Breaker is a super-hero like character with some odd devices equipped. Coldness is the theme of the character, both in personality and her abilities. She also has super strength has essentially never been defeated by anyone. Her lines reflect her sense of superiority and hostility, but she isn't evil per say since her job is to keep the peace. A medium pitch voice with a sense of intimidation and intensity is needed. There is no rule on the accent for this character but American English is the standard for the project. There is a clip linked as an example with a laugh and an exertion sound in the project description to give you an idea of what I'm looking for.

Audition lines:
My fist could split the earth. Best be out of it's path.
...a chemical so cold it can freeze time.
You can't even move!
Nothing matters but the final blow! (Shouted)
Ha! Ra! Hoo! (Fighting sounds)
Ahhh (Death/hurt)
