Parents: Dust sans and Killer sans
Gender: in the closet MtF transgender.
Amoris' name ruffly translates to 'Full of Love' this is because as a child he was a very happy and smiley baby. It was probably also wishful thinking that when he grew up he'd be full of a different kind of love.
When Mori was born Dust and Killer where less then pleased. He was created through soul sex of some kind and was definitely a accident. Dust and Killer didn't want anything to do with the child, but Nightmare intervened. He wanted to have a next generation of killers, in order to continue growing his group. So in short he ordered them to raise him.
Dust and Killer weren't bad parents, but they weren't particularly good ones either. They took care of all of Mori's physical needs, such as feeding and dressing etc. But they paid no attention to Mori's emotional needs. They'd often lock him in his room when they went out on missions, sometimes for hours at a time.
Despite how it may seem, dust and killer do care for him quite a lot. They just never bother to show it. They have there moments of things being good for alittle while, but it never lasts.
Mori was raised in the anti sans base and never left it growing up. This means that the anti Sanses are all the people they knew growing up. They tend to stick with their parents and avoid the others, Nightmare particularly frightens him.
Moris soul hurts when to much magic is used, so dust and killer focused on teaching Mori other ways to fight. They would train for hours on end. The knives where a gift, and are one of Mori's prized possession! Since they were a gift from his parents.
Unfortunately when Mori gets stressed or anxious there eyes drip uncontrollably. His parents usually scold him when this happens since it clouds his vision. Amoris will often try to stop his eyes by rubbing them. But this means that they are often sore.
Despite there best hopes, Amoris was not the cold blooded killer they'd wanted. Amoris has the technical skills to be a killer. But doesn't have the heart. Mori hates hurting people. It often causes mental break downs.
Mori is very timid, and quiet. And normally sad or low energy. He tends to keep alot of his emotional pain internal. Only talking to his rabbit Peekabo about it.
As a young child, mori lived in bliss, in a world of pretend, not fully understanding who there parents where. But one day the illusion was shattered. To this day Mori trys to escape into a imagery world, where they are just normal. Where there family aren't murders. Where things are normal. They write about these things in their book.
The only friends they have or there rabbit, and there pen pal Lucid (not the nightmare dream fusion). They also have a close relationship with one of the anti sans members.
Lastly, about moris gender. She is a girl on the inside. There is a part of her who has always known. She always kind of felt like something wasn't quite right. But she will squash it down inside and ignore the feelings. It's not like she has anyone to talk to about it. So she can't really come to grips with it and fully realise what her feelings mean.
Sorry that bio was longer then expected.
