Bellatrix has long wavy/curly black hair and dark eyes. She is vicious and cold, almost unapproachable from a public standpoint. She is ruthless, and cruel, and sadistic even, especially towards Muggle-Born Wizards and "Dumbledore loyalists." She is absolutely fanatical as an aspiring follower of Lord Voldemort, and can be downright cruel to those who oppose it. She is a fun, enthusiastic, extroverted companion to those she cares about, but cannot stomach betrayal of the "cause."
