The Barbarian is the first of four confirmed classes in Diablo III. It is a continuation of the Diablo II Barbarian class with a slightly changed look and revamped skill tree. The male Barbarian is reportedly the same Barbarian featured in Diablo II, now depicted as an aging man with a white beard and graying locks, yet with the same musculature as before.
In addition to the male Barbarian, a female version of the character is now available. She is depicted as a muscular woman with striking red-orange hair. The backstory of the female character is yet to be revealed..
Gameplay footage released by Blizzard has extensively featured the male Barbarian.
I came to see firsthand the barbarians, those near-legendary, immense, relentless, dual-wielding furies of combat dwelling upon their sacred Mount Arreat. Instead, I stand here looking at a mountain that has been torn asunder by some extraordinary force. The sight, I must confess, is incomprehensible. Yet what I see before me cannot be denied.
