Animagus Quiz!
Eagle. Proud and fierce.
What Is Your Animagus?
brought to you by Quizilla
I don't know about being fierce, but I like the eagle better than any of the other options.
P.S. to Chresimos -- I haven't forgotten your question -- in fact I'm in the middle of composing the answer, but the file's on another computer and I can't get to it right now. Some time this weekend, though.
