The Bloodbenders
Her skills were known now, and Hama was once again back in prison, she had expected to escape, at first she was in a dry metal cell as usual, but she would not be broken, and she would not be beaten. Before the Full Moon could grant her it's unique powers she was moved to another cell, deep in the Fire Nation capital, in the high secruity Boiling Rock Prison. The war was over, The Fire Nation had been defeated, but Hama found herself ultimately defeated herself. Someone named "The Mechanist" had eingeered her special cell, waterbending proof, but she grinned in the face of irony, for no cell could contain her true power. Her power to enforce her will on others.
Months passed, the guards must have known of her skills, that Katara was clever, if no one was around to bloodbend, she could not force her escape, she just patiently waited for another way out, but none came. Her legacy would die with her, it was true, she had taught Katara how to bloodbend, but she would not continue or teach anyone this art, she had to have a fresh start, with one who was willing to enforce his will on others, one who had no qualms about control, one who would be more than willing to continue the art and power of bloodbending to the rest of the world, and after twenty-five long years, Hama found her student. A waterbender jailed for crimes against Republic City and leader of the Red Monsoons, Yakone.
The guards were fool enough to jail them together, every full moon when the guards were gone she would teach Yakone the art of bloodbending, and unlike Katara he reveled it's power, ready to enforce his will. Hama had suceeded in creating the next bloodbending master. Then she enstated the next part of her plan, she engaged in a fight with Yakone, and Yakone was moved to another cell, he promised that he would escape himself, and then free her.
It was one full year after Yakone was imprisoned, he attacked the guards and escaped the cell, she could feel it in her blood that Yakone had suceeded, and withing minutes she was realized from her cell, together they attacked the guards and escaped the prison cell. At a campsite a few days later she congratulated Yakone.
"Thank you for helping me, Yakone" Hama told him. "You have progressed far more than I ever dreamed, now will get revenge on Katara for the years I spent in prison. For the years I was...GAHHH". She couldn't believe her eyes, without the help of a full moon, the man was tossing Hama around like a ragdoll.
"How?" Hama asked. "HOW DARE YOU!". She tried to fight back, but her bloodbending was not strong enough, she fought for as long as she could, but Yakone's grip was too strong, and then he closed his hands like a fist. Hama fell quicker than she was put under his control, and her dead body hit the ground with a thud.
"My power is beyond your comprehension, old hag" Yakone said, laughing. "I am the greatest bloodbender, and only my legacy is worthy of this great skill". Yakone looked out at the landscape of Republic City and grinned. "So. Revenge on the Avatar and his puny wife. It would be my pleasure".
If you watch Out of the Past you pretty much know what happens next, but I just thought linking the two would be nice. Hama is the only logical source from which Yakone could have learned Bloodbending. If you disagree, please comment in the reviews. If not, please comment in the reviews. Thank you.
