Wood Release: Wood Dragon Technique

The user creates a gigantic wooden dragon, which they can they use for a multitude of purposes including restraining a target, or for offensive purposes. The dragon that the user creates can vary in terms of appearance. While both instances created a serpentine dragon, Chinese dragon, though the first had a short trunk-like nose, while the other two later created did not. It also has the ability to absorb chakra from its target, slowly rendering them unable to use techniques. In the anime, Hashirama was able to cause the dragon to detonate on his target, resulting in a large explosion.

Influence
The dragon created by this technique resembles a creature predominantly seen in Hindu mythology known as the Makara. Over time, the myth surrounding this creature has spread throughout most of Asia, and in Chinese renditions of the creature it most resembles this one: a dragon with an elephant's trunk.

Trivia

 * In the anime, Hashirama's generic dragon is depicted the same as the trunk-like nosed dragon.
 * Hashirama noted that the chakra absorption feature of this technique negates the Chakra Absorption Techniques of a bound target.
 * When the Wood Release: Wood Human Technique was used, this dragon encircles the creature's torso.
 * In certain parts of Japanese mythology dragons are considered deities with power over wood, forests, and water, likely a reference to Hashirama's Wood Release.
 * Obito used a technique similar to this but, instead of creating the dragons with the Wood Release, he used the roots of Shinju to form them.
