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.
