Thomas J Mckenzy

Mckenzy was born in Paris, where his mother's family had spent several generations. His father was an officer in the marines, though this line of work occasionally had the family wondering, as he would often be called on assignments alone. While many couldn't be bothered with theorising, Mckenzy often wondered just where his father went when he wasn't at home or with the marines. That question was answered very quickly, however, when he was permited to accompany his father on assignment to Deep Space 5. The assignment, he would later learn was part of a string of intelligence movemence in the sector, was to have lasted 3 years, though Mckenzy would have more than likely returned to Earth long before then to attend the accademy. Unfortunately, Michael's cover was blown, and to this day how is unclear, though it is suspected someone in starfleet had a hand in it. Michael subsequently didn't survive the mission, and even after the news of it reached Earth, Thom spoke nothing of it.
What he was able to take from his travels with his father, however, he credits more so to the questionable and often barely legal company he kept, both on DS5 and on Earth. When not occupied with his studies, something his mother as a Starfleet officer made sure he was often, he was doing exactly what he shouldn't, and occasionally being brought home by the nearest security officer. His entire focus changed however after his father's death. Hence his joining Starfleet. As far as those around him are made aware, he joined for the same reason they did--to protect their homes, and contribute to the defence of what they believe. He, however, is motivated by one thing: justice. He knew an officer in the fleet was the cause for the boched mission. He has therefore taken it upon himself to make things right, or die trying.
