BloodBending

Bloodbending is a poorly named (Because it acturally bends blood and the water in the human/animal's body) and forbidden form of waterbending develped by Hama while in the Fire Nation Prison. After her escape she went mad with power and started to kidnap people under the fullmoon.

History of the Technique
About fourty or fifty (Presumed) years before the start of the series The Fire Nation lead by the southern raiders started to raid the people of the Southern Water Tribe. Hama, the last and most powerful waterbender of the tirbe, was finally captured after years of fighting and exaustion she was captured and inprisoned. Each month she felt the light of the Full Moon which inhanced her powers to an extreme amount allowing her to bend the water within the rats which she controlled like a "Dark Puppitmaster." She spent years prefecting the technique allowing her to escape.

After Escape
After her escape she knew she couldn't go back to her native tribe so she stayed in the Fire Nation to exact her revenge. Each Full Moon she used Bloodbending to kidnap a village or a few Villagers to lock them up as revenge. This scared the villagers to an extent where they were scared to go out on the night of the Full moon, some took it to an extreme, like Old Man Ding, who would board his doors his windows with wood, even though the "Spirit" only took people in the Forest.

A Visit from Team Avatar
Team Avatar while possing as Fire Nation Colonists, were encounted by Hama who originally tried to kidnap them until she herd they weren't Fire Nation, she changed her mind and invited them to her Inn. She than taught Katara some of their Tribe's Water bending powers. She was unnaware that the Avatar was one of the boys Katara was traveling with and even tried to kill him.

Strength:
Bloodbending is a powerful technique that can control poeple's boddies' blood and any other form of water in them. While Hama only used the technique only ot kidnap people, the technique can also instantly kill the victem by freezing them inside out or boiling the water for a more painful death.

Weakness
While the technique is powerful, it can only be done under a fullmoon, and another waterbender can breakfree of the technique if they know how it works, also the technique has a time limit sense it can only ben done for a single night. Old man Ding broke free from it when the sun came up, releasing the Fullmoon's power from Hama. The technique can also drive the user mad with power as revealed in avatar extras. Hama used it so much that it drove her to insanity and she took her revenge on the fire nation and hoping that Katara would be driven mad by Bloodbending.

Known Users
Sense the technique was created in secret and as a way to escape, only two known indaviduals know the technique. However it is possible that Hama recorded the technique so it could be passed down to a new generation when she died.

Hama the inventer of the technique and teacher of Katara.

Katara the apprentice of the technique's creator until she turned against her.
