Ensign Lyle was a member of the Coast Guard in the early 2190s. Lyle was stationed on The Dutton, which was under the command of Commander Barton.


In early 2192, Lyle was part of a clean up effort above Earth's atmosphere to prevent large pieces of space debris from falling to the surface. The Duttonwas in the middle of a salvage operation on an old derelict that wandered into Earth's orbit. After he sent in the probe to investigate the ship before Lyle and his commander destroyed it, the probe managed to get snagged. When the probe was pulled back, the two crew members saw a strange creature holding on to the probe as The Dutton pulled the probe in . The two panicked and worked franticslly to space the creature from the ship, but when the two looked back in the cockpit the creature was standing there. The creature made its way to Lyle, grabbing him and proceeded to kill him with a tongue-like appendage with teeth by running it through his head. The Dutton was caught in the timed explosion set by Lyle and Barton and only the "Blue Box" recording of the events remained.
