Corporal Wearing was a member of the United States Colonial Marine Corps. She was part of a 31 marine platoon under the command of Captain Paget, aboard the combat ship Hasdrubal that landed on the planet Tartarus, kick-starting a massive series of events that led to an all out battle for survival against the Yautja species, Xenomorph organisms and the godlike Engineers.
After the marines landed on Tartarus, they were suddenly ambushed by a large group of Predators, resulting in the death of numerous marines. Paget decides to send Sergeant Roth and his team consisting of Wearing, Jhalil, Freebody, Rucker, Singer, and others into one of their dropships to fly over to the Engineer ship and secure the interior whilst Paget's team approaches the vessel by foot, attempting to sweep the forest using M314 Motion Trackers to flush out the hunters.
Roth orders Wearing and Indelicato to activate their trackers as the squad enters the interior of the vessel. They eventually come across the cockpit, containing a sarcophagus-like object. Singer suggests that he would be able to get the ship operational and have the ship leave Tartarus and abandon the Predators.
The Elder Cracked Tusk Predator, unbeknownst to the other marines, was observing them withing the derelict and called for the Predators who were battling Paget's crew to retreat back to the vessel to stop them from lifting it. The Cracked Tusk Predator ambushes the squad a second time but is finally managed to be killed by Humble by shooting it with a Pulse rifle after it's Wristblades get stuck by accidentally lunging it into the sarcophagus. Singer manages to get the ship operational and plans to send it to the nearest USCM facility, Ganymede station.
Awakening the Engineer
Wearing and the group are inside the vessel. Wearing is mourning the death of marine Schrader, who was killed by the Cracked Tusk Predator during the ambush. As Singer was attempting to contact the Hasdrubal, Indelicato inspected the sarcophagus-like object that was previously hit during the fight with the Predator. The sarcophagus opens and an Engineer emerges from stasis. The Engineer is immediately hostile and kills Indelicato and sends the others into a retreat. As the group began discussing what they just saw, Wearing describes the Engineer as the "scariest shit" shes ever seen. The marines are forced to hide from the Engineer as it begins taking control of the ship and directing it somewhere else.
Landing on LV-223
Six days later, the derelict lands on the moon LV-223. The Engineer walks out of the vehicle and the marines quickly follow once it is out of sight. The marines begin searching for shelter, food and water. Wearing scans the area and tells Seegson asset-stripper Humble that the floral-forms around them were completely toxic. Humble hugs her, with Wearing asking him to let go. The marines are suddenly ambushed by a horde of Xenomorphs, resulting in Rucker being taken and Jhalil being gravely wounded. As the group are close to being overrun, they are saved by Geryon survivors Angela Foster and Galgo Helder.
They all regroup at Foster's base and the marines are introduced to fellow survivors Chris, Jill and the Predator Ahab. After Galgo reports that the Engineer had visited a temple to reawaken a second Engineer from stasis to kill them, the team formulate a plan to leave the moon. Foster plans for Ahab and Galgo to distract the second Engineer whilst she, Roth, Singer and Humble go to the derelict to deal with the first Engineer. The rest of the team, Wearing, Freebody, Chris, Jill, and Melville are to carry the supplies as well as the wounded Jhalil.
Second Xenomorph ambush and death
Angela's group manages to get aboard the derelict whilst Galgo and Ahab distract the second Engineer. Wearing's squad are ambushed by more Xenomorphs. As they hold them back, Jill and Freebody notice the derelict taking off, with Jill assuming that Angela abandoned them. Wearing replies with "forget them. We're on our own now."
Wearing is suddenly jumped from behind by a Xeno, dragged into a bush and promptly headbitten, with the marines having to retreat.
Behind the scenes
Whilst artist Brian Albert Thies was in an earlier stage illustrating Predator: Life and Death, Andrea Mutti was working on issue 1 of Prometheus: Life and Death, which featured Wearing far more prominently in comparison to her incredibly minor, practically non-existent role in the former. Due to the overlapping issue that a "nameless marine who was part of Sgt. Roth's team from the Predator chapter was required to step up and take a speaking role", Mutti gave Thies rough sketches on what Wearing would look like so Thies could draw her earlier appearances in Predator: Life and Death.
