Mercury

The Red Lotus used a metallic poison on Avatar Korra in 171 AG, in their attempt to end the Avatar Cycle.

History
After the Red Lotus captured Korra in 171 AG, they took her to a network of caves near the Northern Air Temple, chaining her above a pit before administering the poison. Zaheer explained they intended to use to poison to force Korra into the Avatar State, then kill her so the Avatar would cease to exist from the world. A Red Lotus guard metalbended the poison into her, causing her to see hallucinations of her past opponents. After resisting, she was forced into the Avatar State but managed to hold off the Red Lotus' attempts to kill her and freed herself from her chains. She proceeded to chase Zaheer and fight him in the skies above the cave network. During her fight however, the poison continued to take its toll and she began to lose control of her body. Zaheer proclaimed that she could not fight himself and the poison and the same type, and proceeded to take the advantage in the fight. He attempted to kill her by suffocating her, but was interrupted from doing so by the efforts of the escaped airbenders, who created a giant tornado. The massive windstorm sucked Korra and Zaheer towards the ground, and Korra managed to fight the poison again to prevent Zaheer from escaping and pull him to the ground, defeating him.

Korra then fell unconscious from the poison's effects, near death. Zaheer began to laugh as he believed himself to have destroyed the Avatar, but Jinora explained to Suyin that the poison was metallic. Su then metalbended the poison out of Korra's body, saving her life. She then threw it on the ground as Zaheer began to panic, realizing his plan failed.

Effects
The metallic poison is administered to the body by metalbending it into the victim's pores. Once adminstered, it starts to produce a hallucinogenic effect. The body also convulses, with the victim eventually having trouble moving on their own. After a short time, death will result.

When used on an Avatar, their body will enter the Avatar State involuntarily in an attempt to fight it.
