He's a horror character with lots of dark edgy shit going on, also very difficult to do considering he has doubles of a lot of letters.
Small warning before going ahead: this is imaginably long, I wrote a shit ton for this, there also is talk of murder, cannibalism, mutilation as well as abuse/ over all torture. He is a slasher guys, so I suggest you step away if the mere thought of such things bothers you.
M (Morals): He pretty much doesn't have any morals, or any he'll acknowledge, other than he considers killing to be an act of mercy (which, ya know, it is when the person you are killing is torn open and in absolutely agony anyways, so he justifies himself in that way). In truth though, he wouldn't ever harm someone who is truly defenseless. (He basically doesn't bother with babies, young children, the elderly, and the mentally/physically disabled.) I don't know why he eats people, he just likes it and has no thoughts on the morality of it, he doesn't care.
A (Attitude): Carefree yet Cruel, hating rules and figures of authority.
R (Routine): He starts most days with a stop at any small gas station, leaving, of course, with a bottle of stolen strawberry milk. He then goes for a stroll, searching for his next victim and spends the late evening and next few days planning how he'll go about killing them.
Other days he spends the whole 24 hours tormenting his victim, picking them apart methodically.
Still other days, and surprisingly often, he stays totally in hiding or on the move, especially after a recent killing, ya know, with law enforcement looking for him and all.
The order is generally as such as he has gotten into a pattern over the last few years; stalk and plan for about 5 days, kidnap, torture and kill, hide and/or move (usually no activity for 5 days (likely at the stalking stage again already)) and repeat from there.
C (Crazy Memory): Killing his father, it's probably the first and last time he felt any sort of really deep emotion. He became numb after that but he remembers it vividly.
U (Unique Ability): He has thoroughly studied human anatomy and he knows how to properly and surgically dismantle a body and prefers this over messily chopping someone apart.
S (Secret): He would like to know affection. However, this, along with most of his other feelings, is something he doesn't understand and keeps buried in his subconscious. It's really not intentionally hidden away but it is a part of him that is really difficult to get to.
V (Voice): Chat Noir has been suggested and I'm dying. I haven't actually decided on anything yet but I am looking, suggestions would be cool. 👀
I (Intelligence): On a scale of 1 to 10, he's about an 11. He's frighteningly smart, excelling at easily outwitting law enforcement and manipulating his family to do things for him. He can hack, pick locks, read and speak about 4 languages, and turn anything into a weapon.
V (Vibe): Cute and disarming, you'd think him to be quite friendly and sweet.
I (Interactivity): 98% of interactions with him end up with someone, or multiple people, dead or seriously injured.
D (Desires): He wants everyone to know pain like he does for one part, thus the desire to torture his victims.
But back to the point of his morals, with death being mercy and all.
Having been tortured for months and being unable to die despite wishing it would all just stop, death is truly a merciful release in his opinion. It frees one from all mental and psychical suffering, in truth he envies normal humans and considers killing them a big favor, especially once he's tortured the hell out of them. Like to be fair, having your limbs and organs and stuff removed methodically while you are still totally conscious, you would be begging to be killed just to have all the pain stop.
L (Love): Love? Never known it, doubt he ever will.
U (Unique Ability): Ha, Double U, makes sense then that he is double jointed and inhumanly flexible.
R (Rank): A bit random but with all the double letters. To specify, rank for me means in his family and among my favorite characters.
So, since killing his father, he basically runs the show as all his other siblings both fear and hate him.
He is an old character of mine and I literally live for drawing and developing him, so I'd have to say he's probably #4 or 5 in the ranking of my top 10 favorites.
E (Employment): If you can even call it that. Self-employed serial killer I guess, lol. He doesn't really need money or most normal human necessities, just the occasional strawberry milk, otherwise he relies on eating the people he kills for sustenance.
