◈ Normally very serious, especially when out on a mission. Best described as gruff and to the point with very little patience for nonsense.
◈ Has a very low view of demons. To the point where he views them as vermin more than actual sentient beings. Despite this prejudice, however, he will begrudgingly work with a demon if the organization orders him to.
◈ Doesn't particularly care about humanity's perceptions of virtues or sins, being well beyond both concepts like the rest of his kind.
◈ Will fight as pragmatically as possible in any given situation, searching for the quickest and most efficient means of taking down an opponent with as little life lost as possible, be that human or otherwise. Does not always show mercy, especially when demons are involved, and in some cases he has even been known to be uncharacteristically brutal in regards to how he dispatches them.

Enhanced Physiology: While not as overwhelmingly powerful as they were in their original forms, angels still have the ability to improve their material vessels to a very large degree. This makes them vastly superior to normal human beings when it comes to just about everything having to do with their physical capabilities - they can move faster, stay active for longer periods of time, recover from wounds quicker, are capable of besting humans who are in their physical prime in a contest of strength with naught more than the slightest exertion of force, etc - yet this strength is still vastly inferior when compared to that possessed by shapechangers such as werewolves or werebears, to say nothing of extremely powerful and ancient undead like vampires.
Biological Immortality: Angels are eternal beings by nature thanks to the higher existence in which they reside, yet by lowering themselves into a human vessel they may truly partake in the macabre dance between life and death, albeit not death from sickness or age. Nay, through violence, injury, and intent only may the vessel of an angel meet its end and nothing else. Thus it is that the clawing hands of Chronos will not touch them, nor shall the withering breath of Nergal mar their forms, for though they walk to and fro within our midst they are not of us. Being entities of spirit and light rather than flesh and blood, their lot is eternity just as mankind's lot is to falter and choke in the ash and in the dust. So it is that when an angel's vessel finally does die, they are revoked from the material realm back to the higher planes in which they reside, unable to return until another vessel to facilitate their consciousness and essence is found.
Smite: While the full breadth of their abilities are hampered severely thanks to the physical forms they must take while on Earth, some angels retain the power to channel a small fraction of their true essence into the body of their foe, destroying whatever physical form they may possess down to the subatomic level while simultaneously burning away their soul. This power does have two major drawbacks however, the first being that the angel in question must be making physical contact with the entity they wish to smite, and the second being that the power is less effective against extremely powerful beings. Some examples of this include vampires and other undead on the level of - or even exceeding if such a thing is possible - Dracula, and demons on the same level of power as Satan or one of their many infernal lieutenants. Because of this, most supernatural and even mundane creatures on the levels mentioned above will merely be inconvenienced by the use of this power at best, and somewhat singed at worst. Additionally, angels who use this power repeatedly over a short period of time run the risk of burning away their own vessels as well, the essence they wield being far greater than anything their mortal shells were meant to contain. It should be noted, however, that such overuse only affects the angel's physical form and not their actual being.

Being the ancient entity that they are Malakh has kept a close eye on Earth for a very long time, as it was the one place demons and other supernatural beings tended to show up the most, lured in by the overabundance of mortal souls no doubt. It was during this multi-millennia long period of observation that they eventually became aware of Josephine and her organization and, being moved for the first time in eons by its cause, elected to lend their skills and knowledge to it. Finding a suitable vessel wasn't easy, as they didn't want to pick someone whose sudden disappearance would draw undue attention, but they eventually managed to place themselves within the ragged and worn body of a factory worker just as the man was about to perish from a fall. Using this moment of shock to their advantage, Malakh quietly slipped in and overrode the man's consciousness just as he was about to hit the ground, strengthening this new vessel so that it would survive the impact and be of better use. This accomplished, he quickly made his way out of the factory and over to the organization's headquarters.
And the rest, as they say, is history.
