Kila Marr

In the fictional Star Trek universe, Dr. Kila Marr is a xenologist dedicated to the study of the Crystalline entity.

After the entity destroyed all life on the Omicron Theta science colony, including her son, in 2338 she became obsessed with destroying it. When the USS Enterprise (NCC-1701-D) encountered the entity in the episode "Silicon Avatar" in the year 2368, she shattered it with high intensity energy waves under the guise that she was communicating with it.
