History
When the Red Lotus finalyy Korra they while chained her with platinum cuffs, resisted Zaheer as the Metal Clan engaged P'Li. Tonraq assisted his daughter too but was thrown away from the battle. Lin then acted as a distraction for P'Li as Suyin metalbended her vest around her head before she could fire, the resulting confined explosion killing her. However, Zaheer is able to escape with Korra as he demonstrates the unique airbending ability to fly.[9]

The Red Lotus took the Avatar to their mountainside hideout, where they planned to use poison to force Korra into the Avatar State, where upon they'd kill her, ending the reincarnation cycle. Other members of the Red Lotus MetalBent the Poison into her skin. But when Korra entered the Avatar State, she is able to break free and engages Zaheer in an aerial battle. Meanwhile, Team Avatar had discovered the hideout and Mako and Bolin respectively engaged Ming-Hua and Ghazan. Mako disables Ming-Hua with lightning before going back to help his brother and surround Ghazan. The lavabender refused to return to prison and lavabended the cave down on them to take them down with him, though the brothers were able to escape.

Else ehar in the Prison the captured airenders manage to grabe the keys from on of the sentries and Syuin blasts a rock at the guard allowing them all to escape.

Meanwhile, the aerial battle goes in Zaheer's favour as the poison takes a toll on Korra, giving Zaheer the chance to bend the air out of her lungs. Before he managed to finish doing so, the freed airbenders create a tornado under Jinora's direction, catching Zaheer and enabling Korra to bring him down through metalbending. The Beifong sisters then restrained Zaheer with earthbending. However, as it seemed like Korra had succumbed to the poison, Jinora reveals that it's made of metal, which Suyin bends out of Korra's mouth, saving her and thus foiling Zaheer's plans, though he had still succeeded in creating chaos in the Earth Kingdom.

Even though the Zaheer and his companions are either incarcerated or dead, other members of the society may remain at large.
