FULLVEIW
These are all of the changes my fursona went through from the time that she was created roughly 8-10 years ago.
FROM THE BOTTOM UP
1: MoonShine ; wolf
What makes her special: The only phase of my fursona that has NO KNOWN physical or digital art of her in existence. I can still remember how she looks because she was also the first CHARACTER I ever created. She is also the only wolf.

2: Toboe Sora; cat/bird/dog hybrid
What makes her special: Only winged fursona and only fursona with a short tail.

3: Keirii Night: ringtail lemur
What makes her special: Only lemur. First to have a completely anthro form.

4: Madam Rat; african gambian rat
What makes her special: Only rat. Only fursona with a PERMANENT accessory (Crown). First to feature 'Madam' as a part of her name

5: Belle of the Snow: flox *flower fox*
What makes her special: First fursona that was considered a part of the furry fandom. Introduced me to the fact that I was furry and denying it. First to feature my current markings, Only Flox

6: Glacia # Cross fox
What makes her special: First to have three tails and flopped ear. First of the current colour scheme.

7: Glacia # Fennec fox
What makes her special: First fennec.

8: Glacia NOW: Fennec fox
What makes her special: First of the 'Glacia' series to have one tail. First to have suit made of her. And The one I love the best. :3

I will likely not change Glacia further as I am very proud of her current appearance. She is the only one that I have ever actually connected with and felt that she IS me, and I AM her.

BUT! That does not give you permission to claim any of my others as yours. I MAY offer them out later, BUT NOT NOW.
if you want to use the idea of a fursona 'totem pole' like this, give me credit and show me how yours came out! I will offer these as HANDDRAWN badges if anyone is interested, they will be either ten dollars or as a trade for a full body badge.
