Tia Karim

Colonel Tia Karim was a member of UNIT who worked with the Claw Shansheeth of the 15th Funeral Fleet, a rogue group of Shansheeth, in order to travel the stars in the Doctor's TARDIS, as there was "nothing left for me on Earth, not anymore". To reach her goal, she acted as a representative chosen to inform Sarah Jane Smith of the death of the Doctor. Once she accepted to come to the funeral, along with Rani Chandra and Clyde Langer, Tia showed them around the UNIT base. She succeeded in locking Rani, Clyde and Santiago in part of the base, and attempted to literally roast them by trapping them in the air conditioning and turning the heat up to maximum. She was aware the Doctor would save them allowing the Shansheeth to capture Sarah Jane and Jo. They were attached to a Memory Weave but it overloaded due to their many experiences. It self-destructed and Tia was caught in the blast and killed. (SJA: Death of the Doctor)
