Major Adrianna Tereshkova was one of Russia's pre-eminent cosmonauts in the Mir Space Station program. But all of that ended on July 28, 1980, when her ship was destroyed by unknown space debris and plummeted to Earth to crash into the Antarctic. Major Terehkova and her two crewmen were presumed dead. In fact, the spacecraft had been struck by a shard of the Void entity that has journeyed the time continuum in order to escape death at the hands of the Gnome. This portion of the Void entity, that took possession Adrianna Tereshkova, used her as a vessel through which to gather Jacob Marlowe, the Lord Emp, and his Gifted Ones into the team now known as the WILDC.A.T.S. She needed them in order to face down the Gnome once again and deny him the power that would have assured him global domination.

Powers

Because she has merged with the Void entity, she can sense and manipulate spacetime, giving her visions of the future and allowing her to teleport. With difficulty she can teleport others, but when she was with WildCATS Emp often gave her a power boost using his energy powers to make it easier.
