Panfandom Ponderings and Things of Note/Impressions
【PANFANDOM PONDERINGS, THINGS OF NOTE, AND SPECIFIC ABILITIES PERMISSIONS】
Also known as a really summarized "weird shit about Allen and how it might relate to you".
Nutshell
⟶Inhuman left arm he can transmute into a sword or clawed form. Holy in nature. Burgundy in color and smooth, warmer to the touch than rest of skin and cooler/harder towards his fingers. Green cross embedded in back of hand. Generally always hidden under long sleeves and gloves.
⟶Cursed left eye/the scar on his face that allows him to see the souls of akuma (very canon specific), as well as note related dark auras from powers. Likely applicable to demons/demonic entities and powers. Doesn't apply to demihumans of darker natures/abilities.
⟶Host to a Noah, a darker and extremely powerful entity residing in his mind. Mostly sealed/inactive still, but there and able to be roused. Innocence/holy attacks can waken it further.
Innocence and Exorcism
Allen is an Exorcist, a user of a substance/weapon called Innocence which is of a holy/Christian nature. Notably he wields a nearly six foot broadsword (which is actually his left arm) that can only cut that which is "evil" - with humans it passes harmlessly through them. "Evil" is a very vague term, though, as it can hurt Allen himself because of the Noah in him. It should be noted that in entities that are possessed or exist in shades of gray, black and white sides, etc., that it only cuts that particular part of them and leaves the human part unharmed, save for scarring (and arguably that's the cells that are corrupted/etc being scarred).
Cursed left eye
Allen's left eye is cursed so that he sees the corrupted/despairing souls that power metal/Dark Matter weapons called akuma. While this is extremely canon specific and it's not implied that he can see ghosts or anything else of that sort, demonic energy/cells or corrupted souls could theoretically be a parallel. Humans that are half-akuma in canon in that they have cells in them that come from an akuma and possess weapons they can activate don't register as anything strange to Allen until they activate the weapons/cells, and then he just sees a vague dark aura around them. This is the most likely panfandom sight he would have.
Additionally, when he activates his eye or it automatically activates around anything he could see with it, the manga shows his entire left eye turning black with a red bull's eye and a gear-like monocle hovering over it. As I play him, normal humans do not see this stage of it (canon never shows normal humans reacting in the slightest) and I take it to be manga-ka artistic license, but characters with a supernatural sight? Sure! I'm down for having them see it and potentially unnerving Allen if they comment on it.
Normal humans can see his eye... maybe... if it becomes much more like an akuma's as it did for a brief period in canon, where his scar also shifts and becomes more intricate, but those situations are rare and would have to develop that habit again; possibly after becoming injured again. DUNNO, FOR PLOTTING. Manga-ka is a vague, inconsistent troll, btw.
Aura and Appearance
Allen's physical appearance is odd, young man with snowy white hair, silver-gray eyes, a scarred left side of his face with a pentagram curse, wine-red left arm with a strange plated-style hand with a green cross embedded in it and tattoos on one shoulder. [More here.] See appearance. But beyond that, there are some strange spiritual/supernatural aspects about him that could be sensed:
(Innocence user) Because of Allen's very late canon, he has a rather confusing power or aura he gives off. His weapon has a pretty noticeable on/off activation, and when he pushes himself (higher synchronization) especially with the sword he can register as a very strong/holy/white kind of power (shounen protagonist). Even other Exorcists, who normally don't seem to show spiritual sensitivity, notice this.
(Noah) However, as he becomes closer to awakening as a Noah, there is an aura he has about him, described in canon as "cold and savage". If he is in that sort of state it will almost certainly register as a cold kind of taint, but as it's not even certain the Fourteenth Noah is evil (read: highly unlikely, shades of gray after all) it would be a darker kind of presence. I am up for figuring out how confusing to panfandom sorts this might be especially if he's using his Innocence, as these are sometimes considered to be polar opposite forces that exist to balance each other!
(Curse) Allen's scar on his face, specifically the pentagram mark, is technically a curse from his adoptive father. Again, this is fairly specific to akuma and the direct cause of the sight Allen has, but it is possible someone could notice something strange/different/an aura around the pentagram even when Allen doesn't use his eye.
