Uchiha Summoning: Dragonsbane

A technique usable by three or more members of the Uchiha Clan at one, the users will each sync up their chakra and use the Summoning Technique, calling forth a massive black dragon, which they can then use to assist them in battle. Using his Ten-Tails Chakra Mode, Raian can actually summon the creature all by himself, due to Datara's tremendous chakra.
