Title: The Ghost Stalker
Name: Unknown
Race: Mutant
Equipment: Railgun and C4 charges
Affiliation: Formerly GDI and the Forgotten
Location: No specific location, but has been sighted many times in red and yellow zones.
Background: The main weapon of the Ghost Stalker is a railgun (he was resistant to the harmful radiation the weapon emitted), which is similar to the railguns aboard the Mammoth Mk. II. It is capable of killing any non-cyborg infantry and most vehicles in a single hit, including the stealth tank.
Against structures, the Ghost Stalker uses C4 explosives that tear apart a building nearly instantaneously. However, the fact that he actually had to get to the building itself limits his effectiveness in this regard.
His lack of health when compared to Cyborgs and the Cyborg Commando means that a Medic is often necessary. In the absence of medical personnel, the Ghost Stalker can slowly regenerate his health by simply wading through a field of Tiberium crystals, as his mutant physiology absorbs the radiation the crystals emitted, triggering cellular regeneration that all mutants experience when in contact with tiberium.
Sightings: The Second Tiberium War and the Firestorm crisis
The Ghost Stalker and his similar companions were deployed several times during the Second Tiberium War and its aftermath. The Ghost Stalker was deployed along with Umagon and the Hijacker in a mission to rescue the mutant Tratos from imprisonment in a Nod prison camp / hospital facility. It is very likely that the kind of treatment Tratos was undergoing at the facility was not entirely beneficial. In that particular event, his ability to destroy building and vehicles with one shot was greatly appreciated.
It is rumored that he assisted in aiding a GDI breakout of a mutant prison camp around the time that GDI was dealing with the Chemical Missile Crisis. He was also present during a GDI attempt to destroy power plants that were powering a Chemical Missile facility, causing some of the defences to go offline. Finally, the Ghost Stalker was again instrumental in destroying a Nod prototype weapons facility - first scouting it out, and then assisting with its complete destruction.
His final known appearance in the Second Tiberium War was finding out the location of Kane's Pyramid in Cairo, and informing Michael Mcneil that Umagon was held captive in its Temple of Nod.
During the brief interim between the Second Tiberium War and the Firestorm Crisis, the Forgotten acquired a number of additional railguns and could equip more of their kin with them.
When the Firestorm Crisis took place, the new Ghost Stalkers served with distinction. They were instrumental in the defense of the main mutant base, but despite their efforts, the base was still overwhelmed as the massive opposition they faced alone was too much to contend with.
The original Ghost Stalker was sent in to retrieve the second piece of the Tacitus from the mutant-intolerant Cultists. He killed their leader, Mortimer, and many cult members, effectively dissolving it. In that endeavor, he was supported by a Juggernaut artillery mech, archaeologist Valdez and a medic, whose medical skills and equipment greatly contributed to the mission's success. The Ghost Stalker had a degree of importance for that mission, as CABAL had calculated a 10% chance of success if the Ghost Stalker were to be killed.
After the Firestorm crisis, Like other members of the Forgotten, the Ghost Stalker and his companions went into self-imposed exile following the Firestorm Crisis. As a result, GDI had to revamp their Commando program to train front-line special forces to replace the Ghost Stalker and his kin.
