Michael Trinity

Michael Trinity is one the Trinity siblings and the pilot of Gundam Throne Zwei.

First battle
When the four original Gundams were about to be captured by a joint AEU-HRL-Union, Michael and his siblings intervened and saved the Meisters. He and his siblings then retreated back to space, reviewing the Gundams' previous missions. They then rendezvoused with the Ptolemaios to inform Celestial Being of their intentions.

Mass murder
Michael and his siblings began mass scale attacks around the globe to show the world that Celestial Being is "serious", having no regard for civilian life. They took out Professor Leph Eifman to prevent him from informing the world about Celestial Being's true intentions.

Another attack at a Union base drew the final draw for Setsuna F. Seiei, who determined the Thrones to be increasing conflict. He attacked Michael, forcing him to defend himself. He tried to use the Fangs but Exia was too quick for him.

The End
Unfortunately for the Trinitys, their benefactor, Laguna Harvey, was just using them to force the world to accept defeat and then be reborn with a new army of GN-X. The Trinitys were overwhelmed by the number of these new suits that they were on the run.

Michael was killed by Ali Al Saachez, a mercenary who worked for Harvey and then killed him. Saachez took control of Zwei, bypassing the biometrics scan.
