DemiTale: Chara

I have a few head-cannons for this Chara. So the first would be about their past - They originally were a human and lived around the time of Human - Monster war. Their social standing is debatable but I would like to think they would have had very potent magic and that they had a loving family.

In this AU the war wasn't as one-sided as in Undertale, so the humans getting more desperate and fearful of the monsters gaining more power, had a "brilliant" idea of making a living weapon to turn the tide of the war. So they probably chose Chara due to their powerful magic and in a ritual that involved a lot of torture, dark magic infusion and probably witnessing their parents getting murdered, allowed Chara to ascend into whatever they are now. So the ritual was a success the human mages created a weapon but Chara probably had their sanity completely shattered by the torture they went through and all the dark magic they were infused with (they are a child after all) likely brutally killed all of the mages. And with that power they were a threat to the whole world which probably brought humans and monsters together to stop them and after long battle they were sealed in the locket and it was given to the monsters before they were sealed underground so that no man could use its power.

Now my second main head cannon is that Asriel was lonely and that he wanted a friend, so by unknown means he somehow got the locket and summoned Chara and I don't know how he befriended them. A minor head canon of mine is that Chara probably has a lot of traumas but Asriel by becoming their friend started to heal some of their mental injuries and allowed to become from a very angry "demon" to basically a "normal" child. Then most of the canon events of the AU happen and Asriel ventures to the surface alongside Chara who is accompanying him. And by seeing what happened to Asriel, without being able to do anything about it, whatever progress in healing that Asriel made was erased and reignited Charas hatred for the world itself. Everything else happens the same.

Now for my head cannon for how Chara acts. I would say that they probably act in a mixture between a child trying to act like a malevolent being and a source of all evil. They probably have similar coping techniques like the OG Chara.

A few questions for the creator. How would you feel if I compared your Chara to Sukuna from JJK? Because they both have and could have a few similarities like the both have forgotten that they once were humans, they probably view every one as inferior to them. But the only major difference would be that Chara became a living embodiment of dark magic while being a child and Sukuna did that when he was already grown up. Another major question is what Chara does in the pacifist route? We already know what happens in a geno route and if you believe in narraChara theory does that mean that Chara sensed that when Frisk fell into underground and sensing something special about them (whatever that is, it is not revealed) and decides to poses them but that back fires unto them and they just get stuck with Frisk (which would be hilarious) and narrate their journey through the underground. And as Frisk helps every one in the underground and more of Chara magic is broken, I would like to think, the more of their memories are returned and by the end of Frisk journey they would completely remember their past. And in the post-pacifist route they would be just chilling within Frisk.
