Tiger Soul

This form of enhancement does not simply improve senses and reflexes, but physically changes the body. Strength, speed, and agility are all increased to super-human level for a brief time, but with a number of side effects. The user grows real fangs and claws, feline eyes, ears, a tail, and striped fur. They essentially become something of a tiger/human hybrid for the duration of the technique. However, while powerful, this technique can very quickly burn through chakra, and should therefore not be used for prolonged durations.
