Apollyon

''Not to be confused with The OMEGA Subject or The OMEGA Subject (Revised), the stories he is part of

""I want to get revenge and destroy you. I want to be the end of everything you humans hold dear.""

Apollyon, also known as the OMEGA Subject, is the main protagonist of The OMEGA Subject (Revised). He is an Alpha Beowolf captured and experimented on by the Grimm Control Program, turning him into one of their Subjects. He was taken to the now-destroyed OLYMPUS Station and given several augmentations.

Apollyon first appeared in "New Beginnings" as a nameless Alpha Beowolf being tracked down by a group of soldiers working for the GCP, lead by Specialist Serap Verzand. Once captured, he is taken to the nearby Station and immediately experimented on. Following his surgery, he is subjected to a series of combat trials to determine his viability as the OMEGA Subject.

Appearance
Apollyon is an Alpha Beowolf of a larger size than normal. He has several patches of white fur, mostly located on his joints. His facemask has also been broken in half, leaving the left side of his face unprotected.

Before Augmentation
Before his capture, Apollyon shows many scars and battle wounds. Standing on his hind feet, he measures at ten feet tall. Many of his spikes are chipped, blunted, or partially destroyed, In addition, the shards of the broken half of his facemask remain embedded in his face. Due to a previous injury, he is blind in his left eye, which is seen through its dimness and lack of a visible trail, in addition to a scar going over the eye.

After Augmentaton
Once his surgery is done, many of Apollyon's wounds have either been healed or hidden. The many shards buried in his face have been removed, in addition to an Enhancer restoring his eyesight. Though this returns the light to his eye, it does not restore the trail. Engraved in the center of his mask is an "Ω", which denotes him as the OMEGA Subject. In addition to this symbol, another can be found on the forehead of the Geist mask on his chest. This mask was transplanted onto him, and is the remains of the IOTA Subject. The symbol on the Geist mask is an "Ι". All of the spikes on his body also received metal coverings, painted and detailed to look like the originals. They are bolted into place at their bases. In the roof of his mouth is also a specially-made gland capable of spitting out and producing venom.

The Enhancers also slightly increased Apollyon's height and mass. Standing on his hind legs, he is now eleven feet and five inches tall. His body has also received some bulk, making his overall build more similar to a Manticore's burly frame than a Beowolve's more lithe one. In addition, the Enhancers also encouraged the growth of more bone plating and spikes, giving his legs and body more protection.

Personality
Little is known about Apollyon's personality at the current date. However, there are some minor facets of it that are known.

Apollyon has shown he has a caring side, such as when he felt warm after saving Lapis' life in Debut.

Powers and Abilities
Apollyon, even before his augmentations, was a considerable threat. During his capture, it is noted that he was responsible for the deaths of a Specialist and four squads of GCPSEC soldiers. In addition, he also destroyed two squads of AK-130 units, one squad of AK-135 units, and a Bullhead. It is also hinted that he has been responsible for the destruction of several villages on the fringes of Atlas. Once he is captured, Serap Verzand realizes that he killed half of the squad while half-blind, leading him to realize that he could have been half-blind for the other parties sent to capture him as well. It was these factors that led Serap to believe he would be a worthy Subject.

Enhancers
As standard for most Subjects, Apollyon was given a series of Enhancers designed to strengthen certain aspects of him. The set of Enhancers given to Apollyon were the strongest conceived up until that point, giving him an edge over many of the Subjects. In comparison to a normal Alpha Beowolf, his hearing is stronger, his body is stronger and faster, he has more armor, he has more spikes, and he is smarter. His increased strength is shown when he is able to deform Duke Melas's shield even when his Aura was channeled into it.

Geist Mask
Implanted in Apollyon's chest is the mask of the IOTA Subject, a Geist. In The Trials, he showed the ability to transition into a gaseous state. Using this ability, he was capable of surviving an attack from the Atlesian spider droid firing its combined weapon and even passing through part of the droid itself. However, he had no degree of control over the ability, and even expressed confusion upon passing through the attack unharmed.

In "Brewing Conflict", Apollyon attempts to consciously use the ability, with limited success. It is considerably draining at this stage, but can be called upon. Through effort, he can even replicate passing through the droid, shown when he waved one arm through another.

Venom Sac
Implanted in Apollyon's mouth is a venom sac, giving him the ability to squirt and inject venom into foes. He has not used this ability to date, and is unaware of it.

Weaknesses
Being a Grimm, Apollyon is weak to the power of silver eyes and can be distracted by large sources of negativity. Even with his augmentations, Apollyon has the build of a Beowolf. His body was built for ambushes and pack tactics, making him ill-equipped for direct confrontations with skilled or enduring opponents.

On top of this, he lacks an Aura like all Grimm, and must rely on armor or reflexes to avoid taking damage. While his age and tough hide grant him an advantage in this regard, he can still be overwhelmed and defeated, as shown in his capture.

His augmentations have even given him a disadvantage. The brain, in particular, became a weakpoint with its inclusion. Damage to it in any shape of form might have drastic consequences on his behaviors and skills.

Following his first encounter with Khryseis Minoa in the Emerald Forest in "A Problem", he once again lost eyesight in his left eye.

Following his first encounter with Headmaster Ozpin in the Emerald Forest, he lost his right arm.
