Michael Jonas was a member of the Maquis who had been part of Chakotay's crew when their ship was pulled into the Delta Quadrant. Jonas and the other Maquis crew eventually joined the crew of USS Voyager.
After a series of repeated Kazon attacks, Jonas was one of the former Maquis who questioned Starfleet regulations regarding the transfer of technology, particularly after the death of his friend Kurt Bendera. When Jonas saw his friend Ensign Hogan ask Lieutenant B'Elanna Torres to contact Seska behind Captain Kathryn Janeway's back, he decided to take matters into his own hands when Torres refused to do so. (VOY episode: "Alliances")
Jonas began sending messages to the Kazon, using the power grid. He sent the messages out in the waste energy produced by the starship, making them hard to distinguish from normal background noise. Jonas communicated with the Kazon-Nistrim a number of times, including when Tom Paris broke the transwarp barrier, and when the crew encountered the Cardassian Dreadnought. (VOY episodes: "Threshold" and "Dreadnought").
At about the same time Lt. Tuvok became aware that someone on the ship was sending covert transmissions to the Kazon, but did not know it was Jonas sending the messages. He and Captain Janeway recruited Tom Paris in an operation to expose the person sending the messages. Paris played the role of a man dissatisfied with life on Voyager, and played the role very convincingly. As part of plans, Tom Paris put a request to leave Voyager and join a Talaxian convoy. A short time later, Paris was kidnapped from the convoy. Once on the Nistrim ship, Paris found the evidence they were looking for, and he escaped from the ship.
Paris was able to inform Janeway that Michael Jonas had been sending the messages. Meanwhile, Jonas was in engineering, trying to sabotage the ship when Neelix encountered him. Neelix had been doing his own investigations, and caught Jonas in the act of attempting to disable Voyager. The two men fought, and Jonas was killed when he fell into a plasma fire near the ship's warp core. (VOY episode: "Investigations")
