WARNING: THIS POST (and probably the entire thread) WILL CONTAIN NUMEROUS SPOILERS... READ AT YOUR OWN RISK!
First off, for those poor souls who have never seen TVTropes, it's here.
And for those of us who have, surely you've seen at least a little bit of your story in the place? If you're like me and recognize some tropes as things you've done, but have never bothered to get them out anywhere... well, now you can!
Fic: Metal Coat
Crowning Moment of Awesome:
This may just be the author's perspective, but Chapter 2 of Metal Coat was pretty dang awesome.
(Oh yeah, as well as half of chapter 16 and all of chapter 17 for our dear friend Mesprit...)
Heel Face Turn:
Cyrus - gradually. (It's made pretty obvious in Chapter Eleven - you know, with the whole Magnezone thing.)
This one, I think, should be pretty obvious.
Now who would have thought our dear little pink fluffy thing was capable of having a bad thought in her mind?
What? Cyrus leaps into the Distorted World in Platinum? DANGIT!
My God, What Have I Done?:
Yami, the end of chapter 17: "Arceus... what have I done...?"
There is probably some more I forgot... if you find any, point 'em out. xD Anyway, go browse around TVTropes for a while, and come back with a varying amount of tropefindery.
