Demo Man

The Unnamed ODST Soldier was first seen in Episode 3 "Number One" of Season 9, though he was heard at the end of the previous episode. He appears to be the leader of the soldiers in the Bjorndal Cryogenics Research facility, though this is unconfirmed.

Biography
The ODST Soldier was, at some point, transferred to the Bjorndal Cryogenics Research facility, possibly to command the forces there. Eventually, Freelancers North and South Dakota infiltrated the place to retrieve a data package, the latter reaching it without getting caught, or at least noticably by the majority of the soldiers in the base. However, just as she retrieved the package, South was seen by a soldier carrying two mugs full of what appeared to be coffee. She threatened to shoot if he raised the alarm, which was in range of his arm. Deciding to alert the others of South's presence in the base, he lunged for it, but was killed before hitting he could hit it (though his body did hit it, sounding off the alarm). This caused the ODST Soldier and the others realize that intruders were in the facility, and thus they sprang to action.

Soon enough, the soldiers and the ODST Soldier himself were surrounding the two Freelancers, with the latter at the controls of a machine turret. He referred to them as "assholes" and demanded that they return the data module before they killed them both. But before he could do so, an unnamed Freelancer--referred to as Number One in the episode--attacked the men around him after sneaking inside. He turned and attempted to attack her, but was kicked away from the turret by the Freelancer.

The three Freelancers then started fighting against the soldiers, having much success. However, the ODST Soldier was able to reach his turret again and fire at the three, injuring North in the process. He attempted to hit the other two, but was stopped when Number One used some sort of cable to rip the turret downwards, below his own feet. This ripped the platform he and other soldiers were on to collapse in two, and thus leaving the soldiers to fall to their deaths in the waters below. However, the ODST Soldier could be seen landing on the edge of a lower platform, getting up and going somewhere off-camera, escaping from the plummeting men that might knock him down as well.

Later, as the Freelancers were escaping, the facility could be seen exploding and collapsing in the frigid waters. It is unknown if the ODST Soldier survived, or died in the explosion, though it could be implied that due to him getting up on the ledge that he escaped.

It should be noted, however, that North and South were not seen planting charges of any sort in the base, so the question of why it blew up goes unanswered. It could be said that the soldier activated some sort of self-destruct sequence. If this is the case, however, it would be more likely that he was killed in the explosion. This is all just pure speculation, however.

Appearance
He is only referred to as an ODST due to his most prominent trait: the ODST helmet he wears. He has full body armor, and is slightly taller than the other soldiers, making it more likely that he is their leader. He has much ammo strapped across his chest and belt, and carries a Shotgun on his back. His colour scheme could be stated as Primary: Steel, Secondary: Red.
