Michael Greene was the chief engineer of the USS Prospect between 2365 and 2370, the USS Shabonee for part of 2370, and USS Prospect (NCC-60056-A) from 2371 onwards, as well as a member of Special Operations. His friends and family called him Mike.
In late 2366 and early 2367, Greene was the chief engineer aboard the Prospect when on the eventual rescue mission in the aftermath of the Battle of Wolf 359. After the battle with the alien ship which caused significant damage to a nacelle, he contacted the bridge after the away team's hasty return to the Prospect to inform his brother and commanding officer Captain John Greene the ship was miraculously repaired.
Greene accompanied the undercover away team to Enika on Goffan III to determine whether the Jenchum Suzerainty was developing a subspace weapon. He also disseminated a great amount of information at a meeting of senior officers early on in the mission. (Star Trek: The Prospect Chronicles: "Starry, Starry Night")
Later in the same year, he was the person who brought Hahn Jun-Seok his birthday cake. On that same day, he and Kari Eriksson worked to find a way to reduce an anomaly's effects on transporting their away team back from the USS Artemis. The duo found by using a coherent graviton pulse, the tetryon emissions from the anomaly would be reduced, and the away team could be safely beamed back to the ship. (Star Trek: The Prospect Chronicles: "Lady Lazarus")
In 2370, he served as chief engineer aboard the USS Shabonee. During this time, he, along with first officer Penelope Koh and counselor Daniel Radke, successfully drove the Boogeyman entity away from the Shabonee. (Star Trek: Shabonee: "The Boogeyman")
