My GaiaOnline Avatar -- Lapfox Trax

My GaiaOnline username is Lapfox Trax
I wanted to have an avatar that I could change from one Lapfox Trax character to another. haha 
I decided to make my original avatar inspired by Fracas from Renard's game called SharkAttack. 
Fracas is one of the characters and she is my favorite. She's so badass and what my favorite thing about her is that she is the only shark that is most likely to eat you. 
Also, the bat says "Property of TQBF (The Quick Brown Fox). The purple stuff on the bat is TQBF's blood (It's pinata blood. CHILL OUT).
