Alchemist is best for the concept, although a Sorcerer with the Abyssal bloodline and some good roleplaying could work, too.
Beast Totem (Su): While raging, the barbarian gains a +1 natural armor bonus. This bonus increases by +1 for every four levels the barbarian has attained. A barbarian must have the lesser beast totem rage power to select this rage power. A barbarian must be at least 6th level to select this rage power.
Beast Totem, Greater (Su): While raging, the barbarian gains the pounce special ability, allowing her to make a full attack at the end of a charge. In addition, the damage from her claws increases to 1d8 (1d6 if Small) and the claws deal x 3 damage on a critical hit. A barbarian must have the beast totem rage power to select this rage power. A barbarian must be at least 10th level to select this rage power.
Beast Totem, Lesser (Su): While raging, the barbarian gains two claw attacks. These attacks are considered primary attacks and are made at the barbarian’s full base attack bonus. The claws deal 1d6 points of slashing damage (1d4 if Small) plus the barbarian’s Strength modifier.
