My favorite Monthly Collectible is the Ascended Demon. Mainly because if you wear the Fitted Belts it looks like Leeloo from The Fifth Element, and that is one of my all time favorite movies with favorite actors/actresses.
i liked coco kitty because i love black cats with yellow/orange eyes :3 I cosplayed as him once in my school in grade 10 at a random giving time i said MEOW and i think i crapped my teachers pants....heh w/e ^,.^
The shadow spirit is my favorite October MC. It was the first thing I ever bought way back in '06 when I first joined. October's collectibles are always special to me for reminding me of when I joined Gaia in October around my birthday. It will always hold a special place in my inventory because I bought it myself. I used to think I looked so cool having it on all the time, no matter what.
