Michael Sullivan

Michael "Sully" Sullivan was an officer cadet of the UNSC Defense Force.

Biography
A native of Emerald Cove, Sullivan entered the Corbulo Academy of Military Science in 2526 as a freshman cadet assigned to Hastati Squad. He had a habit of 'dying' in combat exercises. Despite this, he never lost his enthusiasm and became friends with Thomas Lasky, though the rest of the squad was hostile to the perceived "Innie lover".

Convinced that the Office of Naval Intelligence was hiding something from the greater whole of humanity, Sullivan hacked mission recordings of UNSCDF personnel ostensibly fighting in the Insurrection. He had discovered the helmet camera footage of a Spartan in a three-way battle among the UNSC, Insurrectionists, and the Covenant. Sullivan bragged about the supersoldier's ability to decapitate a man with his hands, and eventually managed to decrypt the entire footage, which showed a Sangheili warrior reflected in Frederic-104's visor, whom he thought was an ODST. Sullivan's activities, however, were discovered by ONI and he was locked out of Corbulo Academy's computer network.

Sullivan believed that he could use the family connections of his roommate Dimah Tchakova to escape ONI. That evening, however, Circinius IV was attacked by the hostile alien faction known as the Covenant. Tchakova was killed while the cadets attempted to evacuate, and Sullivan was pressed into the defense of the planet with the surviving cadets.
