Just a heads up, theres a pretty neat Evil Conversion in Finister Foul's Pink Pussycat story, The Wicked Fun Pack (The same comic that had that Bimbo TF) where the Heroine Snowflake has an evil Black Hat put on her then a sequence follows of her turning into Frostbite, a evil villianess version of herself.
It is a paysite mind, but if you want an idea of what the two look like, both were in this comic (Except there's also a BE during the TF)

And this is where you can find the comic and Finister's other comics.
