Lieutenant Tsuruku Richards was a member of the United States Colonial Marine Corps. An expert adviser on Xenomorph eradication operations, he was assigned to the Colonial Marine Berserker unit dispatched to TodLab LXI in response to the outbreak there.
The mission to TodLab LXI was a failure, with most of the team being killed and a Xenomorph Queen escaping the destruction of the station. Richards was killed Dr. Piers Cotlow when he confronted the doctor regarding the illegal Xenomorph experimentation that had been taking place on the station, unaware that Cotlow was in fact the man responsible.
