Aboard the Alexandria[]

In 2380, she transferred to the USS Alexandria as a Gamma shift navigator. (Star Trek: Odyssey: "Eve of Twilight")

Despite her condition, she assisted her comrades in avoiding capture by Imperial forces. After returning to the ship, she was promoted to Lieutenant. (Star Trek: Odyssey: "Spectre's Rose")

Michelle, along with the majority of the crew, was stationed on the Ba'ku planet in a ground assault against the Terran Empire to keep them from having a foothold in Federation territory. (Star Trek: Odyssey: "Requiem")

She received the Trinn symbiont from Torkien Trinn who was dying of old age. She was no longer Michelle Stull but now Michelle Trinn (Star Trek: Odyssey: "Thirty-one")

Trinn, along with the rest of the survivors of the Alexandria, was stationed at Deep Space 9 until a new ship could be given to them. (Star Trek: Odyssey: "Distant Stars")

Personal life[]

Michelle had a pet Tribble that she keeps in her quarters. This particular Tribble had been fixed so it can't reproduce. After being sent to sickbay after having a control board explode in her face during the battle in the Chin'toka system, Doctor Plumley sent her to her quarters, not allowing her to return to duty. She was able to save her Tribble when the order to abandon ship was given. (Star Trek: Odyssey: "Distant Stars")

Trinn symbiont[]

The Trinn symbiont is about as old as the Dax symbiont. It has had a few past encounters with the Dax symbiont. Adrias Trinn dated Emony Dax when the two of them went to the University of Mississippi. Emony later broke up with Adrias and began dating a doctor by the name of McCoy. During their relationship, Adrias picked up Emony's habit of standing on her head to relax. Due to Adrias picking up this habit, Michelle picked up the trait. (Star Trek: Odyssey: "Distant Stars") Because of Adrias's hurt feelings, the Trinn symbiont did not want to experience these feelings again and does not want any of its hosts to date for the time being. (Star Trek: Odyssey: "Thirty-one")
