Nobody's quite sure why this suit of possessed armor with a soul-devouring sword decides to go by "Grump Suit" most of the time, because they are almost always calm or cheerful, except when "hunting." When asked, they usually don't respond and stand still or pace for several minutes, and when they do, it's usually just saying that it fits with stuff they've gone through and prefer not to dwell on.
Their list of known weaknesses comes largely from an explanation of the powers animating them and going through a psychological analysis. The resulting psych profile had them testing positive for sociopathy, borderline personality disorder, dissociative identity disorder and attention deficit disorder, leading to them fully admitting that they are extremely easy to keep away just by reminding them of the vast number of things they have experienced, when they aren't actively doing something. The remaining weaknesses result from the variety of necromancy they primarily rely on, which they call "Dar-formed."
Whenever asked about what "Dar" is, they state it is the literal power of hell without the limits of human minds making it comprehensible, or they state it is the result of a subjective reality of psychic force being polluted by every horrid emotion involved in war, famine, poverty and post-scarcity economies. This "subjective reality" is what allows them to control the warping of reality using what they call "eldritch nonsense," warping the flow of time, twisting space and occasionally making anatomically, and sometimes geometrically, impossible monstrosities out of bystanders and collateral fatalities.
Because it is part of what keeps them functional, large groups of heavily religious people and strongly agnostic people can interfere with the function of their magic by altering how the magic acts due to their beliefs, which includes the forces animating them. Their answer to why they themselves aren't effected by Dar exposure is that their soul is locked up behind a number of barriers intended to prevent corruption from significantly more hostile varieties of magic. And that Dar has to corrupt its way through what holds their soul in place to begin with.
With the form of Necromancy they use, they can cause rapid decay of almost every kind, create diseases, interact with souls, create undead minions and perform exorcisms themself, although this variety of exorcism is known not to be effective at disabling them due to an incident with a space distorting autistic savant redirecting it back at them and away from the spirit they summoned to enhance their power. They also have a tendency to use it to temporarily bind the spirits of bystanders to ensure that fatalities can be undone.
The vulnerability to exorcisms and "Holy" magic is, according to them, caused by the fact that they are a bound soul held in place and allowed to interact with the world through magic made of hate, death, fear and stubbornness. Exorcisms often leave them limp on the ground, with bizarre, multi-colored flames that ignore the combustibility of materials or strange "negative light" that makes those exposed to it scream in pain and develop near-instant necrosis of exposed tissue. One one occasion, the ground around them started frosting over with a massive static charge buildup forming that caused an extremely bright and loud, though not damaging, discharge when "Grumpy Suit" recovered.
Their "storm magic" includes manipulation of wind, electrical charges, temperature and water, though steam must be cooled down into water vapor before they can affect it. Despite the name, "Grumpy Suit" has shown to be able to use it for highly detailed uses unrelated to storms, such as creating pulses of magnetic induction heating through electrical manipulation and creating highly precise ice sculptures.
The "Eldritch Seraphim" moniker was coined when Grumpy Suit encountered a homicidal extremist Muslim who attained a level of divine favor, resulting in Grumpy Suit somehow growing feathered wings that had a mixture of black, purple and white feathers and forming a highly effeminate face within the armor that is Grumpy Suit's body. The resultant fight saw the area subjected to a quarantine due to becoming covered in insanity-inducing power of two flavors: The "Holy Wrath" of the divinely-empowered Muslim, causing those exposed to become violently devoted to any cause they believe in, and the geometry warping, logic breaking, power of the "Eldritch Seraphim," causing those exposed to begin turning into physically-impossible entities incapable of comprehending normal reality.

Sort-of edgelord in that they find their powers torturous, but specifically because other people tend to be assholes about it and it gives some very significant vulnerabilities. Including being able to be legitimately wounded by the power of prayer. They don't act edgy unless they are in the "Oh god, why is there an infant Old God in the form of an angle defiling reality here" state. Basically, they're a loony madman until they see something they think needs to be gotten rid of as soon as possible, then they go for either gleeful murder or just head over to the thing to calmly stab/shock/freeze/warp beyond physics it and destroy it.
Like, the idea I have here is basically that they tick off most of the edgelord list, and a few things from the mary sue list, but for very different reasons than most characters would. They are tortured by their powers because people tend to be assholes to necromancers and people who can cause permanent insanity as collateral damage, and the powers bring with the serious vulnerabilities. Like being able to be killed by sufficient quantities of agnostics actively denying the way their magic works or trying to quantify it. And needing to turn into an eldritch monstrosity that happens to be angel shaped to deal with a crazy Muslim who happens to have been empowered by their image of God, turning the site of the battle into an eldritch location that can make people insane zealots or insane gibbery things.
From the Mary Sue side, we have the fact that they are basically unstoppable and only the evil guys ever actually hate them. The former has quite a few exceptions, among them being a very strong refusal to run making escape fairly easy. The latter is because they are usually just very silly and simply don't share normal morality, considering corpses that the soul has left to be a meaningless lump of meat usable for other things. Like making a new, less damaged, body for the soul said corpse used to have.
Like, it's basically a half-plot-device, half-comedy-relief character who just kinda mops up collateral fatalities and deals with things that most would go crazy dealing with. And they happen to have a hard-on for maiming assholes who use light-related and divine magic to screw things over, actively putting themselves in the way of their greatest weakness to make sure the asshole gets locked up or killed.
Think Saitama meets the Crouching Moron, Hidden Badass trope. Most of the time, they just kinda joke around and casually slap aside mooks. But you can have the big heroes beaten down, only for the guy who'd be only comedy relief in just about any other series to drag everyone's ass out of the fire by beating down the big bad of the arc who'd be just about utterly impossible for the main cast to beat but gets downed by one trick with one of the several major power types that Grumpy Suit has. Like space-warping over to a teleporter to backstab the cocky bastard. Or freezing all the water a strict hydrokinetic has access to. Possibly whack ghosts with their sword to deal with a sudden portal to a very bad afterlife.
Essentially, if you write yourself into a corner and figure out a reasonable use of the guy's well-defined power set that derails the whole thing casually. Or you focus the story around them being the Big Bad of what turns out to be a Villain Protagonist series/introductory arc and have it be very clear that Grumpy Suit can be stopped if you know how to exploit his weaknesses. Or have said arc that ends with Grumpy Suit being almost downed be a case of Grumpy Suit having a bad time and getting screwed over again for the whole "army of undead/physically-impossible gibbery things" situation they do to deal with mooks.
The big point is that if they weren't sarcastic/cheerful about all of it, they'd be a definitive Edgelord. Powers of hell, necromancy and eldritch might? Being a walking storm, complete with causing "cold and dreary day" being an almost at-will power? Constantly tormented by your powers? Yeah, heavy Edgelord warnings.
