I've had a number of Avatars and names, my favourite one being the chicken wielding a knife, but as my roster of Hamsters grew (and idiots from the forums started making toxic contact in-game, one must literally have paid for a sub just to attack me over WOTLK vs MoP-opinions) I settled for my current alias and avatar. The avatar is an early image of my first hamster in 10+ years that I got in 2014, named Olivia.
I'll switch to a more recent avatar picturing one of my current (5) hamsters soon.
