Ensign Zier was a female Bolian Starfleet officer who lived in the 23rd century. In 2259, she served in the sciences division aboard the USS Enterprise.
That year, she tried to sign the scorch with Ensign Christina as part of Enterprise bingo, but they were caught by Una Chin-Riley and La'an Noonien-Singh. They were then punished by having to micro-clean the transporter pads under the supervision of Chief Kyle, whom Christina and Zier considered to be mean. La'an later confiscated the Enterprise bingo list from Zier's quarters whilst she was conducting a routine inspection. (SNW: "Spock Amok")
Zier was portrayed by Torri Webster.
