Worst-case scenario would probably be that I'd be told to remove spoofed images from my avvy... >_< In any case, I was planning on switching to one of my own Monday or so (depending on when I have a chance to upload it).
Also, I personally have no interest in animated avatars because they're usually hard to look at and make out what they're supposed to be of.
No, I usually just spoof my avvies. I don't claim ownership of the original pics, though (otherwise I would be in trouble for it)... I might be able to find an Absol pony, but I don't know about Charizard one.
