The IM Gay trilogy by kwarkman85. Not only do you have IM Meen take several levels in badass by defeating Hectan and then snidely rejecting Ganon's offer to join him and then trapping him in the book of Koridai, you have Link changing from a naive ditz to a certified Badass after Meen also traps Zelda and The King in the book of Koridai. And then there's the showdown between the two in the conclusion of the trilogy.

Robotnik then crosses the Moral Event Horizon, when he decides to violate her and the screen Fade to Black, only to give time for Reimu to summon "PODER DE LA VARA!", which curbstomps him! After the dust settled, it was revealed that Sonic and Aya recorded and transmitted everything to the entire world, destroying his reputation! Then Marisa shows to defend her friend and shots a laser beam-spell, finishing him off!
