It's one thing for Aneesah to get angry and go absolutely nuts, controlled and calculated yet brutal and extreme attacks. But if you get something in her to snap, something to really break something in her, you'll find her berserk form. A form which an END walker (still working on the ender species name) takes that is similar to an Ender man, but much more hostile. It will take the aproadh of someone close to her or just some time to calm down to turn her back to normal.
