Sure. It seems like Robilar was a Barbarian after all:
Come and Get Me (Ex): While raging, as a free action the
barbarian may leave herself open to attack while preparing
devastating counterattacks. Enemies gain a +4 bonus on
attack and damage rolls against the barbarian until the
beginning of her next turn, but every attack against the
barbarian provokes an attack of opportunity from her, which
is resolved prior to resolving each enemy attack. A barbarian
must be at least 12th level to select this rage power.
