An organizer of gladiatorial fights and a member of the Exchange, the Lady of Pain eventually came across the Devaronian Tyresius Lokai, a target in the Great Hunt in 3643 BBY. When Lokai's bounty hunter came to her compound, the Rattataki organized a gladiatorial match between the hunter and Borga, a Gamorrean under Fell Dargun. The hunter emerged victorious, but Lokai managed to escape from the Lady of Pain's custody before he could be handed over to the hunter.
The Lady of Pain was voiced by actress Nika Futterman, who also did the voice of Asajj Ventress for the TV series Star Wars: The Clone Wars.
