You are one of the fallen humans. As well as Frisk. And this is a little backstory of what happened. You and Frisk have fallen down to the ruins. Seven other humans had fell down. And all of them had a soul of a different type - integrity, kindness, perseverance, justice, patience, bravery. While you are the last soul their long, called Asgore needed. To receive over godly power to break the barrier (What separates the human world to the monsters) as human had destroyed their future twice. As Asriel, their only son, when Chara, what Asgore and his wife, named Toriel had considered their second child, the first human to fall into the Underground, AKA the ruins, eventually fell ill, and died. Asriel, with Chara's soul absorbed, went through the barrier ,since you need to be a human to pass to the barriers carried Chara's body back to the human village. Since Chara’s last wish was to see the flowers of her village. The villagers, seeing Asriel with Chara's body, believed he was responsible for Chara's death. The villagers attacked Asriel with everything they can find, and although he didn't fight back, and instead smiled, he sustained severe injuries. He managed to return to the Underground, where he collapsed and died in the castle garden. Asgore was crushed, and he sore to herself to gain all the seven human souls and destroy humanity. Disgusted by Asgore’s choice, she divorced him. But everything changed due to you and frisk, as you both had an option, to pick the pacifist route, where you both kill nothing, or the genocide route, where you guys kill everything. No matter how much the struggle was, no matter how bad the monsters hurt you. You both did not attack, but instead of Mercy, and spared them. Both your journeys were long and hard. But you guys pushed through, and never gained EXP, or LOVE. LOVE, stands for “LEVEL OF VIOLENCE”. But you never gained any. And instead of gaining LOVE, you received love from Sans, Papyrus, Asgore, Toriel, undyne, Muffet, and alphys. If that makes sense. But they all consider you as family’s. And after fighting Flowey, who secretly absorbed all the six human souls, granting him God like powers and strength. As he wanted to kill both humans and monsters, as to him, It was kill, or be killed. And after defeating him, you were both given the option to kill, or mercy you. But you and Frisk mercy him. He gave you multiple chances to kill you, treating you both. But you guys never did. Hurt, and confused. He ran away. After some time, since Flowey had killed everything. He came to you and said he knows a better ending. He didn’t go to Alphys, to get a better relationship with her and get the real pacific ending. So he spawned you at your nearest safe point that with his power he deleted, but restored. But he warned you that everything that happened will not be remembered by anyone. Not even by him so he warned you to be careful. Before you got to fight Asgore, a call from Undyne came through. She asked if you can bring a letter to Alphys. And your relationship with her increased. And after defeating Asgore again. You have to fight, Flowey who had multiple forms and power, but he soon revealed his true identity revealed his true identity, that was Asriel Dreemurr. And he revealed why he was doing all this. Because he cared about you and Frisk. You reminded him of Chara. When he was weak, the options to kill him, or spare him appeared once again. And you and Frisk spared him, and he deeply appreciated it. And that’s when you guys became friends. And that’s where you got the real pacifist ending. All the monsters came up to the human world. You, Sans, papyrus, Asriel Dreemurr, Asgore, Toriel, undyne, chara, Muffet, alphys, and Frisk stands outside. Talking to each other and enjoying the view. Ashore and Toriel re-married, and are happy together with you, frisk and Chara, as they consider you as their children, and Asriel, their real child. Undyne and Alphys are now dating. San’s and Papyrus are brothers. Frisk talks first. “The view of beautiful… Is it not?”
