Vadic

Vadic is a Changeling and captain of the warship Shrike in the third season of Star Trek: Picard. She was one of ten Changelings experimented on by Starfleet scientists after the Dominion War in an effort to create super-spies; after escaping, she led a rogue Changeling faction and adopted the face of her tormentor. Allied with the Borg, she pursues Jack Crusher across the galaxy and takes control of the USS Titan-A, but dies when the bridge is opened to space.
