One person on furtopia started a discussion about why there wan not many Avatar fursuits, my answer as follows:

I had seen pictures of Na’Vi costumes in other conventions like Comic Con. I would not expect many Avatar fursonas in the fandom for the reason there no Waking green fur Huskies in Hollywood or anime. 99% of furries look inward to themselves and other furs for their inspiration compare to Anime and Science fiction fans look to outside of themselves for inspiration for example Avatar, Star wars, Firefly, Naruto, etc.. As Uncle Kage puts it, we are fans of our own creation. . Take Kumoricon a local Oregon Anime convention; there were two costumers to every attendee but 99% are cosplaying an established anime character. (ps. you think model nazis are bad, meet a cosplayers they will tear into anybody’s who charter portrayal is not perfect.). Hetalia Axis Powers was the in thing and seen multiple cosplayers portraying the same charters.

Now take any fury convention. We may have 10 to hundreds fursuiting but 99% unique individual variations of characters. It will be very hard to find two of the same fursuit or artwork. This is not to say one will not run into a Stitch, Bolt, or a Br’er Fox at a fur con, but they are just one in a sea of many different creations. This variations and uniqueness in fursuiting, literature, and art is what drew me to the furry fandom
