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 were interrupted when the communications terminal suddenly went offline, leading him to believe ONI had caught on to him.

The communications blackout was however the result of a far more serious threat. That evening, Circinius IV was attacked by the hostile alien faction known as the Covenant. Sullivan's room mate Dimah Tchakova was killed while the cadets attempted to evacuate, and Sullivan was pressed into the defense of the planet with the surviving cadets.

As the Battle at Corbulo Academy started, Hastati Squad retreated to the dormitory hiding in Lasky's room, Sullivan was visibly upset by Dimah's death. Sullivan attempted to activate Lasky's terminal, when nothing happened he realized the comms were offline. They heard screaming outside and saw a Spec-Ops Sangheili killing a cadet. They decided they had to leave, Chen volunteering to take point he waited until the elite went into another room to run. After a short distance Chen stopped, the Sanghieli then deactiveated his active camo revealing Chen to be impaled on his energy sword. The rest of the squad then ran for the armory shutting the door behind them. While Lasky sent a distress signal, the rest of the squad attempted to open the weapons locker, eventually Vickers attempted to bash it open. The Sangheili from earlier started to break down the door causing the squad to hide, Vickers got separated hiding on the other side of the room. As the Sangheili neared the rest of the squad's position Vickers, in order to give the squad a chance to escape, revealed his location to the Sangheili, being quickly cut down by its energy sword. The Sangheili then turned his attention back to the squad, slowly walking toward them until John-117 snuck up behind it and stabbed it in the neck. While preparing to leave, Sullivan questioned why John-117 came for them John answered they were the only survivors Sullivan assumed in the school, but John corrected him, they were the last on the planet. While waiting for the Master Chief to return, Sullivan began questioning what was going on, referring to the Chief as a "giant robot", questioning whether he would even come back. When Master Chief asked who the best shot was, Sullivan said it was him most likely. As they went outside the squad saw their fellow cadets and soldiers dead all around them. During the escape Sullivan was shot in the leg by a Kig-Yar sharpshooter, who attempted to kill him, but John-117 saved him. After Chyler and John killed the Kig-Yar, Orenski carried Sullivan to the Warthog to escape.
