So... i think monty was pointing out the fact that her enchanced bullets create dark bird shapes. and along with the fact that her 'hoodie' at the beginning looks like another cartoon character, i'm going out on a limb and i'm gonna say her last name is Raven.

Let the war begin.

But seriously, other than a lot of rendering mistakes and some twisted hands and fingers, these were the only significant things I found. Black was not amongst the beasts, if you were wondering.
