Unnamed Curse Mark

This Curse mark was created by Kabuto Yakushi using the combined cells of Jûgo and Juubi's. This curse mark automatically activates when the user is in danger, providing him almost unlimited Chakra, the ability to distort time and space for a short time (thus leaving the user in terrible phisical pain) and the power to cast a special Genjutsu named Kara no Jutsu. It was stated by Kabuto that this was the most powerful of the curse marks.
