Torres 216
Torres 216 was a holoprogram created by B'Elanna Torres after she learned that her former Maquis "family" was massacred by the Cardassians in mid-2374. 

Torres would run the program, in which she battled Cardassian soldiers in a cave, with the safety protocols turned off, and as a result would suffer from severe injuries. ()
