Seal of Confrontation Edit
The Seal of Confrontation (対立の印, Tairitsu no In), which looks like a half-tiger/ram, is the symbol of combat and is a universal sign of engagement between shinobi. It represents half of a seal that might be used to activate a ninjutsu. This motion is often used to concentrate chakra, and many shinobi are seen initiating simple, basic techniques as well as few complex ones after making this seal. Deidara also often used this when he detonated his explosive clay and Sai used it for his Super Beast Imitating Drawing. Madara Uchiha's and Hashirama Senju's statues at the Valley of the End are both forming the Seal of Confrontation whilst facing each other.
