Super Beast Imitating Drawing: Dragon

Using his scroll, Sai uses Super Beast Imitating Drawing to create an ink dragon, which he can ride on as it attacks the opponent.

Trivia

 * While unnamed in the anime, this technique was named in Naruto Shippūden: Ultimate Ninja 5. When used as part of his ultimate jutsu, Sai creates this technique from a giant summoned scroll, which the dragon then carries his opponent into the air and slams them onto the scroll, as it returns into the scroll.
 * This technique appears to work fine in water, despite Sai saying Super Beast Imitating Drawing techniques don't work as well in rain.
