AUTHOR'S NOTE: Those of you who have completed the game must be aware of the opening scene where Chara falls down the hole into the underground. The time period said 201X. The game insinuates that it has been many, many years since that incident happened, which would mean Undertale's actual timeline is pretty far off into the future; however, the game's exact date is quite ambiguous. The war mentioned in the intro happened centuries ago-as we can see the humans fighting with spears-but Chara was definitely from our current generation. All of the other souls fell after him, yet the game still insists that by the time Frisk has fallen down the hole, no one has seen a human in a very long time. The timeline for the fanfiction is as follows... Old War centuries before 2000's - - - Chara falls down the hole somewhere in the 2010's - - - Over the course of twenty or thirty years the lost children meet their fate - - - Another ten or so years past and Frisk finally falls down and begins the game we all know as Undertale. (Specific era is up to interpretation. But a safe assumption is around the 2050's. Society is definitely more advanced than 2015, but people have not changed enough to prevent what happens in the plot.)

It was finally over.

Frisk's arduous journey had come to end at last, and everyone was happy and free. Better yet, they did it without killing anyone, not a single person. Even Flowey received mercy- who turned out to be Asriel, the departed prince. That was after he damn-near eviscerated everything in existence, including by tampering with numerous timelines.

Why they had done it, they could not say, not to any of their friends anyway. The knowledge of various timelines, the ability to alter reality, was a secret. A special power no one else could harness. Even if Frisk explained themselves, what proof did they have? Who would believe them, when after every RESET, all of their memories would be wiped clean, unaware of the higher powers at work. It could only be summoned via magical SAVE POINTS scattered across the third dimension, or on the very fringes of demise. Frisk's inner determination would allow them to shatter the walls of death, to tear at the very fabric of reality, an infinite and unflinching power...

It took two tries.

Their first attempt resulted in a "neutral ending". Frisk climbed the mountain, tripped on an upturned root, and fell down the chasm into the monster world. Whilst trapped there, they met their beloved friends Toriel, Sans, Papyrus, Undyne, Alphys, Mettaton, and Asgore. But the first person Frisk met, the very first face they encountered was Flowey.

And he tried to kill them.

It seemed all-too-suspicious for these flying "friendliness pellets" to not be a trap. Especially since Frisk knew the legend. The legend of a great war between humans and monsters. Ending in the human race's victory, allowing them to dominate the world while the monster race was banished to a harsh exile underground. Ebott Mountain was said to hide the portal, and there were many rumors exclaiming that children who wandered there would never return.

So why would a monster be so nice to a human? Probably to the first one they might have ever seen at that? Then Flowey slipped up in his impatience with Frisk's constant dodging of said "pellets", and accidentally called them BULLETS. This was when Frisk tried to flee, but Flowey trapped their soul, making escape impossible. If Toriel hadn't intervened, Frisk would be dead. And this happiness they all share wouldn't exist either.

Many battles, puzzles, bad-puns and near-death experiences later, Frisk had defeated Asgore- King of all Monsters. But Frisk refused to kill him. Frisk was a merciful soul, and they would not sacrifice the life of another just so they could escape to the surface. The barrier that prevented the monsters from escaping was made with a powerful seal. A seal that could only be broken by collecting seven souls, all human souls, and then combining them with a monster soul so the breaker of the seal could become a god-like being and destroy it once and for all.

Frisk gave up their last chance to return home with their own kind; friends and family- so that Asgore may live. They resigned themselves to returning to Toriel, leaving behind all hopes of resuming their previous life.

That was when Flowey attacked.

He killed him. Right before Frisk's eyes. Asgore was destroyed, not just murdered, but struck at his most vulnerable moment, already beaten and broken from the battle he just lost to the human child. Worst yet, during the prior conversation the two were having upon Frisk's decision to spare the king, Flowey took the opportunity to absorb the captured souls. He became an eldritch abomination, torturing poor Frisk in an endless battle.

But Frisk had determination!

The determination to stop Flowey, to avenge Asgore, to save their friends and home world from Flowey's wrath and lust for destruction. That determination called forth the six lost souls, releasing them, and bestowing Frisk the power strong enough to defeat Flowey.

He was powerless once reduced back to his weak, feeble plant form. He gave up. He told Frisk to kill him. He dared Frisk to kill him. Yet, they could not. Frisk was not a killer, not a murderer like Flowey was. They could've done it, and it took a second thought to keep them from killing him, for Flowey had pushed the child to the brink of abandoning mercy. No one would blame Frisk after all he had done. But Frisk felt something. An intuition that there was more to the story. That Flowey could be saved too. That he deserved mercy. Frisk knew sparing Flowey would not be a decision they would regret, it would be the right choice.

The darkness came anyway.

Even after all of Frisk's heroic deeds, their struggles and sacrifices, still Frisk found themselves trapped in limbo after the battle. It felt like they had spent an eternity there, unable to move, speak or see anything other than pitch blackness. They could hear voices, the voices of their friends' prayers. They were all right. The world moved on without them. Just as they were about to accept this as their fate, Flowey appeared yet again.

This time, not as an enemy. But as an ally. He offered Frisk a second chance. A chance to LOAD, even after he had destroyed their SAVE FILE. He gave them a hint. A hint on how to get a better ending. An ending that would allow everyone's freedom, including thier own. Where nobody had to die. Frisk put their trust in Flowey. With a few choice actions, the timeline was altered. Even after Flowey was exposed as a traitor yet again, Frisk found out Flowey was not a person, but people.

There was a reason Flowey was aware of the abilities to RESET, LOAD and SAVE. A reason why he kept switching from passive to sociopath. Flowey had two souls inside of him, Chara and Asriel. And only human souls had the grace of determination.

Asriel was the long-dead Prince of Monsters, Queen Toriel and King Asgore's son. He was the innocent soul, tied to the ravenous beast that is Chara, who is the hidden persona of Flowey. Asriel was merely a child when he was murdered by humans. Chara was a human boy, who, like Frisk, fell down the hole while climbing Mt. Ebott and found himself trapped in a realm inhabited by monsters. But Chara was not like Frisk in any other regard. He was a hateful child. Chara despised humanity, and after much prodding, Asriel finally told Frisk the reason he climbed the mountain.

He was going to kill himself.

Chara was born long before Frisk, raised in a humble village that no longer exists today. At the time, it was blessed with the most beautiful golden flowers. They grew nowhere else. Yet, despite the beauty and tranquility, there lay underneath that happy guise- a much darker, uglier truth. Chara's life was miserable. He was abused by his family. He had no friends to comfort him, and the villagers turned a blind eye to the crimes committed in his home. After years of isolation and despair, the boy's will shattered. He ran away from his village, to a place no one would dare try to find him and force him back: To Mt. Ebott.

His original plan was not to jump down a hole, but off the very peak of the mountain. Unlike Frisk, he did not believe in the old legend, nor did he really care. Still, he fell, and to his dismay he survived. Asriel found him injured and crying out in agony. Toriel and Asgore tended to Chara, and after some time, they grew attached. Seeing that the boy had no desire to return to the surface, they raised him as their own. But Chara was too scarred, too unforgiving, even when presented with love and charity. He was not grateful.

As karma would have it, the boy never fully got over his wounds. They healed well-enough, but he supposedly caught a nasty infection, one that nobody detected, and succumbed to illness. When he died, Asriel was heartbroken, weeping over his adoptive-brother's dead body. This left his young soul very vulnerable, so with Chara's determination to survive, to get revenge on the humans, his soul dove into Asriel's body, creating the first-ever fusion of human and monster. Asriel was now powerful enough to pass through the protective seal on the barrier, and the first place he went to was to Chara's village.

The villagers were outraged. Asriel had agreed to take Chara's body to the village because his last wish was to see the golden flowers, but when the humans witnessed a monster for the first time in centuries, they had assumed he killed the boy. So they attacked Asriel with all of their might. The soul of Chara wanted to kill them, but Asriel did not, and as it was his body, he overwhelmed Chara's will for revenge and refused to fight back. Tragically, Asriel returned home, bloody and broken. His parents found him in the palace garden, where he would soon after die in his mother's arms.

The two children were now dead. It wouldn't be until many years later that Frisk would enter the timeline.

Thanks to Asriel, Frisk knew the full story. It was that information that allowed them to succeed on their second attempt, the one that would yield a "true ending". After uncovering the truth from traversing the Hidden Lab, Frisk was equipped enough to defeat Flowey's true form, save not only all of monsterkind but humankind as well. Because Chara was not done. Chara's determination remained. In an experiment gone wrong, the ashes of Chara and Asriel's god-like body were collected, their combined souls placed in a new vessel. A little golden flower.

This is why Flowey was the way he was. Only by the time he met Frisk, he was far worse. Flowey's sanity hung by a thread. Frustrated, died and then revived, reenacting countless timelines and exhausting every possibility- he grew bored of everything and everyone. Chara was intent on the extinction of humans no longer. No. This time. The whole world would be eradicated. And the next, and the next, and the next. Over and over and over.

Frisk fought this evil. Frisk prevailed over this madness. Frisk was only a child, but their determination proved far stronger than Chara's. The barrier was destroyed, the monsters free, and the dawn of a new world shone upon them. However, they would quickly discover…

In the human world: It's kill or be killed.
