Michael Breitbach was a Mobian citizen and the chairman of the Mobius Liberation Front.
He spent years researching about successful revolutionary movements of human history before founding the first cell of the MLF. As a result, he emphasized a compartmentalized organization for the entire movement, as well as a ruthless policy where traitors to the cause were concerned.
During the government offensive following the MLF attack on the Trifecta Tower in mid-1922 PD, he was on his way to meet a cell leader and got caught in a security sweep through the area.
In the aftermath of the Manticoran intervention in the system, he assumed the position of Acting President. (SI4)
