria Mermaids.
:iconannonmyous: wanted to see how the girls would turn out if they became their evil selves from IDW's "Ponies of Dark Water" comic series
