Alright, I think I got an idea for a character...Expect a sheet soon :3
20 January
Testing of blood samples from subject "Spite" have begun. We have isolated the primary mutagenic compound that started the initial rampage in New York City, which we are tentatively coding as NME(Numan Meta-Enhancer)-000, 'Tartarus'. While the sample is extremely diluted, that allowed us to discern one of the notable flaws with this mutagen, that being its limited time frame; while initially, this compound would enhance a Numan's abilities by about ten times their normal facets, this quality is roughly halved with each passing hour. This tracks with the timeline of the subject's capture, as it was roughly three hours of non-stop combat with a large number of heroes before it was able to be put down. By that point, his ability improvement from 'Tartarus' had decayed to roughly a 1.3 times increase in power. The last note to make is while this compound seems to grant excessive power, if temporary, it also causes the power(s) in question to go, for lack of better term, berserk. From footage recovered from the incident, the subject clearly had little control over how its abilities, or even its own body, was acting, showing off wild and violent displays of its enhanced powers with reckless abandon. If it were not for its extraordinarily heighted regenerative abilities, these side effects would have likely terminated the subject long before capture.─ Agent Fischer

We have managed to discern a new mutagenic compound within the blood samples of the subject, currently listed as NME-001, 'Hercules'. Simply put, the drug induces an impressive level of superhuman physicality. When used regularly, we surmise the individual in question would possess unbelievably compacted musculature, typical of most superhumanly strong Numans, serving as both a source of incredible strength, likely able to lift upwards of 20 tonnes, and nearly unmatched durability. It is likely their skin alone would deflect or break most conventional forms of weaponry, including high-yield explosives. It is likely only extreme measures or other Numans would be able to properly wound the individual, and even then, due to their muscle structure, it serves as a highly-condensed layer of tissue that would absorb almost any impact, preventing it from reaching bone, which regardless would possess an even greater durability than the skin layer. Additionally, while not quite possessing superhuman speeds in the extreme sense, their agility and dexterity would be highly improved as well. It is likely they could go from standing still to breaking into a 60 MPH sprint in an instant, and at top speeds, would be able to outrun most terrestrial vehicles by going roughly over 200 MPH. On top of this, their reaction speed would be even faster, able to react to things moving at upwards of Mach 1. Like the previous substance, however, 'Hercules' also has a notable flaw (though it was also potentially an intentional side effect) of inducing heightened testosterone, and by proxy, a greater chance for aggressive behavior or general moodiness. It also causes the user to become more instinctual in their movements, occasionally reacting before they think.─ Agent Fischer

A new breakthrough was made with the subject's blood samples, revealing yet another mutagenic compound, this one being christened as NME-002, 'Asclepius'. It offers a highly advanced form of cellular regeneration, able to restore minor injures within mere seconds and even severe, life-threatening damage, such as lost limbs or damaged/destroyed organs within mere minutes. It also would have fought off foreign toxins and other biological attacks, though was specifically designed so as to avoid interacting with specific chemical compounds; we likely have this to attribute to the subject's new vulnerability to general chemical attacks. Most startling is the fact that, from the data we can inform from our research, the subject could have survived having their heart, and even brain, partially or completely destroyed with this mutagenic compound being used. However, we surmise that any brain damage received and therefore regenerated would have inflicted either short-term or permanent memory loss and amnesia. This may explain the subject's inability to recall most of its inciting incident. Similarly to the other substances, 'Asclepius' possessed an error in its design (though yet again, could have been an intentional design choice); a subject's sensibilities while under the influence of this drug would have been slowed and somewhat warped, comparable to being under light anesthetics. This could have been a way to help the user ignore the pain of any injuries they incurred, or potentially meant to be directly used alongside NME-001 'Hercules' to curb its aggressive side effects.─ Agent Fischer

Our latest breakthrough is, dare I say, the greatest yet, as it shows us the secret behind our subject's most unusual and potent ability; energy absorption. This compound has been dubbed NME-003, 'Helios'. In the height of its power, the compound made its user capable of absorbing upwards of 25% of any form of energy they made contact with, which, when considered alongside NME-001 'Hercules' and NME-002 'Asclepius', would have made the subject extremely hard to terminate even before the addtion of NME-000 'Tartarus'. Additionally, the user could wield this energy in the form of scientifically-baffling Pyrokinetics. These flames deny all explanation, as they burn without regards to any of the natural rules of fire. Not only could it burn under the ocean, but it may even function in space, as well, which is frankly an upsetting notion for myself. We sadly have little explanation to offer on how exactly it functions like this beyond Numan intricacies that go beyond scientific standings. Most interestingly for thos compound, however, is both a lack of a negative trait, unlike the others listed thus far, and even moreso, is how the subject has developed an entirely new usage for the ability beyond its intended functions. The subject's ability to utilize the stored energy through their other abilities is not an intended function of 'Helios', but rather seemingly an ability the subject has developed on their own, possibly intuitively after it reached a new height of power during his rampage in New York.─ Agent Fischer

I was sorely mistaken. Even the effects of 'Helios' pale in comparison to the potential full functionality of the latest and, as far as we are aware of now, final mutagenic compound present in his bloodstream; NME-004, 'Nyx'. It has a deceptively simple function; it heightens the psychic capabilities of the user to an exceptional degree. However, it notably does not have an intended psychic ability it grants, and thus, has theoretically endless flexibility. We presume the reason it developed as a form of Telekinesis for the subject is due to a lack of greater thinking and a focus towards material things, and the need to impose their will upon such things. It is likely that, back at the height of its power, the subject would have been capable of far more than this. This hypothesis seems to be supported by the array of, admittedly horrific psychic abilities the subject showcased when it was under the effects of 'Tartarus'.─ Agent Fischer

This last file has proven exceptionally challenging; after all the compounds had been successfully analyzed and listed, we were tasked with trying to grasp the exact powerset of the subject during its time under the full effects of NME-000, 'Tartarus'. This was no small feat, but with my colleagues, we have compiled what we expect to be the extents of what it was capable of in that first-hour frame. Firstly, while 'Hercules' was certainly improved, it is of minor note in comparison to the rest of the drastic evolutions it underwent. Namely, 'Asclepius' advanced from a rather advanced, yet mechanically simplistic regenerative ability to a full-blown control over their body's composition and functions, theoretically even down to their very DNA. They showed this ability in many jarring and gruesome ways, such as generating multiple limbs, forming entirely new and inhuman appendages (such as a tail, wings, and more), and creating explosive growths of an entanglement of musculature and bone to strike out at others to brutal effect. It could still regenerate as well, obvious, and it was to a point where damage that somehow got through their nigh-impenetrable defenses would barely stay for a few seconds before being mended, no matter how severe.
When it comes to their energy absorption, a safe estimate was that during this period, it was capable of absorbing roughly 75% of any form of energy directed at it, which, in tandem with the enhanced 'Hercules' and 'Asclepius', had turned the subject functionally indestructible. On top of that, it began to form a passive aura around the subject that sapped energy from everything other than itself in a roughly 30 foot radius. This caused materials around it to lose stability and eventually crumble into dust, and living creatures to lose their vitality and slowly become desiccated and husk-like. Lastly, 'Helios' evolved to the point that it eschewed simple flames and converted into launching beams of 'pure' energy, akin to something like plasma. From groundwork forensics, anything these attacks made contact with were destroyed utterly, leaving nothing perceivable to the naked eye or even scientific instruments to be found in its wake.
Lastly, the subject's psychic abilities from 'Nyx' were drastically awakened by the effects of 'Tartarus'. From surviving eyewitnesses and video accounts, the subject could supposedly perform telepathy, and with it, mind-reading, clairvoyance (allowing him to perceive other locations beyond his naked eyes), mind control (though due to its mental state, it threw targets into a wild frenzy moreso than proper control over them), psychic blasts, and some form of psychically-charged teleportation, using sheer mental power to shunt itself through space. It also, at least once, was reported to use its psychic abilities to...Pop the heads of several individuals within a small radius of itself. Autopsies report that it must have been an internal explosion of psychic force focused at the center of each target's brain, to gruesome effect. These are, as far as we are aware of at this time, all the capabilities the subject possessed at the time of its attack on Brooklyn.─ Agent Fischer
