Xero is one of the 4 leads. He is a robot with a dark past that was engineered to murder. He is loud, sarcastic, reckless, and aggressive, always ready to fight.

If you want to audition for the role, you can use any pre-existing lines you believe would fit the character, or you could make your own if you wish.

You will have to be prepared to be called again, as this is a role for an animated series posted on YouTube.
