|After being possessed by a neural parasite|
Captain Tryla Scott was a Human Starfleet officer and commanding officer of the USS Renegade. By the mid-24th century, she was the youngest Starfleet officer to attain the rank of captain, which made her something of a legend.
In 2364, Scott met with fellow captains Jean-Luc Picard, Rixx, and Walker Keel at Dytallix B to discuss the infiltration of Starfleet Command by neural parasites. However, Scott was subsequently infested by a parasite. While under its control, she attacked Picard and William T. Riker inside Starfleet Headquarters. Riker was forced to fire at her with a high-setting phaser blast, upon which the parasite fled her body. (TNG: "Conspiracy")
