Before the war, goat monsters like him were pretty common and they were mostly associated with nobility. He is the last surviving member of the original royal family and tried to postpone as much as he could his duties as new King.
He eventually accepted his position, when he understood that winning the war wasn't the end of their trouble. (And by pressure of the council)
Fell in love with Toriel, but didn't really confess until the war was over. Luckily for him, she accepted his feelings.
Is mostly kept in the dark about the groups of monsters who have been abusing their humans, as the information loses itself on the process of registry.
Was the one who decided to adopt Chara and also the one who decided to hide evidence after 'the situation'.
Plants are his jam and you'll definitely see him at his garden in his spare time, which is not much tbh
Personally, he is not in charge of any slaves, despite the technicalities saying The Crown owns all of them. To solve this, he has 'The Seven Chosen'. These slaves are linked to Toriel's magic, but only serve him. They can be swapped from times to times.
Daughter of a Count. Was supposed to marry one of Asgore's older brothers, but he died during the war. She didn't mind that much, to be fair, it was just an arranged marriage.
Served as a Asgore's light during his darkest times, which kept them going strong as a couple when the war ended.
Humans have a high sense of respect towards her because of her kind ways and gentle guidance.
She is in charge of several slaves(number is not exact). She wears a big bracelet with several linkstones attached to it.
Was the one who found out about 'the situation'.
Has verbally opposed the council loud and clear when they decided to apply the punishment to her children.
With the punishment being applied anyway, she became emotionally distant and most of her smiles are faked. She mastered the ability to do it so, though.
As a perfect blend of his parents, Asriel inherited the kindness, the nurturing nature and the sense of duty. He brought light to the palace when he was born, as he was curious and pleasant to stay around of. He had plenty of acquaintances.
Acquaintances. No friends. There was this stupid barrier between him and most monsters his age. Their parents would tell them, naturally, that they were supposed to treat him with utmost respect and that often meant that kids would allow him to win the games. Barely touch him in fears of 'tainting him'. Never, ever tease him in fears of being sent to the mage tower. Those were... Shallow friendships. And he hated it.
One day, when he was on his father's garden, he met a human. Said human had no magic rune on his body to affirm he was part of the slave program. He also seemed to be way too thin and dirty. Not to mention- Hurt! Asriel helped the human and they became friends.
Not just acquaintances. Friends. This human treated him normally. Without worrying about his position or title. Maybe even, he wasn't even aware of it. This nameless human, was just the right amount of annoying and touching and fun he needed.
Asriel soon found a place for this human to stay inside the palace, a room of his own and for some time, it was a fantasy. Their own world.
But they were found eventually.
Asgore and Toriel were surprised in many levels. A human with no identification and no name. A person who their son actually managed to connect. More than that... That human had magic on them. In fact, he were so powerfully magical, one could have mistaken his for a boss monster, if magic was the only thing taken in consideration. He was also charming and easy to talk to.
The human was named Chara and instead of sticking him into the slave program, they had a better plan. They would make Chara their own son. Asriel's brother. He was obviously the most ecstatic about that.
Before coming to the castle, Chara lived with his mother inside the forest. She hated monsters. Her monster owner at the time used to hurt her. But he would do that in such subtle ways that there was no way to detect it in the monthly checkup. The monster doctor in charge of her area, also didn't seem very keen on humans' wellbeing.
She fell in love with another slave and they kept a forbidden relationship that ultimately resulted on her pregnancy. They decided to run away from the monsters, hiding on the forest. Her lover was killed during the chase and she managed to stay alive, but had to live on her own. Including her labor.
She made it sure for Chara that monsters were bad and he was supposed to fear them. Hate them.
Hating monsters he did. Despite having never seen one before. When his mother died - mostly out of starvation - he understood he could no longer stay on the forest only.
He advanced towards the city. Especially at the palace's garden. No one really guarded there because there was no threats.
There, he met Asriel. Asriel was too nice. He couldn't be out like this. What if the monsters got him? He barely could believe when he told him that he was a monster himself. No way. Monsters were bad.
That was their only disagreement.
Eventually, he was adopted by the royals. They were so nice. So kind. He came to love them, despite the voice of his dead mother chastising him for befriending the enemy.
He could feel the dirty looks, though. From monsters and humans alike. Who he thought he was? How come a lowly human like him, (uneducated at that!), become part of the very royal family?
No. Asgore said he wasn't. Toriel reassured he wasn't. Asriel believed he wasn't.
But he definitely knew. There were bad monsters out there and he wanted to catch them.
