Nightwind

The Wraith Queen of Michael Kenmore's hive approached the Atlantis expedition with an offer of alliance. If the expedition gave them the Iratus bug retrovirus they had tested on Michael, they would use it to feed on other Wraith. Elizabeth Weir accepted the offer, and she, Michael, and one scientist were allowed to come down to Atlantis. She agreed to whatever terms the expedition wanted, saying all they wanted was the retrovirus. After testing it on a Wraith Warrior, she feed on the humanized Wraith. The Queen then decided to test it on a rival hive, though the test failed when the saboteurs were killed. Rodney McKay promised to come up with a better delivery system, in return for the schematics of a hive ship. She agreed, sending them a copy. However, the copy was rigged with a computer virus, which downloaded Lantean hyperdrive schematics and the Stargate address of Earth.

After Michael confronted his Queen about their deception, which he was unaware of, she angrily told him that as far as she was concerned, the "stench" of Humanity would never fade from him. When the Daedalus beamed the retrovirus over to her hive ship, the Queen was believed to have been made a human. However, the Females were resistant to the retrovirus, though she was greatly weakened by it. Attempting to feed on Major Lorne, she was killed by John Sheppard and Ronon Dex.
